More reliable GPS. BoxBox starts timing on a valid fix instead of holding out for a full lock, with a clear "waiting for GPS fix" state so you're never staring at a blank map. Your phone's GPS previews the track while a RaceBox is still warming up.

Recording that doesn't quit. Sessions keep recording with your phone locked in a pocket, and resume cleanly if a RaceBox drops out.

Plus: share BoxBox with friends from the home screen, create a track and use it right away, and smoother session maps and graphs.
