“I can speak French”; “I can speak Spanish”

“Quel est votre nom?”; “Mi nombre es Arish”

Being able to speak a language apart from your native tongue, definitely adds an exotic appeal to your personality.

As a multilingual…

  • You have an entirely different vocabulary to play with.
  • You can communicate with the people living on the opposite side of the world.
  • Maybe you get to date a French woman or an Indian guy, which otherwise would have not been possible, if you didn’t share a common medium of communication.

“Knowing an extra language adds so many new possibilities in your day to day life, be it studying abroad or simply being able to pronounce those tongue twisting French wine names in that fancy restaurant.”

But what about the process of acquiring a new tongue?

Well we know it is not a piece of cake…

especially if you are encountering a new language for the first time, for things like “lack of time”,& “no people to practice with”…cause several new language learners to give up mid-way, but with the arrival of 

 E-learning platforms, language learning was revolutionized.

Some popular language learning apps

What are the benefits of e-learning apps?

  • Now you can learn at your own pace.
  • At the time you choose.
  • You have digital companions to practice with, 24×7.

“Okay I get it, online learning is better in every sense…but which platform should I choose? There are way too many of them…& all seem pretty good to me.”

“Hmm..let’s see what Google says..”

which is the most widely uesd language learning platform

Yeah..as expected it is the “Green bird Duolingo..!”

Why is Duolingo the best online language learning platform?

Well, not only because Google says so, for Duolingo was estimated to be valued anywhere around $2.4 Billion Dollars in 2020 with an astounding user base of 500 million registered users!

The platform offers 95 different courses in 38 different languages.

Duolingo also generated around $161 million dollars in revenue, in the year 2020.

So Yeah…I think it is safe to say that Duolingo is currently at the pinnacle of online language learning platforms.

What are the steps to build a Duolingo like app?

To develop a language learning app like Duolingo, follow these steps:

Step 1: Gamify

  • Make the interface more like a game.
  • Introduce levels, targets & competition.
  • People love collecting achievements & rewards.
  • Give personalized tips on how to perform better.
  • Make the UI/UX interactive.
  • Overall, make the entire process fun for the user.

Step 2: Simplify the interface.

Simplify the interface
  • The app should be easy to use.
  • The user should at no point feel lost.
  • The app should constantly guide the user.

  • This way you’ll be able to grab a larger subscription base.

Step 4: Add Social Network integration.

Add Social Network integration
  • Simplify the registration process.
  • Take Social Networks such as Google & Facebook for quick & effortless registration.
  • Make the registration process as short as possible & as simple as possible.
  • Those lengthy registration forms often result in potential users losing interest & leaving the form altogether.

Step 5: Add Push Notifications.

Add Push Notifications
  • Make sure the learners don’t leave your platform.
  • Integrate Push notifications in your app to turn them back to their course.
  • Use short personalized messages to grab hold of their attention.

  • Cost of frontend development depends highly upon the language you choose for the same.

3. Back End Development:

  • Factors such as languages, frameworks used & hosting servers add to the cost of development.
  • Node.js costs less when compared to Java’s.
  • Similarly Microservices cost higher but come with better, futuristic features.

4. Designing:

  • Vagueness in what exactly to want can lengthen the design process.
  • Time & research involved in creating a platform-perfect design is also an influencing factor.

5. Testing:

  • It is one of the factors that influence the overall cost of the project.
  • Testing is a very important stage in app development.
  • This ensures overall quality of the application.
  • The cost can vary largely depending upon the number loops or the testing rounds required.

Few takeaways from Duolingo.

These are the few reasons why Duolingo is so successful:

  • The UI/UX is clean & perfectly placed.
  • The user is constantly assisted by the Duolingo owl, which helps the user navigate through the interface. 
  • The owl also acts as a visual motivator, for the positive & sweetly negative feedback it gives motivates the user to perform better & stay on track.
  • The learning process at Duolingo is highly interactive, & features like speaking tests take it to the next level for a holistic E-learning application.
  • A well strategized syllabus of every language makes Duolingo a complete application for beginners & intermediate learners.
  • Rewards & a constant track of progress motivates learners to “Do more”
  • The application feels more like a game & less like a boring educational application.

What can you do to stand out?

To stand-out from the competition you need to:

  • Integrate a real time chat box which is able to interact with the user in real time using AI, in more than one language.
  • Secondly & most importantly you need to integrate a flawless voice recognition system into the application.

“For you don’t want your application to fail in distinguishing between terms like ‘Sit’ & ‘S#it’.”

This also holds an opportunity for you as the voice recognition features of such applications are still far from perfect, and are still maturing with time & technology.

An application with a better voice recognition technology from the rest will not only help you stand out from the already existing competition, but it will also be a strong propelling force for your application’s overall popularity.


The right answer to the question “How Much Does Duolingo Like App Development Cost?” is “It depends.”

In the current time, a number of businesses and company owners are preferring to go online for conducting their businesses. Therefore, video calls have now become one of the most preferred means of work and business communication for various service providing companies.

Another major factor, which is responsible for the increased demand for video calls is “Work From Home,” which has changed the way of working flow completely. Due to this increased demand for video conferences, the competition in the market of video calling applications is at its peak. It is not at all an easy task to make an efficient video calling application that would become famous and gain high popularity among the users.

Hence, we need to follow some strategic steps in order to develop a powerful video calling application.

So, Let’s dive into it!

According to the research conducted by Statista, the maximum percentage of people using video conferencing mobile apps in the second quarter of this year falls under the age group of 16-24 years. It implies that the youth are more indulged in using video calling mobile applications. Also, the number of females of the same age group has been analyzed more as compared to the males. The following graph shows the global market shares of video conferencing app users on the basis of their gender and age.

What are the Top In-trend Video Calling Apps?

