ChallengeLoop

We believe that every activity is more fun when it's a competition. ChallengeLoop is an iPhone app and website that makes it easy for you to challenge your friends and even yourself to anything. With ChallengeLoop, challenges are made into interactive experiences with photos, videos, real life prizes, comments and even rooting. Our mission is to be the best in the world at documenting, sharing, engaging spectators and telling the story of a competition from beginning to end. Join our beta list! www.challengeloop.com
