Which language should you choose to develop your mobile application?

No one doubts that mobile applications and programming languages ​​are the future of development. Gone are the days when companies could ignore mobile users!
If you are just starting to build your application, you need to choose the right technology and the right programming language.
There are dozens of programming languages ​​for mobile apps. Reviewing lists of 30 different languages ​​on one site, then looking at 15 on another site can take a few days…
To save you time, here is a list of top 5 languages, each of which will help you develop a mobile app.

Why specialize in mobile development language?

Developing a mobile application requires a lot of time and money. If you’re planning on building a mobile application for Android, iOS, or both, you’ll need to decide which programming language you’ll use.

If you’re not sure which language to choose, check out our guide to the most used programming languages ​​in the world today. This can help you choose the best one for your business.

The first step is to identify what kind of application you want to build. Will it be for internal process? Or will it be for public consumption? Will it be a simple app that just needs to get the job done, or a complex app with lots of features?

Once you know what type of app you need, it’s time to start looking for languages. You need to consider three things: ease of use, market penetration and popularity, and flexibility.

Specializing in a mobile development language will allow you to build apps for specific platforms, devices, operating systems, and screen sizes. For example :

  • If you want to build apps for Apple iPhone or iPad devices, you’ll need to learn Objective-C.
  • If you want to develop Android applications, Java is the best choice.

There are different types of app development from a coding perspective. In general, mobile application developers can build applications in one of these 2 categories: native or hybrid applications.

native apps

Native apps are coded in a language that is natively supported by the operating system of a specific device.

Of course, if you want to code your app “natively”, you really need to build 2 apps altogether.

Java (Android)

Java is over 25 years old and remains the most popular programming language among developers, despite all the new ones coming out in recent years. In a world where new technologies are rapidly replacing the old, no one has been able to replace Java.

One of the main reasons why Java is the first choice among application developers is that it is very easy to learn and use, and it also has a huge community, which is a welcome help for new developers.
Despite its ease of learning, Java is a very powerful programming language for mobile applications.

Some of the best Android apps are developed using Java, including Spotify or Twitter. The Android operating system is also coded in Java.

Kotlin (Android)


Kotlin is a statically typed programming language for the Java Virtual Machine (JVM) and Android. It was designed by JetBrains to be a better Java and has some really killer features.

The main thing is that it is compatible with all existing JVM tools, libraries and frameworks, which means you can use it from day one without learning anything new or changing your workflow. If you want, you can also write your Android apps in Kotlin.

Kotlin also has other interesting features:

  • Intuitive syntax that lets you code faster and more efficiently than in Java.
  • A robust type system that helps prevent errors and provides many useful features such as null protection and data classes.
  • The Null annotation allows you to specify which variables can be null or non-nullable when declared. So you don’t need to worry about runtime exceptions caused by forgetting this important detail while coding.

It provides an extremely convenient way to write code in your mobile apps. Kotlin is fully interoperable with Java (one of the most popular programming languages)Which allows developers who have worked with Java in the past to start using Kotlin in their projects.

Kotlin also comes with great IDE support, making it easy to develop your apps with Kotlin.

In applications coded with Kotlin, we refer to Trello, or Evernote.

Swift (iOS)


The successor to Objective-C, Swift is an open-source programming language, released by Apple in 2014, the language is flexible, scalable and can easily adapt the programming model to add modern functionality to any application.

If you are looking for a high-level language with modern features and tools, Swift is the best option. It is primarily used to develop apps for their iOS and macOS operating systems, but can also be used for other platforms, including Android and Linux.

There are many reasons why Swift is a good choice for developers who want to build apps for mobile devices. First, it’s fast – it uses a lightweight syntax that makes it easy to write code quickly and run efficiently on devices. It also has a high level of security in its design, which can help reduce bugs in your app and ensure that it runs smoothly without crashing or freezing when you use it on the go . Finally, the language itself has support from Apple: the company provides documentation on how to use Swift with its products, as well as regular updates on new features planned for future versions of iOS (meaning that there will always be something new!)

Applications developed in Swift include Lyft, LinkedIn and many others.


Flutter is a free and open source mobile application development framework created by Google. It is used to develop applications for Android and iOS written in Dart, a programming language developed by Google. With Flutter, you can quickly and easily create beautiful native apps.

Flutter uses its own rendering engine, which makes it easy to work with widgets and make changes without affecting the rest of your app. So developing in Flutter feels like working with HTML or CSS instead of the low-level native platform API.

Another advantage of using Flutter is that it allows you to reuse code across platforms. (iOS/Android)So if you have an existing codebase for any platform, you can use that instead of writing new boilerplate code every time.

Objective C

Objective-C is a superset of C in that it combines object-oriented capabilities and a dynamic runtime.

It was created by Brad Cox and Tom Love at the Stepstone Research Center (and later by Adele Goldberg) in 1986, originally for NeXTStep, the operating system for the first NeXT computer.

When Steve Jobs returned to Apple, he oversaw the use of Objective-C for all Mac applications on the Macintosh software team. In 2003, Apple Inc. NeXT was acquired by NeXT, marking the transition from Objective-C, used only on NeXT computers, to Objective-C, used by both companies’ products, including iOS (iPhone) mobile phones/tablets. goes.

Hybrid Apps

Hybrid apps are “cross-platform” that don’t need to be built separately for Android and iOS. So you can build a single app and deploy it on both platforms, doubling your reach and halving your development work.



React Native was born as a project during an internal hackathon at Facebook, and it turned out so well that it has become one of the most popular coding languages, and so who can create applications that run on any platform? work.
React Native allows developers to write sections of code and reuse them across different platforms. After implementing the code, they can easily adapt it for other platforms, styling elements and fine-tuning detail.
In addition to code reuse, the open-source library in React Native also contains a number of pre-built components. This means that you can easily use components already developed by others, which allows for great speed of development.
Another major advantage of React Native is the support for third-party plugins. So if your e-commerce application requires a calendar, you don’t need to create a calendar from the beginning. React Native allows you to find a pre-built calendar available for use (there are a lot of them) and simply integrate it into your application.

Uber and Airbnb are coded in this language, with hybrid programming languages ​​in mind!



Cordova allows you to code up a hybrid application, then ported to different operating systems. Cordova is not a language but a mobile development framework.
You don’t need to master native iOS or Android languages ​​because Cordova works with web languages: HTML5, CSS3, and JavaScript.

Walmart and Adobe use Cordova.
