Great workout app

This is the app I was looking for to run, specially after ver. 2 with adding my own music to the mix. There are only a few things developers can consider to make it perfect:
* With fitness level set to Meduim, I sometimes feel that workouts is not consistent one after the other. Sometimes its too easy, sometimes too hard, so I need to usually adjust to my levels.
* I wish other elliptical app was an in app purchase so that I could track calories and results all in one app and one place.
