Strava, a fitness tracking app, logs users’ movements as they cycle, surf, or jog. Last November, the app published an interactive map with over 13 trillion GPS points from all its users. The map was meant to impress potential users regarding the large number of people around the globe that were already using the app to track their fitness sessions.
