Betcha — Challenge Friends

New: post updates and videos, add side goals like "no soda", see your group's dashboard, and play on iPad and iPhone Duo. Still friendly. Still no real money.

Betcha turns "bet you can't" into a friendly challenge. Make a wager with friends, track it together, and keep an honest record of who owes what.

ONE-SHOT BETS Who wins the game, who finishes first, who's right. Call the winner, and someone else confirms.

GOAL CHALLENGES "Gym 4x a week", "run every day", "read 30 pages". Everyone checks in, with photos if you want proof. Hit a weekly target, race to a number, or see who logs the most.

TEAMS Split into two teams and add up everyone's check-ins. The losing team shares one IOU, or everyone owes separately.

FAIR PLAY Results need someone else's confirmation, edits need everyone's OK, and questionable check-ins can be disputed.

PERSONAL GOALS Go solo with a reward for pulling it off and a penalty for slacking.

THE LEDGER See who owes what at a glance. Mark things paid and clear them when they're settled. Or skip stakes entirely and play for bragging rights.

Betcha never handles money. It's an honor-system ledger between friends.
