Sleep Cycle does not support all Android watches. Our integration requires Wear OS 2, and works with any modern Wear OS watch from many different developers
(check here for reference - https://wearos.google.com/#find-your-watch).
Android watches track things differently from the Apple Watch. The Android one works more as a remote, used to begin tracking on the phone. It doesn’t track your actual sleep on its own, including its automatic tracking. The Android watch doesn’t record sounds, since it’s mainly a remote to start tracking your sleep from your phone.
