Simple and Cheap - Does 99% of what I need – Heart Graph Review

I use this to track my time in zones across multiple workouts with my Polar strap. I am not a workout warrior by any stretch, so I mostly just listen for the zone alarms and look back to make sure I am normalizing my effort across multiple (rowing, biking, HIIT, etc) workouts. It works, connects to Apple Fitness, imports data from the Assault Bike/RowErg/Garmin stuff I use, and is cheap to boot. We spend more than $3 on a coffee… The ONLY thing I would like to see (and i may have not figured it out yet) is just a big honking real time heart rate on the screen. I use another app that displays this alongside a bunch of other data, but I would really love a simple screen display that shows HR and maybe current or elapsed time….
