30 Day Ab Challenge - Amazing 6 Pack Abs Workouts Examine App

First of all when launching you see level "NaN" which is the most junior of programming errors. Secondly, the app does not allow me to even start a workout. I tried logging in but that just prompted me to upgrade to pro. In the end I couldn't even start a workout. Sad....

Good app

I wanted to try this app and really liked it till I reached day 7 on day 7 I started my work out and did the sit ups when I hit next the app closed then it rest all the stuff I did. Wouldn't want to purchase it if that is the way it works.

Ok so far
