Good app but needs some work

This is a great app that keeps me going on the elliptical. I
Love the way the trainer encourages and guides you, and I love what it does with the beats! I just wish the developers would fix the bugs whereas the trainer sometime does not tell you what resistance to use and/or what pace keep up. This is app would be perfect if they can fix that.

Whats wrong with this thing? about BeatBurn Elliptical Trainer - Low Impact Cross Training for Runners and Weight Loss, v3.1.8
