A local restaurant chain wanted to create an app for online ordering. The marketing team knew they needed to reach both iOS and Android users. When they talked to developers, the first question was: “Which programming language for mobile app development should we use?”
This choice would affect the app’s cost, how quickly they could launch, and how well it would work for their customers. Many businesses face this same challenge when developing mobile apps. Picking the wrong programming language for app is like building your store in the wrong location – it can cost you time, money, and customers.
At iZoticus, we understand that selecting the right programming languages for app development is important for meeting your business goals. So, here, we’ve compiled a list of the five best programming language for mobile app development in 2025.
iOS Development
Apple came up with Swift in 2014 to replace Objective-C. If you ask us, “What programming language are iOS apps written in?” Swift is our first answer. It’s now the main way to build iPhone and iPad apps.
Swift
Apple introduced Swift in 2014 to replace their older programming language for mobile app development. It’s now the main way to build iPhone and iPad apps.
Advantages:
- Safer and more concise code with fewer errors
- Faster development and runtime performance
- Excellent memory management
- Gets regular updates from Apple
Best for: Making apps that only run on iPhones and iPads and need to use all of Apple’s features.
Objective-C
This is an older language for maintaining legacy iOS applications and working with older codebases. This is an older programming language of iPhone development that’s still used to fix and update older codebases.
Advantages:
- Mature programming language for mobile app development with extensive libraries
- Compatible with C and C++ code
- Still supported by Apple
Best for: Maintaining and updating apps that were built years ago with Objective-C.

Android Development
Android is a Google-run open-source software development platform. Though Google has mobile device options, such as phones and tablets, other manufacturers, including Samsung, Huawei, Microsoft, and more, also make phones and tablets powered by the Android OS.
Kotlin
If you ask us about the best Android programming language, Kotlin is often our recommendation. Google officially endorsed Kotlin in 2017 for making Android apps.
The Android application programming language ecosystem has changed significantly, with Kotlin becoming the preferred choice for new development.

- More concise than Java, requiring less boilerplate code
- Fewer app crashes
- Full compatibility with existing Java code
- Excellent tool support with Android Studio
Best for: Making new Android apps that need clean architecture and robust performance.
Java
For years, when someone asked, “What programming language are android apps written in?” the standard answer was Java. As programming languages for Android continue to evolve, Java maintains its relevance alongside newer options. Many developers still use this because they know it too well.
Advantages:
- Massive community and resource availability
- Platform independence
- Strong typing and robust error-checking
- Extensive libraries and documentation
Best for: Android projects with teams already experienced in this Android app programming language, or those requiring specific Java libraries.

Cross-Platform Development
Cross-platform development lets businesses build apps that work on both Android and iOS using a single codebase, saving time and reducing costs.
React Native
The ideal programming language for mobile app development isn’t always platform-specific. React Native, developed by Facebook, lets developers write code once and use it for both iPhone and Android phones, making it an efficient choice for many development teams and businesses.
Advantages:
- Approximately 70-90% code reuse between platforms
- Access to native components when needed
- Live reloading for quicker iteration
- Large community and extensive third-party libraries
Best for: Projects targeting both iOS and Android with budget or time constraints.
Flutter
Flutter has received huge attention from businesses when choosing programming languages for application development. Google’s Flutter framework uses Dart to create apps for mobile, web, and desktop from a single codebase. It’s one of the latest development languages that businesses must consider for their next development project.
Advantages:
- Consistent UI and behavior across platforms
- Hot reload functionality for rapid development
- Custom, highly customizable widgets
- Growing community and Google support

Advantages:
- Use existing web development skills
- Single codebase for multiple platforms
- Access to device features through plugins
- Faster development for simpler applications
Best for: Projects with tight budgets or when you want both a web and mobile presence with shared code.
Note: Cordova is declining in popularity, while Capacitor is rising as a modern alternative.
