Taking mobile app development into consideration, we will have a dozen questions in mind. The questions that always stand ahead in the queue here will be regarding the programming languages for mobile app development. Let the reason be to choose the best programming language for the best results, or be it a reason to learn an additional programming language to take your next step in your programming career. However, choosing a language to learn is a big step you make. Each language will have its pros and cons and the requirements for each language will vary. Here is a list of 5 programming languages we think to be the best.


Java developed by James Gosling in Sun Microsystem, and now owned by Oracle can be contemplated as a complete programming language. Introduced after C and C++, Java today is the best programming language for Android app programming. A quick and error-free mobile app development is feasible with Java. and due to its flexibility, it is preferred by the majority of organizations. When there are more than 7 million Java programmers in the world, anyone can now develop anything with Java. any challenges you may face will be handled well by its huge community. With the utilization of JVM, Java runs smoothly on any device. With all the characteristics and best features, Java is one of the most established Android app development programming languages, that you may choose to develop an app or learn.


Developed in 2011 by JetBrains, Kotlin is a statically typed programming language. In 10 years, Kotlin has expanded exponentially and as a result, the popularity it achieved was great. The interoperability, running on JVM, and its versatility in both front-end and back-end development are a few of the reasons that resulted in its popularity. Kotlin can somewhat replace Java in developing Android apps- because it develops apps with functionalities that were not practicable with Java. Even though Kotlin is in the early stages, it is expected to have a speedy growth and at some point, developers anticipate that it will completely replace Java in Android app development.

Objective C

The object-oriented general-purpose programming language, developed by Tom Love and Brad Cox in 1984, is Objective C. Before the advent of Swift, it was Objective C used to develop iOS apps. The best part of Objective C is while programming the developer can use both C and C++, whereas in Swift this was not possible. The best you can accomplish with Objective C is dynamic typing and message passing. With the popularity and usefulness today Swift has replaced Objective C to an extent. Still, the queries on StackOverflow and C projects on GitHub prove that it will be worth enough if you prefer to learn or develop an app with Objective C.


Swift has achieved immense popularity, since its introduction by Apple in the year 2014. If you plan to develop an app that is high-performance and interactive for both iOS and macOS then Swift will be the best choice you can make. Similar to Kotlin, Swift is very young. Still, within this short period, Swift has proved that it will be one of the promising languages to develop iOS apps. From the developer’s point of view, Swift can help you write code both cleaner and shorter compared to that of Objective C. Besides, Swift has an amazing memory management system. This allows the programmers to focus on the programming logic rather than thinking too seriously about where to allocate memory for each object. This in turn will make the programming task an effortless one. If you wish to develop an app for iOS, tvOS, WatchOS, or macOS, then Swift is your choice. Since 2015, it is an open-source programming language and so now anyone can make their contribution.


Developed by Bjarne Stroustrup in 1985, C++ is an object-oriented programming language. Also, it is a cross-platform programming language, where you can experience features like low-level memory manipulation. Some examples of the tools developed using C++ include Photoshop, World of Warcraft, Google chrome, and PayPal. This indicates that C++ is one of the strongest and most powerful languages for mobile app development. The consolidating debugging experience and powerful environment of C++ can be used to build cross-platform mobile apps for platforms like Android, Windows, and iOS. For high-performance mobile apps and games working on multiple platforms, one can for sure depend on C++.


Before you choose to learn any of the above programming languages, let me say that you have to ask 3 questions to yourself.

  1. Which platform do you wish to develop an app on?

  2. What is your previous coding experience?

  3. How much time have you got to learn?

The language you choose to learn will depend on the answers to these questions. In the ever-evolving scenario of mobile app development, each day a new programming language is introduced to the public. The aim is to overcome the challenges of the current programming language and desire to replace it one day. So when we have so many to choose from, it is important to make the right choice. However, with your requirements being clean and precise choosing your language is not a big task. For iOS learn Swift, for Android Kotlin, and for Hybrid choose the best cross-platform language you find.
