Top 10 App Development Languages

The use of smartphones is globally increasing among people from all walks of life. A survey of Statista reports there are 6378 million international smartphone subscriptions in 2021.

This report also reveals that this amount would reach 7516 million subscriptions by 2026. This trend also leads towards more utilization of applications. But to create such applications, the selection of app development languages is becoming challenging for businesses and developers.

That is why this article is going to discuss the best app development languages. Moreover, this guide categorises mobile applications into distinct types and discusses the best languages for different kinds of mobile application platforms.

Key Takeaways

  • Java, Kotlin, and Lua are usual technologies for Android apps
  • Swift and Objective are the best choices for iOS apps
  • Ionic and React are great for PWA development

Types of Mobile App Development

Here are the 4 major ways you can develop mobile applications:

Native Android

Android is radically a mobile operating system. Basically, this is an advanced version of the Linux kernel that was initially released in 2008 for touchscreen gadgets, including tablets and smartphones. The applications that are launched on this platform are known as Android applications.

The Q1 2021 survey report of Statista Research Department discloses that around 3.48 million Android applications are available on Google Play. Moreover, if we talk about the best Android app development languages, then Java, C++, Lua, and Kotlin are prominent.

Here are the core advantages of app development with Android:

  • The app development with Android OS is quick, but its fast app building, testing, and launching cycle also reduce the time to market (TTM). So, app development with Android is beneficial for businesses that want to overcome their app-building duration and fasten their go-to-market (GTM) approach.
  • Android app development also confers great versatility to its users. Indeed, it is seamless to target smartphones, wearables, desktops and tablets with your Android applications. Developers can also easily integrate their Android applications with the internet of things (IoT), virtual reality (VR) and augmented reality (AR) functionalities.
  • Another major advantage of using Android for app development is its good ROI. Surely, it is uncomplicated to access Android SDKs, and businesses can create interactive applications with less cost and time. In addition, Android platforms like Google Play Store only ask for a one-time payment option when you need to launch an application.
  • In the same token, app development with Android comes with superlative customization properties. Android applications are infused with numerous advanced functionalities and multimedia tools.
  • Security has become a primary concern for both enterprises and developers. So, if you want to make highly secure mobile applications, then Android could be a great choice for you. Likewise, anti-tamper tools, limited access, transit data protection and several other built-in app safety features in Android are very beneficial to improve app security.

Native iOS

iOS is another mobile platform that was initially launched in 2007 by Apple with the name of iPhone OS. It holds 26.35% market shares, according to the recent data reports of StatCounter.

This operating system usually covers Apple devices, including iPhone, Apple TV, iPod, Mac, Apple Watch and iPad etc. All applications that are designed to launch on the iOS mobile computing platform are known as iOS apps.

Statista Research Department shares around 2.22 million iOS applications are available to download on Apple Store according to Q1 2021. This figure also makes iOS the second most used app development platform.

Here are the main benefits of iOS app development:

  • The best thing about making an app with iOS is its classic testing practice. It is quick and simple to test your application with iOS because there are only a finite number of iOS devices and versions available in the market. So, you can fasten your testing process.
  • Moreover, big enterprises prefer to go with iOS app development because iOS applications confer great security features. Yes, both Apple devices and OS grants security layers against data breach, malware, phishing and hacking threats. This is also a reason that enhances the loyalty of iOS app users.
  • iOS applications are considered very good when it comes to performance. Definitely, an amazing merger of software and hardware supports iOS applications to maintain their performance. This benefit also leads to customer loyalty.
  • On the other hand, if your target audience is from the United States and Europe, you should prefer to go with iOS app development. It has been noticed that people of the UK, Germany, USA and France still believe a lot in Apple’s smart devices.

Progressive Web Application (PWA)

PWA technologies are basically web applications that utilize properties of progressive enhancement approach and web APIs to confer user experience similar to a native app.

Businesses can run progressive web applications on all platforms with improved user experience features.

PWA is known because of its fascinating benefits. We are also presenting the major ones here:

  • PWA applications are considered the most responsive ones. They can work on any device, screen size or browser because of their flexible user interface.
  • It is also easy to find such applications on search engines because of their web app properties. Therefore, people who prefer to use search engines to find products or services can easily access PWA applications.
  • Do you think PWAs are only web or desktop applications, and you can’t install them on mobile devices? If yes, then you are wrong. Another great advantage of using PWA is it’s easy to install characteristics. Luckily, you can install PWAs and can also access them when you are offline.
  • PWAs are also famous because of their fast load time speed. By using PWA technologies, companies enhanced its page speed to 38 percent.
  • Appealing application icons, low development cost and push notification features are also some advantages of using PWAs.


Cross-platform app development is an approach that allows coders to develop a single application for multiple platforms. Yes, cross-platform applications could be run on multiple app platforms or operating systems rather than building separate versions for each OS.

Flutter, Xamarin, Ionic, and React Native are some of the ideal app development languages for cross-platform that businesses can consider using.

Here are the primary advantages of Cross-platform app development:

  • With cross-platform app development, you can spontaneously launch your application on different app platforms such as iOS, web and Android. This quick launch doesn’t only overcome your app development duration but also reduces the development charges.
  • Similarly, cross-platform development permits businesses to target a large audience because their single app version works on all operating systems and devices.
  • Furthermore, cross-platform technology also confers automatic updates that is a great relief for users who don’t like downloading app updates after a few days. The maintenance of such applications is also easy and quick.

Open-Source — Like many other programming languages, Swift is also open-source. You can easily find bug trackers, solutions to fix errors and forums to discuss your app development issues.

5. Objective-C

Objective-C is a general-purpose programming language that follows the paradigm of object-oriented programming. Objective-C was the standard language for the development of macOS & iOS operating systems by Apple.

This programming language is majorly used in iOS applications development.

Core Features of Objective-C

Object-Orientation — Object-Oriented programming paradigm is the most famous paradigm in the world of programming. It helps the developers in implementing solutions to real-time problems. The code is more structured and easier to read when it is object-oriented. The re-usability of code increases with the use of class and object orientation.

Error Objects — Error Objects can be used in Objective-C programming language to handle the exceptions. The exceptions that occur at runtime can be handled easily with Error Objects in Objective-C.

Data Types — Variable data types need to be defined at the time of declaration so users can store specific data in specific variables. It makes the code more understandable and manageable. Different types of variables do not let the data get manipulated easily.
