The Apple Watch OS allows you to access the integrated heart rate monitor. This means you are able to monitor and record your heart rate during a Runtastic activity using your Apple Watch.
You can view your heart rate either from the watch or the app on your phone.
If you are wearing a heart rate monitor strap, your heart rate will be measured using this device and not the Apple Watch.
Heart rate recording is supported by the following versions:
- watchOS3 and newer
