Jetpack Compose is the modern Android toolkit for building native UI with intuitive Kotlin APIs. Compose simplifies and accelerates UI development, including adaptive design for all form factors—from phones, tablets, and foldables to TVs and wearables.

Compose provides pre-built UI components so you can implement your app's UI with graphics, animations, and other visual elements with minimal code.
