Useful basic app

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, its hard to tell what set you are on.
