RaceRunner vs Radius.fit

RaceRunner: the run-tracking app built by a runner who races, for runners who race. Spectators can track the progress of runners during races. Spectators can start and stop timing of runs. Spectators can send messages to runners which are read aloud by the runner's phone. RaceRunner can stop timing a run automatically after a certain distance, which is useful for the time trials that runners conduct in preparation for races. RaceRunner can track shoe mileage and warn when mileage limits are exceeded. Keep those racing flats fresh! The source code for RaceRunner is available on GitHub. Feel free to inspect the source code and offer changes to it. Continued use of GPS running in the background can dramatically decrease battery life.

Radius is an activity building app where you go out into the Actual World™ and record your activities, share them with friends, or compete in virtual races while your friends and family spectate in real time. CAPTURE - Radius can capture an activity you do in real time, plotting the course while monitoring speed, position and altitude changes. COMPARE - Radius is teaming up with your favorite race promoters to augment your race with a little more competition, make spectating easier, and keep you safe by allowing race promoters to watch for participants who wander off course. COMMUNITY - Radius groups people together based on proficiency. Gone are the days of the bad running partner or lame group ride. You know how you'll measure up before the event begins.
