【實用健康app】My Racetime Tracker|最夯免費app-綠色工廠好玩App

My RaceTime Tracker is an app designed with a race-runner in mind! Not only does it allow runners competing in races to track their speed and milestones, but it also posts, texts, and tweets selected family and friends your time and location throughout the race.Continued use of GPS running in the background can dramatically decrease battery life.