While planning to develop any competitive application, checking with the existing applications of the same category, analyzing the competitors, and looking at the leading marketers would be a wiser idea for developing user-centric and attention seeker applications. Here is the list of some big players in the context of video conferencing apps:


Zoom is famous for offering great video conferencing services to its users. This cloud-based service offering application has been gaining enormous popularity since 2020, and it seems that it will continue for many more years to come. As it is a very simple and efficient app with an amazing feature set and functionality, it is one of the preferred choices for business and education. Zoom offers free conferences for 40 minutes for up to 100 participants. For more viewers and calls, you will need to buy a plan.


FaceTime is another very popular video calling application among Apple users. FaceTime by Apple comes with an intuitive interface, which allows the users to initiate or receive calls from the app in a hassle-free way, from your notifications or contacts. FaceTime possesses a number of flawless features such as live photo capture, which helps you in taking pictures when you are on a call. FaceTime is restricted to Apple users only and you cannot make a FaceTime call to Android.


Skype is one of the most popular and oldest video calling platforms. This application is responsible for efficiently covering a number of devices and systems. Along with audio and video calling, Skype also features file sharing and text message sending facilities.

Microsoft Teams

Microsoft Teams is one of the most powerful and popular tools in the ecosystem of Office 365. It is responsible for providing engaging collaborative work features such as file sharing, collaborative editing, and calendar sharing. Recently, Microsoft has released Teams to use with a few limitations for free such as file storage. 

However, only those customers can access a full set of features who are using Office 365. The video conferencing feature offered by Teams is limited to four persons at a time only. However, if you are using it for personal or working purposes, Teams would be an ideal option.

Google Duo

Google Duo is another highly preferred and vital solution for Android users when it comes to choosing a video conferencing app. Google Duo possesses a user-friendly simple interface, supports various attractive features, and allows you to record video messages and send them. Hence, it makes connecting with your family and friends more hassle-free.

How to Create a Video Calling App?

If you want to build any robust, scalable, and user-centric application, the key strategy for the development of the app will always remain the same. Here is how you can build a video calling application that would have the maximum chances of getting success.

STEP 1: Analyze Your Target Audience

Analyzing and finding your target audience is the first step of the app development process. In the beginning, you must define the users who will use your product. What would be the preferred devices: Android, or iOS? You just need to ask these kinds of questions in order to get familiar with your audience before moving ahead in the application development process.

The following points will help you in analyzing the target audience for the development of your video conferencing application:

  • According to research conducted by Statista in the mid-year of 2021, the percentage of female users ranging between 16 to 24 years in age using video calling apps is 46%. On the other hand, 40% of males of the same age group are using these applications. On the basis of these statistics, we can see that the younger audience would be more appealing for the video conferencing app development.
  • You might also analyze for the interest of your target audience. For example, the younger audience would prefer various personalization features such as chatting stickers, a variety of filters, background modifications, and more. With these features, your app could play a vital role in reaching a wider audience.

Each industry such as education, communication, healthcare has its own needs and preferences that should be resolved and addressed efficiently. Therefore, analyzing your target audience is a very influential and primary part of a business plan for developing a video calling app.

STEP 2: Defining The Features And Values Of Your App

The next step after finding your audience is shortlisting the necessary features. We already made a list of chat app features that will be necessary for a successful chat solution. Some of them are easily applicable for a video chat app, but calls and the visual form of communication require additional functionality.

For example, in addition to general chat functionality, a video calling app should be able to create a video conference for more than two people, provide security for ongoing video and audio streams, and enable screen-sharing for collective work.

STEP 3: Creating a Business Plan

A business plan is responsible for defining all the essential elements of the app development process along with the entire product lifecycle. Some of the key factors that can help your business in formulating the plan are resources, vendors, audience segments, communication channels, partners, value, customer relationships, and the structure of total development cost for your video calling application.

STEP 4: Selecting the Right Platform

An important part of a business plan is choosing the right platform for your application. If web and desktop versions may pass without saying, a mobile platform can become a hard choice to make.

If you opt for Android, your app will be able to work on multiple devices, get to the largest app marketplace, and receive official Google support. However, there may be a chance of higher security risks and issues with testing and launching.

iOS offers you high security, good ecosystem optimization, and fewer devices for testing. Still, it can lead to platform inflexibility, a long review process, and limited customization.

Cross-platform is also available. You will cover all the possible audiences, but it will take more time and money.

STEP 5: Developing The Application

After successfully making the business plan, it is high time to start the process of developing an application. The entire video app developing process is not an easy task and includes a lot more along with the coding part.

So, let us start developing the app!

  • UI/UX Designing

The most crucial part of designing is prototyping. A prototype is a set of black and white screens (wireframes) that show all the main functionality of the app. It’s important not to underestimate this stage: prototyping will let you avoid mistakes in later stages of development, which will save a lot of time and money.

The user experience should always play the leading role in the designing process. This means that the app’s layout should be clear, understandable, and visually pleasing. Functions should not be confusing, and people with different technical backgrounds should be able to use the app.

  • Backend

With well-designed and tested wireframes and prototypes, it’s time to start working on the managing part of the app. You must first set up a server-side framework where the application will be created.

In short, you can build a video conference app using a custom backend and various tech tools, or you can choose a ready-made SaaS-solution. Our team works closely with PubNub and Twilio. Both companies provide services for building apps: PubNub has data-streaming software development kits and Twilio provides users with contact center solutions, WhatsApp APIs, and WebRTC SDK.

STEP 6: Testing of the App

The last step before release is to make sure your code functions as intended. Errors may appear in different parts of code and cause security issues or failure of some functions, and that is why QA matters.

Still, a perfect product launch is impossible. Final users will eventually find something that testers overlooked. Of course, developers will fix it after receiving real-user feedback. However, the fewer bugs and errors your first release version has, the better it is for building trust and loyalty with your audience.

STEP 7: Releasing of the App

When everything is finished, it’s time to make your app see the world. It’s important to know that the launch doesn’t mean the end of the work. Now you will have to keep your eyes on the audience and their reaction. Besides, it will be necessary to fix and update your video calling solution to support and increase its market position.

