Quizlet migrated their business logic from a shared JavaScript approach to KMM and drastically improved the performance of both their Android and iOS applications.Sharing Kotlin code between mobile platforms has already saved a lot of time and effort for many companies. Shared code, written in Kotlin, is compiled to JVM bytecode with Kotlin/JVM and to native binaries with Kotlin/Native, so you can use your KMM business-logic modules just like any other regular mobile library. KMM is seamlessly integrated with your mobile project. Use a single codebase for the business logic of iOS and Android apps and write platform-specific code only where it’s necessary, to implement a native UI or when working with platform-specific APIs.

With KMM, you can get this flexibility and retain the benefits of native programming. That’s why it’s natural to share some parts of an application across platforms while keeping other parts completely separate.

At the same time, the application’s business logic, including such features as data management, analytics, and authentication, is often identical. 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 UI – from subtle variations in scrolling behavior to completely divergent navigation logic. It uses the multiplatform capabilities of Kotlin and includes various tools and features designed to make the end-to-end experience of building mobile cross-platform applications as enjoyable and efficient as possible. Kotlin Multiplatform Mobile ( KMM) is an SDK for cross-platform mobile development provided by JetBrains. Reusing code between mobile platforms has never been so easy!

Join such great teams as VMWare, Autodesk, and Yandex who are sharing code in their mobile apps using Kotlin. It includes the new KMM Plugin for Android Studio, which allows you to write, run, test, and debug shared code in the same IDE. Today KMM goes Alpha, and you can start sharing business logic in your mobile apps with it right away. Kotlin Multiplatform Mobile (KMM) is an SDK that allows you to use the same business logic code in both iOS and Android applications.
