Today at Google I/O, we announced the most significant Android Wear update since its launch two years ago: Android Wear 2.0. Based on what we’ve learned from users and developers, we're evolving the platform to improve key experiences on the watch, including watch faces, messaging, and fitness.
Android Wear 2.0 will be available to users this fall. We’re making a Developer Preview available today and plan to release additional updates throughout the summer, so please send us your feedback early and often. Also, please keep in mind that this preview is a work in progress, and is not yet intended for daily use.
