Watch HRM BLE

Turn your Apple Watch into a Bluetooth heart rate monitor for your bike computer or indoor training app. Send live BPM directly from your wrist, with no iPhone relay or extra chest strap. On your Watch • Live heart rate and receiver connection status. • Background colors that show your current heart rate zone. • Zones based on maximum heart rate, an age estimate, heart rate reserve or your own BPM thresholds. • Number wheels and customizable colors for each zone. • An optional Smart Stack widget showing the latest heart rate snapshot and its age. Get started 1. Open Watch HRM BLE on your Watch, tap Start and allow the requested Health and Bluetooth access. 2. On a compatible bike computer or training app, search for a Bluetooth heart rate sensor and select Watch HRM BLE. 3. Check that the receiver shows changing BPM. When you finish, open Controls on the Watch and choose End broadcast and confirm. Compatibility Requires Apple Watch with watchOS 26 or later and a receiver that supports Bluetooth Low Energy (BLE) heart rate monitors. Compatibility depends on the receiver model and software; see the support page for tested devices and apps. ANT+-only receivers are not supported. Free, with no account or ads. Uses Apple Health and a workout session to read heart rate. The app discards its workout record when you end the broadcast; sessions can still affect Activity rings. Use a receiver you trust, as it may save or share the readings.
