About
Sponsio makes accountability fun. Challenge your friends to daily habits — exercise, reading, meditation — and earn points for following through. Or make a quick prediction on anything: the game this weekend, whether your roommate finishes that book, who shows up late to dinner.
Two ways to play:
CHALLENGES
Pick a habit, invite friends, and check in daily with proof. Build streaks. Earn points when you follow through.
PREDICTIONS
State what you think will happen, set a points stake, and send it to a friend via iMessage. They take the other side. When it resolves, points are automatically awarded to the winner.
No money. No strangers. No prediction markets. Just you and your friends keeping each other honest.
FEATURES
• Send challenge invites right from iMessage
• Track streaks with animated badges
• Photo proof for check-ins
• Points history with every friend — see every exchange in one feed
• Confirm receipt of points with a quick tap
• Private and secure with iCloud
