【實用健康app】Pushup Buddy|最夯免費app-綠色工廠好玩App

Press the start button and let Pushup Buddy measure and tell your progress on your pushup workout, using the proximity sensor. It detects when you rest between sets and tells you when you have rested long enough and makes a list of all the sets. Workouts are saved so you can compare them any time.
