Spar lets you challenge your friends to build healthy habits in a super effective, fun, and social way. Read more books, hit the gym, learn an instrument... challenge your friends to anything.
When you do the activity, you post fun video check-ins for the group to see. Go you!
If youve got money on the line and fail to check-in, you pay a pre-set amount to the group pot -- when the challenge is over, the winner gets all the money!
Want to get fit? Try 50 push-ups a day, for 1 month, with a $10 penalty. You wont miss much!
Start a challenge with your friends today. Get better together -- or take their money!
