I bought this app immediately. Needed a timer and was recommended by Jordon Yeoh. Ive programmed 4 workouts in so far and they are great! I dont stop the workout until its through (just finished one a little bit ago and typing this while resting). Its a life changer! I havent added music to it so far, but Im still tweaking it. The only complain I have is that it doesnt hold me at the end of my workout!
