watchHR

watchHR is a professional heart rate monitoring and HRV app that provides real-time heart rate tracking, a smart alert system, and comprehensive workout data recording.

A low heart rate below a set low heart rate produces a single beep and vibration; a high heart rate above a set high heart rate produces two beeps and two vibrations; A high abnormal heart rate above a set abnormal heart rate produces three beeps and three vibrations, improving upon the inherent sound alerts of the Apple Watch.
