MobiTiming

This is an app that near realtime starts stopwatches on multiple mobile phones, allowing timekeepers to record lap times and final times to the starters device. As it is dependent on devices and communication networks, errors could occur and the app should therefore not be used for official races.
The app is primarily intended for training and informal races, being teachers, trainers or others arranging a friendly race where a digital timekeeping is wanted. Consider the app as a supplement to using multiple stopwatches for races where individual timekeepers are tracking a lane or an athlete.
