It is a very poorly designed and inconvenient app. They don't warn you about the many nuances and subtleties. They don't mention anything about their problems before you buy the subscription or after you have paid for it. It's like a game where you have to find all the problems with the service yourself. A huge problem for me has been the lack of an offline mode. Because of that, I am house-bound and all my workouts take place indoors. My rating is 1.
