SleepRecovery App Reviews

I just paid for this app, which is pretty rare based on a review that I saw, rarely a good idea. While I like the concept, the data presented is impossible to evaluate. The key metric, body recovery, is only a line graph with no numbers, and no way to evaluate what it means. Worse, there is no history, only seven data points which I infer to mean seven days. So what am I supposed to do with this? Also, the App Store description says the app provides recommendations based on your recovery score.

Doesn’t access data it needs to work properly. Going to abandon this. Not that useful.
