I purchased this app five months ago and it has gone better with every release. This app takes a different approach compared with other fitness apps. I have tried a few other ones and none of them have the concept of a workout session built in. The major win for this App in my opinion is the fact that it does not get in the way when you are at the gym. It does enough and helps you keep focus on your workout instead of fiddling around figuring out where/how to enter data. The developers really listen to users on their forum.
