## At a glance

- **Maintainer**: JetBrains (Google-endorsed for Android)
- **First release**: 2011
- **Language**: Kotlin
- **License**: Apache 2.0

## Learning curve

Easy coming from Java and pleasant from scratch; coroutines and Jetpack Compose idioms take a little longer to master.

## Performance

Full native Android performance with direct access to every platform API; also a strong JVM backend language (Ktor, Spring).

## Ecosystem

Android-first tooling with Jetpack Compose as the modern UI kit, plus Kotlin Multiplatform for sharing logic with iOS.

## Ideal for

- Native Android apps of any size
- Sharing business logic across platforms with Kotlin Multiplatform
- Teams covering Android plus JVM backend with one language
- Apps needing deep Android integration (background work, sensors)

## Pros

- Google's preferred language for Android development
- Concise syntax and null safety eliminate common Java bugs
- Jetpack Compose provides a modern declarative UI toolkit
- 100% interoperable with existing Java code
- Kotlin Multiplatform shares logic with iOS without giving up native UI

## Cons

- Android-centric. IOS needs Swift or extra Kotlin Multiplatform work
- Gradle build times frustrate large projects
- Multiplatform UI story is less mature than Flutter's