What Would be the Monetary Strategies After Creating a Video Calling App?

Monetary strategies play an important role in identifying the ways through which your video calling application can generate revenue. Along with understanding the technical stack required for the development of your app, the right financial planning is also a vital part of the success and growth of your business.

Some of the key financial strategies of a video chatting app are as follows:

  • Advertising – The core of that strategy is in-app advertisements that will make the app free for users. You can implement it either using PPC or working with brands. It’s possible to make money per view, per click, or per action.
  • Freemium – It proves itself to be the most effective monetization strategy. You can provide some basic functionality for free, and add paid additional functions, like using more sticker packs for chat, applying new backgrounds, or sending larger files.
  • Paid calls – This monetization strategy will add paid limits to calls. You can limit the times of calls and the maximum number of participants, and for additional time, users will have to pay.

What is the Video Calling App Development Cost?

The costs for a well-built solution will depend on several main factors like the team’s composition and rate, specifications of the app, and the expected deadlines. Usually, a video calling app requires the work of backend and frontend engineers, UI/UX designers, and QA specialists. Also, the project manager controls the process. Depending on the scope of work, the average costs for a video calling app will start from $70,000 and go higher.


We hope you will find this blog helpful. In this article, we have mentioned a step by step process of developing a successful video calling app along with its monetary strategies and current popularity. We have also concluded that developing a video calling app is not so difficult when compared to the previous few years looking at their current popularity across the world. So, go ahead and start developing your own video calling application, and very soon it will hit the market.

What is the Cost of Developing a Business Application?

In a nutshell, the total app development cost would range from $20,000 to $2,50,000 depending upon the complexity and features of the application. The development cost of an application also depends on its complexity.

Type of App DevelopmentEstimated CostEstimated Time
Simple App$39,000 – $65,0002 – 3 Months
Average App$65,000 – $1,45,0003 – 6 Months
Complex AppFrom $2,80,000More than 9 months

The above table shows the estimated time and cost (USA) required to build an app according to the type of its complexity. The cost of app development also depends upon the type of platforms such as iOS and Android, which are the top two platforms on which most mobile applications run.

Moreover, there are various companies that provide their cost calculators for the precise calculation of your application. Additionally, you are required to send your query with proper documentation that must contain:

  • The number of screens
  • The complexity type of your app
  • Developing process of the application
  • The complexity of the database and features
  • Implementation of various security protocols such as GDPR, HIPAA, etc.
  • Development team’s level and size

What is the Regional App Development Cost?

The cost of developing an application also depends on the region because different regions have different hourly rates for the development process of an app. This can be clarified further with the help of the table given below:

RegionsRate Per Hour (in USD)
India20 – 30
Eastern Europe30 – 50
Western Europe80 – 100

Here are some other factors contributing to the entire cost required to develop a successful business application:

1. Maintenance Cost of the App

Mobile apps also possess some maintenance cost similar to various software available in the market. On average, the maintenance cost of an app is roughly around 15 – 20% of the total development cost of a specific application.

2. Hosting Cost

The back-end data hosting of a mobile app is another important factor in the entire cost calculation of the app development process. It depends on the kind of data that your app possesses such as video, text, or audio. A mobile app with high media content would need more disk space, RAM, higher CPU, and more. Considering all these factors, your app hosting web server might cost between $70 – $300 per month approximately.

3. Monitoring of Mobile App

In order to make your app a successful one, one of the most essential steps is to monitor the performance of your app regularly. We all are aware of the fact that all mobile apps have a large number of users and a unique audience associated with them. So, it might not be feasible to get the accurate app monitoring cost. However, you can get in touch with various companies listed for app monitoring purposes and share your monitoring expenses with them.

4. Licenses Cost

The mobile app developers would need to pay the amount for a license if the design of their mobile applications includes payable technologies. In this way, it is also another factor contributing to the total cost of the app development process. A license fee depends on various factors such as the number of devices, annual fees to pay, and more. It might reach up to $110,000 annually for up to 50 devices.

5. App Releasing Cost

Releasing your app is the final step that we implement in the mobile app development process. It depends on the platform for which the app has been built. The Android apps will be released on Google Play Store and iOS apps will release on Apple App Store. Both these platforms possess different charges for publishing your mobile app. 

Google Play Store will cost you a one-time fee of $25. On the other hand, Apple App Store will charge you $99 per year. However, if the application is meant to be used within the organization then there will be no charges for Google Play Store, but, the Apple App Store will charge you $299 per year.


We hope you will find this complete guide to the app development cost quite helpful. In this article, we have concluded that businesses must keep in mind the factors involved in their app development process such as their location, complexity of the app, functionalities, and features of the app while estimating the entire mobile app development cost for their growth and success.

Additionally, as we have seen that the adoption rate for both Android and iOS platforms is high, therefore, choosing a mobile app for both platforms would be a smarter move that can help in enhancing the growth of your business. The best practice for that is to go with Minimum Viable Product (MVP) initially, which would be a cost-effective way. Another way is to go with Hybrid or Cross-Platform applications, which will also help you in reducing the entire app development cost.

Smartphones play a vital role in our day-to-day lives. This is the major reason behind many entrepreneurs and startups opting for mobile app development for almost everything. Most businesses and even retail or several other stores are using mobile apps for continuous engagement of their audiences. Which is why many individuals like you, are very anxious to launch their own mobile app.

Now, after the successful mobile app development, you might wonder, how to publish the app on the Play Store?

Well! This tutorial will help you step-wise to submit the application to the Google Play Store. This is because the Play Store is the most preferred platform in order to reach and engage a number of users.

So, let us hop in!

How To Submit An App To The Google Play Store?

Now, let us follow the below steps in order to publish your app on the Play Store. You must also ensure that you follow the right flow and process for hassle free and quicker publishing of the app.

