Bests & Worsts Reviews from Amazon

I've used the single-area daily workout apps and was glad to see this addition to the series. The videos show correct form, and the written instructions are clear and useful. You can't customize the workout, but that's understandable in a free app and a good reason to pay the developer for the full version. Why not 5 stars? The workouts are silent except for the name of the next exercise. When you're on your belly doing one of the exercises, how are you supposed to keep track of repetitions? An audible count or metronome tone would be very helpful.
