Other Bluetooth HR Sensor · Free Android beta

Turn your Bluetooth heart-rate sensor into live cardio guidance.

Many heart-rate straps, armbands and wearables transmit live heart rate using the standard Bluetooth Heart Rate service. If your device broadcasts that signal, ZoneCue Cardio may be able to turn it into proactive workout guidance.
