Create cross-platform mobile applications with Kotlin
In addition to being the official language for Android development, Kotlin is a proven technology for building cross-platform mobile applications. It eliminates all the disadvantages of other leading cross-platform approaches and lets you create mobile apps with native performance and UIs while keeping the business logic fully shared.
Native UI
The Android and iOS versions of an application often have a lot in common, but they can also differ significantly, especially in terms of their UIs. KMM does not put any limitations on how you develop the app's UI. You are free to use whatever style and frameworks you want, including the most modern ones, such as Jetpack Compose for Android or SwiftUI for iOS. With KMM you will be able to use any platform-specific UI elements, such as scrolls or navigation, and provide your users with a native UI experience.
Native Performance
KMM is seamlessly integrated with your mobile project so you can ensure it is both fast and responsive. To provide full native performance, shared code is compiled to JVM bytecode with Kotlin/JVM and to native binaries with Kotlin/Native.
Use iOS and Android features without any overhead
Kotlin Multiplatform Mobile does not impose any restrictions on how you work with the platforms. Whenever a task cannot be solved in the shared code, or whenever you want to use specific native features, you can use the expect/actual pattern to seamlessly write platform-specific code.
Who uses Kotlin Multiplatform Mobile
Sharing Kotlin code between mobile platforms has already saved a lot of time and effort for many companies.