STEP 1: Creating A Developer Account

In order to put an application on the Google Play Store, you must sign up for the Google Developer Account. There are four primitive steps that you need to follow for creating an account, which are as follows:

  • Go to the Google Developer Console by clicking on this link.
  • After this, sign up with the Google Account associated with you.
  • Now, accept the agreement for developers.
  • In this step, there will be a need to pay $25, which is a one time registration fee.
  • Now, complete the entire form by filling all the credentials of your account.

STEP 2: Creating A Google Wallet Merchant and Linking it to the Developer Account

Google Merchant and Developer Account Linking

In this step, you will need a merchant account in order to receive all the payments processed by the users for in-app purchases and downloading the app.

The following steps will help you in creating a Google Wallet Merchant, which are the must-follow steps prior publishing the application on the Google Play Store:

  • The first step involves logging into your Google Developer Account.
  • Go to “Menu” and click “Reports”.
  • After this, click on Financial Reports.
  • Now, select “Set Up a Merchant Account”.
  • Fill in your business credentials.
  • Finally, Click on the Submit button.

After clicking on “Submit”, your developer account will be linked to the merchant account.

STEP 3: Uploading The Application On The Google Play Store

After succeeding in the developer-merchant account linking process, you will get the access to upload the app on the Play Store.

The following steps will help you in creating a new app for App Store Listing:

  • Go to Menu, and click on All Applications.
  • Now, select “ Add a New Application”.
  • From the drop down menu, select the default language.
  • After this, name your application with less than 30 characters.

Now, here you will get two options to submit your application on the Play Store. Either you can prepare Store Listing or upload the Android Package Kit (APK).

STEP 4: Uploading APK or App Bundles

APK Files Upload

APK is the short form that we use for Android Package Kit, which is an Android file format responsible for storing, distributing, and installing applications on Android mobile devices.

There are two ways of uploading the APK. You can do this either by navigating and browsing or by drag-and-drop method into the box.

Follow the below steps to upload the APK file:

  • Go to Menu, and click “Release Management
  • Click on “App Releases
  • For the first release, select the release type from a closed test, production release, internal test, or an open test.
  • Now, you need to click on “Create Release

After following these steps, you will be required to follow the on-screen instructions in order to upload the APK files.

Important! If you have created an MVP (Minimum Viable Product) app and want to test it among a limited number of users, selecting from an internal test, open test, or closed test is the preferred way. On the other hand, if you are willing to test your application among mass audiences, then choosing Product Release is the recommended way.

STEP 5: Preparing App Store Listing

App Store Listing

In this step, you need to fill all the necessary information of your application in order to upload it on the Play Store. You can also save your form as a draft and complete it later. Also, do not forget to get in touch with your branding or marketing team for creating the perfect app profile as per the requirements of your business.

The following steps will help you in creating the appropriate app profile:

  • First, add the title of your applications, which must be less than 50 characters.
  • Then, add a short description for the app, which should not exceed 80 characters.
  • Now, add a full description for the app within 4000 characters.
  • Also, do not forget to add the screenshots, videos, graphic content, icons, and images of your application.
  • Add the app translations in different languages. Either you can purchase them or add your own version.
  • Ensure relevant category and type for the categorization of your application.
  • Add your correct contact details for quick contactability of the users. Including the email address is mandatory. However, adding your website and phone number is your choice.

From the user’s perspective, the informational detail that you will enter is responsible for creating the persona of the application. It plays an important role by helping the user in deciding if they should download the app. So, you must fill this information carefully.

STEP 6: Adding the Correct Content Rating

Content Rating

If you skip rating the content correctly, there is a high probability of getting your app removed from the Play Store. Follow the below steps to rate your content:

  • Go to Google Play Console
  • Now, go to Menu, and click “Store Presence
  • Now, you can rate from here.

The rating plays an impeccable role in engaging a large number of relevant users to the application. However, make sure that you provide the right rating and accurate information. This is because, providing the false rating or misguiding the users might end in getting the application removed or suspended from the Play Store.

Just a few more steps and you will be able to efficiently publish your app to the Google Play Store!

STEP 7: Selecting a Distribution and Pricing Model

Pricing and Distribution Model

Now, in this step you will get two options to publish the app. Either choose the paid version or free version of the app to be published. One thing is to make sure that Google Play Store only allows you to change the paid version of an app to the free version after publishing. Which means, if you have submitted the app with its free version, you will not be able to change its version to free after that. So, when it comes to choosing the pricing model, be careful!

Now that you have wisely selected the pricing model, let us quickly discuss the selection process of the distribution model.

Here you can either choose the preferred specific countries or choose all countries for the distribution of the application. Also, you can select specific Android devices and programs for the application.

STEP 8: Publishing the App on Google Play Store

Publishing Your App

This step primarily deals with the reviewing and cross checking of all the above processes that you have gone through. Make sure that you have not missed a single step and completed the process accurately before you finally click the “Publish Your App” button.

Here you will get the information about any missed information, errors, or any other warnings that may cause interruption in the app publishing process. Just go through and review all the necessary information carefully and wisely.

Alas! You have successfully published the app in all the selected countries.

After following the above steps carefully and publishing the app on the Play Store, it is high time to think about how to make the app popular and get it featured. Some practices can help you in getting your app featured on the Google Play Store such as working on the recently launched or trendy technologies, visual designing, localization, and more such.

Getting your app featured can provide various benefits to the application and helps in increasing the number of users to the application in numerous ways.

What Necessary Steps You Should Follow After Submitting The App?

Right after submitting the app to the Play Store, you might wonder, What next?

Well! We have come up with this solution as well.

You can involve in practicing the following steps in order to make your app globally attractive and user-centric:

  • Promoting Your App

In order to quickly make your application popular, there is no other medium as fast as Social Media. According to a research conducted by Global WebIndex in October 2021, more than 57% of the world’s population is involved in Social Media, and these stats easily explain the power of Social Media. Some of the most popular Social Media platforms are Instagram, Pinterest, Facebook, and more. In this way, if you promote your app on these platforms, the chances of more downloads and user engagement will efficiently increase.

