Generally speaking I really like this app. But as of today Im deleting it from my phone and finding a different app. My only gripe about this app is the placement of the "end workout" button. I cannot tell you how many times Ive accidentally ended my workout because the button is literally on top of the "resume" button and is just too easy to hit accidentally. In order to go back to the point you were at, you need to fast forward and instead of going to each phase, it seems to have a weird time set for fast forward and reverse, so you cant get back to the stage you were at when you accidentally ended the workout. Everything else works as advertised and is an easy layout to follow.
