Bluetooth Heart Rate Monitor

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 - New - Recording frequency expanded to 60 seconds - New - set min/max heart rate and now colour coded graph (Blue: Below Min, Green: Min-Max, Red: above Max).  - New - Displays the graph as a Live Activity on the Lock Screen and heart rate on Dynamic Island when in background No unnecessary extras—just the essentials.  But if you need additional features, let me know—I’m happy to help!
