Our developers say
The best thing about Kotlin is its concise syntax that lets you write less code, so I can do tasks faster. It has modern features like null safety that make it a reliable and efficient language, and its codebase is easy to maintain. I also like how it seamlessly integrates with the Java ecosystem, so we can use it in Java-based projects. While Google prefers Kotlin for building native Android apps, you can use it for iOS or web development too, and this cross-platform support helps us do projects faster and cut costs.

FAQs
Why choose Kotlin programming language for your app development project?
There are several reasons why you should opt for Kotlin when building applications.
- Google recommends Kotlin for Android app development.
- Kotlin is a concise programming language with enhanced readability. Using it reduces common code errors and the amount of code developers need to write, which contributes to faster app development.
- Being fully interoperable with Java code, Kotlin code can be easily integrated into existing Java-based apps.
- You can use the Kotlin Multiplatform technology to build cross-platform applications that share code between Android, iOS, web, and desktop platforms.
- Unlike Java, Kotlin has features that help write code with fewer errors and reduce the likelihood of app crashes.
- Kotlin’s coroutines feature streamlines complex background operations in the app, resulting in faster and smoother performance.
What well-known applications are built with Kotlin?
Many cutting-edge mobile applications are built using Kotlin, with the most common case studies including Netflix, Pinterest, Coursera, Airbnb, Evernote, Square, Trello, and Uber.
When to choose Kotlin Multiplatform for cross-platform app development?
Development companies can use Kotlin Multiplatform to build applications that share business logic across multiple platforms but have platform-specific UI components. This means that developers can write a single codebase to develop platform-independent core functionality and have to create only separate frontends for Android, iOS, web, and desktop.
Kotlin Multiplatform is also a cost-effective option for companies that already have an Android or iOS app and want to reuse the existing business logic for other platforms.