  • Practice App Update and Maintenance

After publishing the app, there is a need to update and maintain your application consistently for the betterment of the app. By fixing several bugs and issues and implementing regular updates will efficiently help you in keeping your app healthy and maintained.

What Is The Total Time That An App Takes To Publish?

The time required to publish an app on the Google Play Store is not fixed. Although the app publishing process through Play Store Console is quicker and easier, the time duration required by the app to get selected and reviewed varies. It can take from hours to a few days. This means after publishing the application, you should wait patiently for some time.

How Much Is The Cost For Publishing An App To Google Play Store?

The cost of putting an application to the Play Store is $25, which is a one time registration fee that you need to pay for the first time while publishing the app. After this, all the apps that you will submit to the Play Store will be free of cost.


We hope our article will help you in submitting an Android app to the Google Play Store by following all the mentioned app publishing steps in the correct flow. After uploading the app successfully, you should plan about the maintenance and upgrades of your app, which is a wise practice to keep your app live on the Google Play Store.

What is Android OS? 

Android is an electronic mobile device operating system used for smartphones, tablets, smartwatches. It is based on the modified version of the Linux kernel and other open-source software. The android operating system was built by an association of developers and software designers collectively known as Open Handset Alliance and financed by Google. Android is a free and open-source operating system.  

What is Android App Development? 

Android app development is the procedure of building applications for mobile devices that has android as the operating system. Android apps can be developed in Kotlin, Java, and C++ programming language using Android SDK or can be developed with the help of the software tool Android Studio. And after developing the application it’ll be launched on the Google Play Store for users to use. To develop the applications in non-JVM (Java Virtual Machine) languages need the JVM-language code. 

Android Mobile App Development Techniques 

As the technical world is ever-changing, new techniques, new tools, new frameworks being developed every now and then. So based on the recent advancement, there are two android app development techniques  – 

Hybrid App Development 

Hybrid app development is the technique where a single app is built for and run on multiple operating systems like Windows, Android, and iOS. Mobile applications developed by using the hybrid technique can have different UI for different platforms and also can exhibit different features but the core idea and purpose of the application remain the same. It follows the mantra of  “write once run anywhere”. 

Native App Development 

Native app development is a technique where an application is developed for the specific operating system for particular mobile devices. Native apps are developed either for Android or iOS or Windows.

Android App Development

Android App Development Frameworks 

An Android application development framework is a software toolbox that empowers application engineers to bits together with a completed item that meets the prerequisites of its owner. A system gives the bones of an application, to be fleshed out with illustrations, movement, unique highlights, and usefulness. Application structures are intended to rearrange the application advancement interaction and make it simple to oversee, adjust and fix bugs as it were. 

Android application development company share large numbers of similar properties, alongside exceptional highlights that improve their fit to particular kinds of undertakings. The application system you select ought to be picked with the particular necessities of your venture at the top of the priority list.

React Native 

React Native is an open-source framework for more desirable mobile application development with extensions to web application development as well. It was published by Facebook in March 2015. React Native is one of the most popular and commonly used cross-platform mobile application development frameworks nowadays. It is used from Android to the development of iOS applications, to Web applications, and even for UWP (Universal Windows Platform).


Flutter as we all know is an open-source software development kit developed and launched by Google. It uses for the development of Android, iOS, Windows, Mac, Linux, Google Fuchsia, and web applications. It allows cross-platform development.


Native Android development framework is among a portion of the world’s most famous versatile mobile app development framework. The SDK furnishes engineers with API libraries and developer tools important to fabricate, test, and troubleshoot splendid applications for the Android Platform.


Established in 2012, Ionic is viewed as perhaps the most famous cross-stage advancement system. It is a free, open-source system ensured by MIT that permits designers to utilize current web innovations including HTML5, CSS3, and JavaScript.

Android App Development Programming Languages 

A programming language is a computer language containing a set of strings, variables, and other data types that when put to get in a specific format with the right syntax and semantics it’ll give you a code that will be complied further give you an output.  In simpler words, the programming language is nothing but a language to give instructions to a computer. 


Java is a high-level, classes-based, object-oriented computer programming language. Java was developed to have lower implementation dependencies.

Java is a bit complex language and yet it is the most used programming language for Android App development. The mobile applications as simple as a calculator to some complex applications like canvas designing app, Java has answers for everything. It supports the hybrid(cross-platform) development technique to coordinate REST APIs in the application. Custom UI development and designing are completely supported by Java.  

Google APIs linked with maps, advertisements, or firebase (cloud database), can be flawlessly coordinated with Java. The more perplexing the application features are, the simpler it is to create in Java. Abilities mastery is expected to develop the application. Once the application design is fabricated, it is helpful to utilize Java to assemble the work process in the application. Java is known for both hybrid and native android app development.

Android applications developed on Java – Uber, Trello, etc. 


Kotlin is a cross-platform i.e. can be used for different operating systems, general-purpose computer programming language. The main reason for developing Kotlin is to have a language that can be fully interoperable with Java. 

On 7 May 2019, Kotlin was officially adapted by Google for Android app development. Since then the Kotlin library was being used as a module for Android SDK.  In terms of UI, Kotlin definitely proves to be better. Kotlin is known for designing an amazing user interface. Back-end programming for applications developed in Kotlin language is not an issue because it works in coordination with Java APIs. Kotlin is good with providing expansion highlights to make it easy for the demands.  Kotlin is the language that is being purely used for Native app development only. 

Android applications developed on Kotlin – Pinterest, Basecamp3, etc. 


C++ is a general-purpose computer programming language invented by Bjarne Stroustrup. It follows the OOPS (Object-Oriented Programming Structure) paradigm and is an extension of  ‘C’. C++ is also referred to as C with classes. 

