Several things are frustrating with this app: no dark mode(!) - sleep score graphic isn't zoom-able - no fitness tracking for custom time period - no colour themes - no quick way to see when your extreme values for bpm occurred, you have to try and hit the graph just right... Weirdest thing encountered so far: got my highest body score after a week in bed with the flu. I usually run 5km, 4 times a week and visit the gym 5 or 6 times a week, but my body is 'better' after being ill for a week?
