Heart Control: Chest Strap HRM

Heart Control is a Bluetooth chest strap and heart rate band monitor for BLE HRM belts. Wear a BLE chest strap (heart rate chest band / HRM belt) and connect over Bluetooth Low Energy. Heart Control works with external heart rate sensors that expose the standard Heart Rate Service. It records live BPM and, when your strap provides beat-to-beat data, RR intervals for long sessions, training, and everyday wellness monitoring.
