Very good
I do like the app a lot. The only downside is that it only counts your push up if your chest is practically touching your phone (which is placed under your chest so it can track your movement) so wide arm push ups are extremely hard to do for credit. I felt like I would be less than 3 inches away from the phone and it wouldn’t count it. However, the app is perfect for normal pushups, and the streak system and goals are very helpful for long term motivation.
