Bluetooth Heart Rate Monitor
I developed this Bluetooth Heart Rate Monitor because I wanted to collect heart rate data from my Coros arm band heart rate monitor while practicing martial arts. With my iPhone in the same room (within Bluetooth BLE4+ range), the app records heart rate data at my chosen interval and syncs it to Apple Health. It should work with any 3rd party BLE4+ heart rate monitor device.
Features include:
- Auto-start recording when the app launches
- Auto-reconnect if device goes out and back into range
- Runs in the background (while you are training)
- Battery percentage display (if supported by your device)
- Simple line graph showing recent heart rate readings
- Syncs with Apple Health
No unnecessary extras—just the essentials.
But if you need additional features, let me know—I’m happy to help!
