This app worked pretty well but saves your workout data and progress locally. If you ever need to delete and re-install the app because of a problem (as I have), you will loose all your settings and progress and restart the program at day 1. Also, since iOS 8, none of the data is saved even if youre signed in. The consequence is that you will start from the beginning every time you open the app.
