Useful but could be improved
I mainly use this app to keep track of my weight training workouts. It works pretty well for this, but has one major flaw and one minor. First, if you are in the middle of a workout and the app is killed by the OS for whatever reason, it does not remember your progress when it relaunches. This is a huge frustration. There is no reason it can’t persist your in-progress workout and put you right back there when it relaunches. As it is I have to try to remember what I had filled in and start over. The second issue, which is more of a minor annoyance, is that the app will occasionally pause the music you have playing when you switch to it. I have to unpause my music multiple times throughout my workout.
