Full-screen [tiles](https://developer.android.com/training/wearables/tiles) have been a go-to surface on Wear OS, providing users
with instant, glanceable access to their essential updates. As the Android
ecosystem moves toward a unified vision for [widgets](https://developer.android.com/develop/ui/compose/glance), we're bringing the
watch closer to the rest of the Android family with the goal of minimizing
efforts for developers. The next step in the evolution of tiles are the flexible
and dynamic Wear Widgets.

[Jetpack Glance](https://developer.android.com/jetpack/androidx/releases/glance-wear) and the [Remote Compose](https://developer.android.com/jetpack/androidx/releases/compose-remote) framework power Wear widgets,
offering greater expressiveness and consistency with Compose than the Tiles
ProtoLayout libraries. Wear widgets support two card types---small
and
large---that align perfectly with the 2x1 and 2x2 formats on mobile, ensuring your
designs feel cohesive across devices, while still allowing you to [optimize your
designs for the wrist](https://developer.android.com/design/ui/wear/guides/get-started/design-for-wearables/principles#optimize-for-wrist). You can adapt the UI from the [`mainSlot`](https://developer.android.com/training/wearables/tiles/get_started?version=3#slots) of your
full-screen tile to a 2x2 widget.

If your application already has an existing tile and you want to learn how to
transition users to the new widget format, read the [Migrate from tiles to
widgets](https://developer.android.com/training/wearables/widgets/migration) guide.
