I feel like 45min to 60min high intensity interval training (HIIT) cardiovascular exercise (e.g. swimming, running, rowing, bicycling, stairs, elliptical, etc) would be cheaper and address a host of other health issues also. Include some compound weight lifting like pull ups, deadlift, squat, bench press, lunges, and core workouts like planks, and I bet outcomes greatly exceed whatever an app can provide.
