Useful basic app – Heart Graph Review

Connects reliably to BlueHR strap. Decent plotting and zone displays. Would like beeps at starts of sets to be louder; difficult to hear over music or the sound of a rower or AirDyne. Maybe a beep-beep-beep-BEEP 3-second countdown, too? Would like something like a set counter - if you set up an EMOM workout, it's hard to tell what set you are on. Still using the app after many more months. Two more feature wishes: * Many preprogrammed workouts have rep schemes including 21, e.g., 21-15-9. Can you make it possible to enter 21? * Sometimes I forget to turn off the app at the end of a workout. Can you add a UI for trimming away the end of the recording, from a selected spot?