If your application includes working on complex logic related to token validation or either you want your application’s back-end logic to be fully secure that no one can decipher it then, C and C++ are the answer to your prayers. C and C++ code can be used with Android Native Development Kit. For the android applications that need to be developed with a lot of computational algorithms and logic or artificial work, you can use C++ libraries. The native C and C++ libraries are known for high-speed performance and they take low reaction time between activities.  C++ can’t be used for cross-platform app development. 

Android applications developed on C++ – YouTube, Amazon android app, etc. 


JavaScript (JS) is a computer programming language that follows the ECMA Script specification. JS is a high-level, just-in-time (JIT) complied and multiparadigm language. In all honesty,  JavaScript is the number language for web development. The ascent of frameworks like jQuery, Angular, Vue, Svelte, and React.js has made JavaScript significantly more mainstream. 

React Native, a famous JavaScript framework permits you to foster cross-platform applications for both Android and iOS portable. We suggest you pick JavaScript for its all-inclusive allure and fame. And if you’re eventually planning to shift to iOS JavaScript should be your go-to language. 

Android applications developed on JavaScript – LinkedIn, Candy Crush, etc. 


Dart is a software development language, which was designed with the sole purpose of designing web, desktop, and mobile apps. It was invented by Google. It is an object-oriented, class-based language that follows the ‘C’ syntax style. 

Dart is the language associated with the Flutter framework developed by Google. Flutter was invented with the goal of better cross-platform app development. By using Flutter the developers can’t develop only singular operating system mobile apps but for both the platforms as well as web applications that too using a single codebase. Dart and Flutter are free and open-source for developers.  

Android applications developed on Dart – Alibaba, Google Ads, etc. 


C# is another general-purpose, multi-paradigm language. It is also an updated version of ‘C’ with lots of new features. It comprises static typing, lexically scoped, in-built functions, object-oriented, and also component-oriented programming instructions. 

C# is quite similar to Java with all its object-oriented properties even a little because it has component-based properties as well. In terms of syntax and in-built functions, no doubt C# is better than Java which makes coding a lot easier and hustles free. C# is used with the .NET framework which comes with its own benefits. 

Android applications developed on C# –FareBoom, Slack, etc. 


With 2 billion Android mobile phones out there in the world, no time is best than now to conquer mobile app development

There are a ton of applications like Chat Messenger, Music players, Games, and so forth that can be made utilizing the above dialects. Also, there is no language that can be known as the “right language” for Android App Development. Thus, it’s upon you to settle on the right decision of language based on your goals and inclinations for every individual venture. What’s more, consistently recollect, whatever your decision, it will just extend your range of abilities and lead to your development as an Android developer.

What are the Native Apps?

Native applications are mobile applications (as matter of fact applications for every smart electronic device with an operating system ) for the specific operating system based mobile devices (well in this article we are going to stick to the native mobile app development) and are installed on the device through the dedicated app store ( for android Google Play Store and for iOS App Store) without any hustle-bustle of downloading the applications through a browser and then installing them.  

What is the Native Mobile App Development?

Native mobile app development is creating a mobile application solely for the targeted operating system. Mobile app development will only be possible with dedicated programming languages and tools that are meant for the particular platform. For example, for Android app development Kotlin and Java are your go-to languages, and Android Studio is your tool. And likewise, for iPhone app development, you can use either Swift or Objective-C and the best tool will be Xcode

Benefits of Native App Development 

  • Native app development provides broad functionalities. 
  • It is faster and provides more responsive software performance. 
  • Better for providing push notifications. 
  • Provides better User Interface with great UE (user experience) because Native app development is operating system specified. 
  • Provides more security in comparison to other types of applications because it’s particularly built for one type of platform. 
  • It definitely provides better store support for the applications and faster and better updates. 
  • Native apps have top-notch functionality and better access to hardware and other operating system-specified tools. 

Drawbacks of Native App Development 

  • Costly, no matter how amazing native apps are they are definitely not cost-effective. 
  • Time-consuming. Nowadays, every person, every business doesn’t only want one type of mobile application. So obviously, building both Android and iOS applications it’s pretty time-consuming. 
  • No one codes. As a developer, you have to write code for both operating systems.

How to Develop Native Mobile App

I wrote this one for beginners who are not well-aware of the tools but do know a little bit of Java, Objective-C, or swift but want to try their hand at android app development or iPhone app development. If you’re looking for easier ways to learn native mobile app development, this article is for you all.

How to Develop an Android App

This one is for the beginners level who are not well-aware of the android studio but do know a little bit of Java. but want to try their hand at android app development. If you’re looking for simpler techniques to learn native mobile app development, you are at the right place.

First Step

  • Download and install Android Studio
  • Launch the Android Studio on your system.
Native Mobile App Development

  • At the very first page of the Android Studio, select and click on ‘Start a New Android Studio Project’.
Native Mobile App Development

  • Then, it’ll direct you to an ‘Activity’  page, here select  ‘Basic Activity’ and click Next.
Native Mobile App Development

  • This will take you to the ‘Configure Your Project’ page, which contains basic information about your first Android app. On this page, you can rename your first application as per your choice.
Native Mobile App Development

  • Make a note of the ‘Save location’ just in a case scenario when you need to locate it. 
  • The language chosen should be ‘Java’, but if you’re aware of Kotlin that will be fine as well. 
  • Click on Finish.

After the background processing, it’ll take you to the main window of your Android project. There will be two tabs available on the right-hand side –

  1. Activity_main.xml – this is the visual representation of how your application’s main screen will look like. Here, you can drag and drop the buttons, text-box, text-view (the text that’ll be visible on screen), password-bar whatsoever you need without being worried about the coding. 
  2. MainActivity.java – is purely about the coding. Here, you’ll punch the code lines about the functions of the tools that you have dragged and dropped and what exactly your main screen of the application will do.
Native Mobile App Development

Second Step

Examine the project structure and the layouts available. Make yourself aware of the things and features that are available at your fingertips.

