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.
