"What about my miCoach device? Can I use it with Runtastic?
The miCoach family of devices were built specifically for use with the miCoach platform. Their use with the Runtastic platform will be limited. See below for more details on your specific device:
Fit Smart: can be used with Runtastic as a heart rate monitor
Smart Run: this is a stand alone device and cannot be used with Runtastic
HRM Bluetooth: can be used with Runtastic as a heart rate monitor
SPEED_CELL Bluetooth: cannot be used with Runtastic
X_CELL: can be used with Runtastic as a heart rate monitor
You will still be able to use the full functionality or your devices with the miCoach platform and apps until the service stops on 31 Dec 2018. If you have chosen to migrate to Runtastic any workouts you complete with miCoach will be automatically synced to your Runtastic account too."
