Watches and a scale for Health Connect
OpenWatch
OpenWatch pairs your watch and your scale over Bluetooth, copies what they record into Health Connect, and manages them. No account, no server, no internet permission.
The devices it works with
Wear OS watches
The OpenWatch watch app records heart rate, steps and floors and syncs them on a tap or a schedule, with an estimated sleep session and resting heart rate each night.
Xiaomi S400 scale
Every weigh-in saved to Health Connect as it happens, with the app open or closed. Body fat, lean mass and body water are estimated on the phone.
Where your data goes
