Challenge! Get out of your sofa and find a way to challenge your friends!
Chall is a video-sharing app for social challenges and video competitions. Record a video and join a competition or create a Chall for the community or your friends, and see how they respond. Challenge others to move on the edge or outside their comfort zone. Or even challenge someone for a good cause and constantly being updated of the outcome.
People love to challenge each other and they are more likely to try new stuff by a challenge from someone. Do the Ice bucket Chall for a good cause, do a new trick on your skateboard, get stronger and learn a new exercise in the gym, do a prank Chall, make a cover of your favorite song or tell a joke and Chall your friends to do the same.