Third Step

The utmost important step for executing and testing your application is you have the device to test-run the application. There are two ways – 

  • Run it on the real device 
    1. Connect your smartphone to your system with a USB cable. There are chances that the required USB driver won’t be available on your device. Make sure you check it. 
    2. Start USB debugging into Developer Mode window
      • Open Settings on your smartphone. 
      • Scroll to the end or either search About Phone.
      • Go to Build Number and tap seven times. 
      • After that, come back to the main settings and scroll down to find Developer Options
      • In the Developer Options screen look for USB Debugging and enable it. 
    3. Select the android app developed by you, that you want to test-run. 
    4. In the toolbar, select the desired device you want to run your application on. 
    5. Then click on the Run button, on the right-hand side of the toolbar.
Native Mobile App Development

  • Run it on Emulator 
    1. Firstly, you need to create an Android Virtual Device (AVD) that can be later on used by the emulator for the execution of the android app. 
    2. Open the android app developed by you that you wanted to test run. 
    3. On the toolbar, from the drop-down box for the targeted device choose the Virtual Device you want to execute the application on. 
    4. Then click on the Run button, on the right-hand side of the toolbar.
Native Mobile App Development

Fourth Step

This one is about using the .xml file. Working on the layout of your application, how it’ll look like and what features you want to use. All you have to do is drag and drop the snippets you want in your application. You can use TextView – to show a fixed Text on your application like “Welcome”.  After choosing the snippets arrange them and resize them as per your need. After completing this, click on Run to have a virtual representation of how it’s going to look.

Native Mobile App Development

Fifth Step

Your snippets still don’t work, to make them function you have to open the .java tab and start punching in the code. Write the code for what you want your TextView to show and how you want your button to work.  To show the progress of your application when you click the button, add a new Activity. This new Activity will show the progress, you can keep it simple with only a welcome message or can display the name of the Native mobile app developed by you. Click on Run, for the test run.

Following these steps, your first android application is up and running. In case of further assistance, feel free to drop a comment.

How to Develop an iOS App

This one is for the beginners who are not well-aware of the Xcode but do know a little bit of Swift or Objective-C but want to try their hand at iPhone app development. This article walks you through the basic steps to develop a simple iOS application.

Step One

Download and install Xcode on your Mac and if you’re a Windows user you can use Flutter for the iPhone app development.

Step Two

  • Launch Xcode. And select ‘Create a New Xcode Project’.
Native Mobile App Development

  • Select App and click Next.
Native Mobile App Development

  • The next step will be naming your iOS application.
Native Mobile App Development

  • To select the language, choose the one you’re well-versed with. 
  • Make a note of the ‘Save location’ just in a case scenario when you need to locate it. 
  • Click on Next.

Step Three

Choose the folder you want to save your project in.

Native Mobile App Development

Step Four

Examine the project structure and the layouts available. Make yourself aware of the things and features that are available at your fingertips.

Native Mobile App Development

Step Five

After selecting the folder, and exploring the software. You can punch in the code, the basic code maybe something like “Hello World” and try to execute, just to make sure your Gradle is built successfully and giving you the desired output.

Native Mobile App Development

Step Six

After running the basic program and getting the satisfactory output you can start writing the code for your desired application. And if you are stuck anywhere, you can always refer to the in-built Xcode guide that will explain the working and usage of the functions. You can always test run your applications to see how the output will.

Step Seven

You can always have a visual representation of how your iOS application will look. During the 2.3 steps mentioned early right below the language option, there’s another drop-down for selecting User Interface. If you go ahead and select the Storyboard, it’ll give you the virtual stimulation of how an iPhone app developed by you will look like. Storyboards have drag and drop options where you can drag and drop the snippets, text boxes, buttons whatever you want to use on the screen of your virtual phone. On the right-side panel, you can change the size and the text on the snippets as per your wish.

This is how the storyboard demonstration will look. You can drag and drop whatever snippet you want. 

This raises an important question – 

What to choose between Storyboard and SwiftUI? 

As a beginner, I personally recommend you to go for Storyboard because it gives you a virtual representation and definitely simpler and easy to use because of the drag and drop facility. But if you’re well-versed with the Swift coding and won’t mind resolving a few errors then you can definitely go for SwiftUI. 

Wrap Up 

This article gives you an insight into native app development and native applications as well. Through this one, I tried to give you basic knowledge about native mobile app development and how to build basic, beginners’ level Android and iOS applications.

This article will help you in understanding the basics of developing Android apps using the Android Studio development environment. Since Android devices are enormously increasing, the demand for Android new apps will also increase. Android Studio is a free and easy to use development environment to learn. If you have a working knowledge of the Java programming language, you will find this tutorial more helpful as Java is the programming language that is used by Android.

What is a Mobile Application?

Mobile application or mobile app is a computer program or software program that is developed for mobile devices, not just phones but also for tablets or smartwatches. Mobile applications were basically developed for essential assistance and productive services like calendar, emails, or contacts the things a person needs handy. But over the years, with the raising in the number of mobile phone users the type of mobile applications also rapidly grow like there are now social media applications, mobile games, etc.

Nowadays there are applications available for every purpose, you want to track your steps – download the application, want to read books why bother to go to market – you can read it on your application all you have to get the application.

In fact, the famous American technology columnist and writer David Pouge renamed smartphones as app phones to distinguish between the earlier smartphones with lesser applications to the modern-day phones available with millions of applications.

Android – The Wonderful Operating System

Android is an open-source mobile Operating System developed by Android Inc. which was before the release of the OS, it was taken over by Google. It is developed on a modified version of Linux and a few other open-source software. It was solely meant for mobile app development but now it has taken over the market for applications on wearable devices and smart TVs as well.

What are the Steps for Developing A Basic Android Application?

1. Install Android Studio

The first step is pretty obvious, to develop android application first step should be to Install Android Studio. While downloading one needs to make sure that it is from Android’s original site and all the requirements for hardware and software meet.

2. Download Java Development Kit (JDK)

Make sure you have JDK installed in your system for Java. If not, go ahead and install it. If you already have you’re good to go ahead. 

