This app would have been an immediate joyful buy, but for these facts. (1) There is no interplay whatsoever with Apple Health, so Health will never know you did anything re this app. (2) #1 prevents other apps from keeping track of such activity so you will never see a calendar view, nor the impact, if any, via metrics reflecting otherwise documented physiological changes. (3) Presenting this as a sub, given 1 & 2, just underscores how blatantly ridiculousness the entire sub vibe has become. Bottom-line: a coulda been killah app, hobbled by an egregious combo of lazy coding and greed. Uninstalled per the disgust factor.
