Very hard to use. My phone still goes to sleep even when the app is running. And when it goes to sleep it stops notifying you of when you need to change pace. So basically you have to keep up with everything yourself. You have to struggle to keep up with time, get your phone open, adjust the treadmill (if thats what your using) all the while the seconds are ticking away in each cycle while youre supposed to be exercising. Because it doesnt pause while you are adjusting either. Disappointed!!!!
