Free · Designed for iPad. Not verified for macOS.
Free Apple Watch heart rate broadcasting for Zwift, MyWhoosh, and compatible bike computers.
HR Broadcast is a free app that helps you use Apple Watch heart rate in supported cycling apps and compatible bike computers.
Start the Watch App on Apple Watch to collect your live heart rate. Then keep HR Broadcast open on iPhone to relay that heart rate as a standard Bluetooth Heart Rate sensor. In your cycling app, choose the iPhone heart rate sensor. Some apps may show your iPhone name instead of the six-digit broadcast code.
Works with apps and devices that support Bluetooth Heart Rate sensors, including iPad or computer cycling apps such as MyWhoosh and Zwift, and some compatible bike computers.
Why HR Broadcast:
- Free to use.
- No subscription required.
- No extra chest strap required if you already use Apple Watch.
- Simple Apple Watch + iPhone workflow.
- Built for cycling apps and compatible bike computers that support Bluetooth heart rate sensors.
Notes:
- Requires Apple Watch for real-time heart rate collection.
- Keep HR Broadcast open on iPhone while broadcasting.
- The Apple Watch App may install automatically after installing the iPhone app. If it does not appear, open the iPhone Watch app and install HR Broadcast manually.
- Some bike computers, such as Garmin Edge 530, may not be supported due to firmware limitations. Please test with your own device.
