You can use the Frontier X device by itself or with our companion Android, iOS, or Apple Watch apps. 

Frontier X can also be connected as a Heart Rate sensor to all devices that are equipped with Bluetooth Low Energy (BLE) Technology, such as most Garmin watches, Wahoo Cycling Computers, Peloton devices etc.

However, it will only connect to one other device (smartphone or Apple watch or Garmin) at a time.
