Good idea, terrible app

My biggest complaint with this app was that swiping up to start as indicated did not work. It took about 20 swipes each day to get it started. Further, some days, it did not save my progress. The ab challenge program was great and the an was useful when it worked. Overall, the failure of this app to work as intended is disappointing.
