“One exciting trend for Duolingo is that the more that we use Kotlin Multiplatform internally, the more we find ourselves speeding up in terms of shipping. It turns out after you learn something, you get really good at it. […] Now there's a lot more confidence behind it and we're building up that knowledge.”

Sony's journey to Kotlin Multiplatform wasn't just about efficiency; it was about capability.
We migrated from native plans to a unified KMP and Compose Multiplatform workflow, delivering a robust companion app for our flagship headphones, with background execution and sensor integration to millions of users worldwide.

TechLead at Sony
“Adopting KMP for our experimentation library was a calculated bet. Best case: we save time and guarantee cross-platform consistency. Worst case: we rewrite the library in Swift. The reality exceeded our expectations: KMP performed great on iOS, proving it’s a viable, long-term solution for our team.”
Diego Gómez Olvera
Principal Android Developer
“After a successful initial test with the payments feature, we expanded Kotlin Multiplatform to our entire McDonald's application. With KMP, we saw fewer crashes and better performance across both platforms after the launch.
We transitioned from a separate Android and iOS team to a more unified mobile team.”

Project Manager, McDonald’s app at Umain
By sharing over 80% of logic across iOS and Android, Forbes now rolls out new features simultaneously on both platforms, keeping the flexibility to customize features based on the specific platform. This allows the team to innovate and respond to market needs faster.
“We consider Kotlin Multiplatform validated in our Google Docs experiment […] we consider the experiment a success […] We’re actually very happy with it”

BiliBili (China version) has adopted Kotlin Multiplatform and Compose Multiplatform for the Instant Message feature.
Kotlin Multiplatform is a technology that allows you to create applications for various platforms and efficiently reuse code across them while retaining the benefits of native programming. Your applications will run on iOS, Android, macOS, Windows, Linux, and more.
Kotlin Multiplatform is the core technology that lets you share code – such as business logic, data models, networking, and more – across multiple platforms, including Android, iOS, desktop, web, and server. It focuses on code reuse without replacing the native UI unless you want it to.
Compose Multiplatform
is an optional UI framework built on top of Kotlin Multiplatform. It allows you to share your user interface across platforms using a modern, declarative approach similar to Jetpack Compose on Android. You can use it to build visually appealing, responsive UIs for Android, iOS, desktop, and web from a single codebase.
Yes, Kotlin Multiplatform is production-ready for all supported platforms – Android, iOS, desktop, web, and server. Compose Multiplatform is stable for Android, iOS, and desktop, while the web target is currently in Beta.

No. You can start small by sharing a module or feature and integrating it into your existing app. KMP is designed for gradual adoption, making it easy to incrementally introduce cross-platform code.
