Great home interval workout app – J&J Official 7 Minute Workout Review

Really well-designed app for home or gym interval workouts. The video demonstrations are clear and helpful the first few time you do a new exercise. The only suggestion I have for improvement is to add a simple beep/tone for the exercises where you need to switch sides/legs/etc in the middle. Currently the timer flashes red to tell you to change, but if you have your phone in an armband for workouts it is difficult to keep an eye on the screen, so an audio cue would be really useful.