3. Opt for new Project

When the setup is done choose ‘Start a new Android Studio Project’. Choose a name that will appear at the store for your application and a ‘domain’ for your company if you’re acting as an individual you can choose something else but decent. This is how it’ll appear: com.companyname.appname. This represents the APK (‘Android Package File’) that will be uploaded to the Google Play Store.

4. Choose an Activity

The next step will be about choosing how you want your application to look like. The first ‘Activity’ you choose will represent your application’s main screen. There are various modules available at Android Studio, you have to choose according to the need and the idea of your application. There are full-screen activity, blank activity, etc. But as for the beginners, it’s better to go for ‘Basic Activity’ to keep things simple. Make sure the selected language is Java and not KOTLIN.

5. Choose the desired Layout

After choosing the required activity, comes the part to select a layout name for the chosen activity. The layout will define where the elements like images and menus go and what fonts will be used and visible to the end-users.

6. Edit the textbox according to your requirement

The next step will be about editing, moving, stretching the textbox and other available widgets as per your plan and your applications. When you choose a widget that comes with the default texts, you need to edit the texts, the size, the colour as per your plan of the application.

7. Add buttons and widgets as per your and application’s need

This step is about drag and drop of all the widgets and buttons you need in your application, and renaming them, editing them, adjusting them.

8. Code for the Backend

Here, comes a bit of a complex part that is the backend coding. You need to fill in the details of all the widgets you use with their respective functions. And you have to write a code for what your application will do.  Android Studio provides code suggestions, so you don’t have to worry much about it.

9. Test Run on Emulator or connected Android Device

The last step is always about execution. After you think your application is ready, test it to make sure it’s working the way you have planned.


We hope you will find this tutorial helpful as this guide is to help first-time developers so that they can develop their android applications without any complications. You have numerous opportunities to make your “dream app” come true.

Swift vs Kotlin

Swift vs Kotlin: What is the Difference?

Kotlin and Swift programming languages are the development languages for Android and iOS platforms respectively. Both these languages play a vital role in giving the functional feel to the world of mobile app development. Although the predecessors of Kotlin and Swift, Java and Objective-C, are object-oriented, these development languages provide the mobile app  developers, like you,  with an Object-oriented paradigm in a combination with some impeccable functional features.

Kotlin is a programming language used for Android app development whereas Swift is used for iPhone application development. Both Kotlin and Swift are built on top of the modern programming approach and software design pattern. Both languages provide several inbuilt functions defined in an extensive list of libraries and amazing features to the mobile app development companies.

5. Conclusion


Kotlin and Swift programming languages were designed in order to interop with Java and Objective-C allowing for advanced and latest updates in applications to be significantly written in these languages.

In this article, we have discussed the differences between the most popular mobile app development languages; Swift and Kotlin.

What is Swift?

Swift is a multi-paradigm, compiled programming language invented by Apple for its own operating systems to make it easy for Apple devices. iOS, iPadOS, tvOS, Apple smart wear operating system, and every other device. In short, Swift is a language for developing all the applications on all Apple devices.

Swift was inspired by Objective-C, C#. Swift was mainly developed to work with Apple’s Cocoa and Cocoa Touch. Swift has amazing features to address common but problematic programming errors smoothly. Swift can be executed with C, C++, and Objective-C in the same program. Swift is the best language for mobile app development for iOS.

What is Kotlin?

Kotlin was developed by JetBrains and Google. Kotlin is a cross-platform, statically-typed general-purpose language with a type interface. Kotlin is mainly focused on mobile app development but it can also be used for web app development instead of JavaScript. The main reason to develop Kotlin was to have a language that’ll be interoperable with Java and the JVM version of its standard library. Kotlin is inspired by C#, Groovy, Java, and Python.

What are the Differences Between Swift and Kotlin?

Swift vs Kotlin – Purpose of Development

Swift was built for iPhone app development, whereas Kotlin was for android app development.  Apart from the purpose of development they both have very different syntax and features for mobile app development.

Swift vs Kotlin – Differences in the Language Norms


  • Swift “Enums” are more effective.
  • Swift uses no data class.
  • Swift does not support delegated classes or delegated properties.
  • Swift has no provision for annotations.


  • All Kotlin classes are “final” by default, the developer has to use a specifier as per the need.
  • Kotlin does not support struct or passing data by value.
  • Kotlin uses no tuples.
  • Kotlin doesn’t support type aliases.
  • Kotlin doesn’t have a guard statement.

Swift vs Kotlin – Memory Management

Swift uses ARC or Automatic Reference Counting for memory management. Kotlin uses the Garbage Collection memory management approach.

Swift vs Kotlin – Interoperability

Kotlin code is interoperable with Java, the sole reason to develop Kotlin is to have an interoperable language with Java. Java and Kotlin classes can be in the same file and the application will run smoothly. Likewise, Swift coexists with Objective-C code.

Swift vs Kotlin – Function Implementation


func patientDetail(_patientName:String, _city:String):


return “The Name of the Patient is \(PatientName) and city is \(city)”


patientDetail(“David”,” CA”)


fun patientDetail(patientName:String, city:String):

return “The Name of the Patient is $patientName and city is $city”


empDetail(“David”,” CA”)

Swift vs Kotlin – Which should you choose?

Swift or Kotlion, which development language is right for you? Well! Both the programming languages are modern when it comes to mobile app development. Swift and Kotlin both make writing code hassle-free and easier than the legacy languages used for iOS and Android app development.

your decision must depend on the type of mobile platforms you would like to develop the application for. With Kotlin, you will be able to build Android apps. And with Swift, you will be able to build applications for iPhone and Mac OSX development.


We hope you will find this article helpful. After going through this article, you will understand that like always there are both similarities and differences between the two languages. Both Kotlin and Swift are evolving in terms of performance, programming advancement, and security. As both languages have their own perks but they both are great in their own ways like Kotlin for Android and Swift for iOS.
