What Is The Best Language For Mobile App Development?

The question “What is the best language for mobile app development?” has no one-size-fits-all answer. In this article, we will explore different programming languages and help you choose the most appropriate tech stack for your app wisely.

Native App Development Languages

Native app development involves building applications specifically for a particular operating system, such as iOS or Android.

Swift (iOS)

Swift is Apple's latest programming language for iOS app development. Known for its clean syntax, high performance, and safety features, Swift offers numerous libraries and frameworks. Ultimately, this is why developers choose it to build feature-rich iOS applications.

Java/Kotlin (Android)

Java has long been the official language for Android app development and remains widely used. Kotlin, a more modern language - has rapidly gained popularity thanks to its compatibility with Java, enhanced readability, and reduced boilerplate code.

Cross-Platform App Development Languages

A zest for cross-platform development lies in the possibility of killing two birds with one stone: it allows building apps that run on different systems using a single codebase. Thanks to this, stakeholders save time and costs.


As the most widely used programming language for web development, JavaScript has also gained prominence as a cross-platform app development language. The advent of frameworks like React Native and Apache Cordova (PhoneGap) eventually allowed engineers to build cross-platform mobile apps using JavaScript.


Developed by Google, Dart is a language designed explicitly for building cross-platform mobile applications using the Flutter framework. Dart's Just-In-Time (JIT) and Ahead-of-Time (AOT) compilation options offer efficient performance and fast development cycles. Flutter's expressive UI components and hot-reload feature allow developers to create visually rich and responsive user interfaces.


Owned by Microsoft, C# is a versatile language. One of its many capabilities is cross-platform app development with Xamarin. Xamarin lets developers create native mobile applications for iOS, Android, and Windows platforms using a shared C# codebase. C#'s integration with the .NET ecosystem provides access to a wide range of libraries and APIs, facilitating robust and feature-rich app development across platforms.

Web-Based App Development Languages

Web-based apps offer compatibility across different devices and operating systems as they run in a browser.


These three technologies work together: HTML5 provides the structure, CSS adds style and presentation, and JavaScript enables interactivity and functionality. The final applications are accessible through URLs and do not require installation from an app store.


TypeScript enhances JavaScript by adding static typing and advanced features to support scalable and maintainable web applications. This language enables catching errors during development through static type checking, improving code quality. Its modern features, such as classes, interfaces, and modules, facilitate code organization and promote code reusability.


With a myriad of frameworks and libraries, such as Django, Flask, and Pyramid, Python stands out as a robust ecosystem with clean syntax and an extensive standard library. Python’s object-oriented paradigm, combined with its ability to integrate with other languages, enables complex web applications’ seamless development.


PHP is a server-side scripting language designed for web-based app development, well-suited for creating dynamic and interactive websites. With its simplicity and ability to embed code within HTML, PHP enables developers to seamlessly mix logic and presentation, making it easy to generate dynamic content and handle data processing on the server side.


Ruby is a dynamic and expressive programming language renowned for its simplicity and developer-friendly syntax. Ruby on Rails, a powerful web framework built on top of Ruby, accelerates the development process thanks to its focus on convention over configuration. It also streamlines the creation of database-backed web applications.

Factors to Consider When Choosing a Development Language

First and foremost, consider the complexity of your app's features and functionalities. For more sophisticated apps, native development might be the better option, as it allows for seamless integration with the platform's capabilities.

Secondly, study your target audience's preferences and behaviour. If it primarily uses a specific platform, opt for a native app.

Thirdly, consider time-to-market. Cross-platform languages, allowing code sharing across platforms, can significantly reduce development time.

Finally, think about budget constraints, a critical factor for many businesses in terms of mobile app development services. Native app development may require more resources than cross-platform or web-based alternatives.

Case Studies and Real-Life Examples

Let’s review several popular mobile apps and see how they were built. 


Instagram initially started as an iOS-exclusive app developed using Objective-C. Later, they expanded to Android using Java for native development.

The native approach for both iOS and Android allowed Instagram to tailor the user experience to each platform's nuances. The app's smooth performance, intuitive interface, and quick updates contributed to its widespread adoption.


Walmart, the world's largest retail corporation, opted for cross-platform app development using the Flutter framework and Dart programming language. Flutter's expressive UI components and hot-reload feature allowed Walmart's development team to experiment with different design elements and iterate quickly.

The resulting app is highly responsive and visually engaging. Its fluid animations, swift loading, and efficient search and checkout processes contributed to increased customer retention and loyalty.


The dating app was initially designed as a native app for both iOS and Android devices. This approach allowed Tinder to provide a smooth and intuitive user experience to its vast user base. Prioritising platform-specific development allowed Tinder to reach an impeccably working swipe-based interface, real-time messaging, and location-based matching mechanisms.


The electric vehicle manufacturer chose native app development for iOS and Android platforms (Swift for iOS, Java/Kotlin for Android) to leverage platform-specific features and seamlessly integrate their cars and mobile app. 

As a result, Tesla's app offers exceptional performance and real-time updates for car owners, demonstrating the brand’s commitment to innovation. For instance, drivers can control their vehicles remotely, monitor charging status, and receive notifications about their car's health.

What Is The Best Language For Mobile App Development?

An optimal programming language choice depends on various factors discussed above. Creating a high-performance app with access to platform-specific features requires native app development. On the other hand, if you need to target multiple platforms quickly, efficiently, and cost-effectively, cross-platform or web-based app development is an ideal choice.

Whichever tech stack you choose, collaborating with a reputable software development company in the UK and Switzerland like S-PRO can make a significant difference in the success of your mobile app. We will conduct an initial advisory, assessing your project requirements and goals to pick the best possible mobile development language.


The answer to the question "What is the best language for mobile app development?" depends on the particular project. It is essential to carefully assess your app's requirements, target audience, budget constraints, and development team's expertise before deciding. Completing this list will reveal each development approach's advantages and drawbacks regarding the project in question.
