Field notes
After pairing with a Polar H10 over Bluetooth, recording can begin automatically when the strap connects and continue in six-hour chunks, including with the phone locked. A one-tap mark is stored with the trace; the viewer places marks on a standard 25 mm/s × 10 mm/mV grid and includes the preceding 30 seconds. The homepage also describes an Easy mode with a single event button, intended for setup by a family member.
