Right programming language for mobile app development is the backbone of any app. Without proper language, the development process would become longer and costlier too. When you select the appropriate mobile app development language, it not only increases the speed of development but also saves lots of effort in writing complex codes. The entire process becomes less complex and more reusable. To ease your selection process, we’ve listed below the best programming languages for mobile apps development in 2025 that will enable you to make an informed decision.
List of Top Programming Languages for Mobile App Development
Table of Contents
1. Kotlin: Programming Language for Android App Development
JetBrains introduced the language Kotlin but it became popular only after it was officially adopted by Google in 2017. Kotlin is one of the best app programming languages because of its simple and concise syntax. As the codes of this language are less complex that reduces the chances of errors and also makes the development process faster. Although Java is one of the favourite programming languages Kotlin addresses numerous flaws present in Java such as null pointer expectations. This adds to the null safety features in the language directly.
2. Java: Popular Programming Language for Android App
These days Kotlin has gained popularity for Android app development yet Java remains the most widely used Android app development language. It is such a language that allows the code to run on any device that has JVM. Because of its vast ecosystem of libraries and frameworks, the development of apps has become efficient. Besides that, it allows you to gain the support and guidance of a large and active community. The robust performance of Java makes it perfect for developing complex Android applications.
3. Swift: Perfect for iOS App Development
Usually, Objective-C is used as the go-to language for iOS app development but the modern features present in Swift have won a vital place for developers. Since its launch, it has been popular for its ease of use, speed and safety. Most importantly it blends perfectly with Apple’s ecosystem and hence has been the perfect iOS development language. This is considered more efficient than Objective-C and also has a strong typing system. The error-handling mechanism of Swift is also strong which reduces common programming errors.
4. Objective-C: A Commonly Used iOS App Development Language
Although Swift is today quite popular as an iOS app development language Objective-C still remains relevant. Because of its foundation in C, it is still being used for developing iOS apps. This programming language has the capability to blend with object-oriented concepts and offer granular control of the process of development. Over the years lots of libraries and documentation have been introduced in it which has offered it a rich and mature ecosystem. Besides that, its root in C and its object-oriented nature make it better compatible.
5. Flutter: Dart-Based Programming Language
Flutter is one of the best languages for mobile app development. Basically, this language has been developed by Google. That’s where it gained all its popularity from. With expressive UI components, it is known for its fast performance. Many developers prefer this programming language for developing apps because of its faster speed. With the use of this dart-based language, developers are able to build visually stunning apps that too by using a single codebase. Moreover, it ensures consistency across different platforms be it Android or iOS.
6. React Native: Java-Script-based Programming Language
React Native is backed by Facebook and is considered one of the best programming languages for mobile app development. As it is a Java Script-based programming language it leverages Javascript and React to build mobile apps. It is one of the most favourite programming languages for app development because of its reusable components. A large developer community relies on this language for cross-platform development of apps. The mobile apps developed with React Native are consistent across both Android and iOS systems.
7. Xamarin: C# Based Programming Language
One of the best programming languages for app development is Xamarin. This is the language that smoothly integrates with Microsoft’s ecosystem. Due to this, it is considered a developer’s favourite choice, especially for those who are familiar with C#. It can be used as both iOS and Android app development language as it offers native performance and at the same time allows to share code across different platforms with ease.
8. Rust: Potential Programming Language
Commonly known for its memory safety, Rust is considered one of the best languages for application development. Unlike many other programming languages, it has high performance. Usually, developers prefer to explore it for system-level programming and at times for performance-critical applications. That makes it one of the potential programming languages for mobile development.
9. Jetpack Compose: Kotlin Based Programming Language
This mobile app development language is a modern UI toolkit that comes from Google. This has simplified and eased the development of Android apps. It has a declarative UI design using which developers can easily build responsive layouts. For this, they need to use less boilerplate codes which ultimately streamline the entire development process.
10. Python: The most Famous App Development language
Most of the developers consider Python as one of the best programming languages for app development. With the use of Kivy and Beeware libraries, this is implemented. Kivy is an open source library that helps in building cross-platform applications for both iOS and Android systems. On the other hand, BeeWare is a suite of UI tools that helps in creative native Android apps. Nowadays Python is relatively rarely used however there are still many developers who prefer it over other languages.
Conclusion
In the world of mobile app development, the best programming language plays a crucial role. Over time the old programming languages are getting updated and new ones are taking their place. From Kotlin to React native each language offers compelling solutions.
Well, it is important for the developers to understand the uses of each specific language and pick the one that is appropriate for their app development.
