Wear OS 6 introduces several features to help enhance your Wear OS app
experience. Before you add these features to your app, [prepare your app](https://developer.android.com/training/wearables/versions/6/changes) for
compatibility with Wear OS 6.

## Support for Material 3 Expressive

Wear OS 6 includes a design refresh that's based on Material 3 Expressive,
which is available in the latest release of the [Compose for Wear OS](https://developer.android.com/jetpack/androidx/releases/wear-compose)
and [Wear OS ProtoLayout](https://developer.android.com/jetpack/androidx/releases/wear-protolayout) libraries in Jetpack.

Material 3 Expressive, supported on Wear OS 3 and higher, helps you transform
the expressiveness and creativity of your app's layouts and tiles, making the
most of the round form factor. Explore different shape and typography
combinations, including the latest system font support, and experiment with
dynamic color theming.

Material 3 Expressive also offers the following layout improvements:

- An edge-hugging button shape that invites users to take action or learn more.
- Expressive motion and more prominent scroll indicators within collections such as lists, offering more fluidity and control when selecting from a series of options.
- A multi-slot tile layout, supporting up to three columns, that creates consistency while offering customizable expressiveness of key information.
