    Have looked for, and tried, a number of workout apps on WP and this is far and away the best one here. Comparable, and in some cases better, than JE Fit on Android. Excellent correspondence with the developer as well. Highly recommended...

    This is the best app there is for Windows phones. None of the others comes close.

    Very good app. Could use more exercises along with pictures/video for understanding correct form but otherwise very good.

    The input method is slow.

    Fantastic. Really pretty complete and customizable. Nice job - very well done. 2nd rating. It just keeps getting better. Now with body stats (measurements, weight etc) - very useful addition. The developers really went to great lengths to make sure this app is as complete and use full as possible. Great work!

    The best WP gym app - keeps things simple, easy to input and track info. I've used it for the last few months, in every workout, and it's helped keep me focused (the integrated timer is a real help). SkyDrive integration is great. The new cardio support, along with volume counts are very welcome additions to the app. Weekly exercise set and rep totals would be nice to have quick access to, in addition to drop set, super set, etc... support. All in all, a great lifting app and definitely worth the money. Updates have been fairly frequent. Buy it and support the developer!
