Connection help and supported devices

Wear or activate the device and enable heart-rate broadcast mode when it has one.
Close the wearable companion app because many devices accept only one live connection.
Tap Connect wearable and wait for the first heart-rate value.

The mobile app is recommended. Chrome or Edge can provide active-tab recording as a web backup.

Compatible live heart-rate streams are detected automatically.
Enable heart-rate broadcast mode when your wearable provides it.
Wearables that restrict live data to a companion app require a dedicated integration.
Bluetooth pairing alone does not guarantee that a device shares live heart rate.
