Breakthroughs and innovation are two of the key drivers of technological progress, transforming the whole development industry into one of the most dynamic economic sectors. In particular, the mobile apps sector has grown several times over a surprisingly short time. There are more than 1,000 programming languages in the world and every year their number is increasing. New promising languages appear, and some become outdated and no longer in demand. What languages are considered the most relevant today? Which languages should you study so as not to waste your time? 

Top App Developing Languages in 2021

Today, any company that either sells products or assists customers in achieving any goals has already created or is considering the possibility of building an application for their customers. Of course, businessmen should carefully study the functionality of the future product and the necessary resources that will be connected to it, but remember that the technology you work with should be selected based on your specific needs. In this regard, it is better to approach the appkong.com professionals.

Development languages ​​are tools that specialists apply to render, create, and deploy different varieties of mobile software. They also ​​vary greatly in their development possibilities, functionality, and the available tools they offer. That’s the reason why several languages fit more to certain development tasks. The best backend providers around the globe support in-demand languages ​​for creating browser and mobile software. And you must understand that knowing their possibilities will facilitate the selection of the most appropriate option for a specific project.

Whether you wish to build your app from scratch, there are a number of developing languages available. The ones listed below are ideal for building an entire application from scratch while offering multi-platform capabilities.

1. Java

Since its emergence, Java is known to be the key basis for mobile apps deployment on Android. It also provides cross-platform support. Moreover, Java apps can be easily integrated into various OS. Java software works on the Write Once Run Anywhere (WORA) principle — it operates without failures on any Java-compatible gadget without the need to rewrite the code. Although Java is a relatively old development language, it keeps its popularity today. According to the PYPL ranking, Java is the most preferred programming option among employers.

Spheres of application: along with business apps, it is widely used in the Android mobile operating system.

2. Kotlin

This is the newest development language fully compatible with Java. These siblings are also interchangeable. Last year, Google named Kotlin “the primary language for developing Android applications.” Among the advantages over Java, it is worth noting the scalability of Kotlin. There is no doubt that it deserves the title of a starting programming tool for newbies, which is also enhanced by the fact that one is free to use Android Studio with it. Nevertheless, in combination with Unity, it is a preferred choice for newbies.

Spheres of usage: most often for the creation of Android apps.

3. C/C++

Microsoft designed C # as a faster and more secure “C” variant. It is fully integrated with the Microsoft.NET software framework, which supports the development of Windows apps, browser modules, and mobile devices. C# offers common codebases, a large code library, and various data types. C++ is the best solution for tasks where maximum performance and flexibility are important – writing compilers, drivers, low-level utilities, and libraries for operating systems, etc.

Spheres of usage: deployment of applications for Windows, mobile apps, games.

4. Swift

Swift is an incredibly powerful and simple programming language introduced by Apple in 2014 that opens the way for many programmers to create apps for iOS, macOS, Apple TV, and Apple Watch. This language inherited ideas from Objective-C, Rust, Haskell, C #, and others. It uses secure coding patterns and new features to make coding fun and interesting. Created by Chris Lattner, it’s robust, fast, and open-minded, making it even easier to create apps for the world’s most popular phone.

Spheres of application: development of applications for iOS, macOS, watchOS, and tvOS.

5. Rust

Rust is a young language that is constantly changing, evolving, trying to solve the well-known shortcomings of not only C ++ but other languages as well. It has everything you need to develop web applications. Its functionality is suitable for both frontend and backend. Rust will become an increasingly popular language, and it is quite possible that with proper development and refinement, it will be able to bypass today’s main competitors.

Spheres of application: development of native and web applications.

Top IEEE Mobile Development Languages

The IEEE ranking includes 55 out of 300+ languages ​​used on GitHub. The sample was ranked according to the frequency with which a particular language is found on eight different platforms and sites, such as Google Trends and Reddit. Also, languages ​​are associated with tags that indicate the scope of their application.

Java, C, and C ++ remain the leaders in mobile development. Google continues to push Kotlin as a key Android development language, although it is unlikely to overtake Java anytime soon. Instead of Objective-C, until recently the dominant iOS development language, Apple is actively promoting Swift. The support of the companies that created these ecosystems places the two younger languages ​​high on the list. So, the list of the most widely used development languages looks like this:

1. Java;
2. Swift;
3. Kotlin;
4. Dart;
5. Objective-C;
6. Scala;
7. Delphi.

Although the ratings change every year, some languages improve and become more demanded, while others get outdated and fall below the top-10. Some of them are found in the first positions from year to year. This means that they are more versatile and popular than the rest.

And yet, when choosing a programming language for your app, you should not rely only on its popularity. Considering any option requires mindfulness and a clear goal. So, before you choose a certain developer, think about the functionality and purpose of your app, and only then start your work! Good luck!
