SweatDebt turns fitness bets between friends into accountability. Challenge a friend, set a forfeit (loser does 100 burpees, wears a jersey, whatever), and when someone loses they have to upload video proof. What makes it different: - AI generates creative forfeits based on your sport - AI writes custom trash talk for your WhatsApp challenge - Friends vote to approve or dispute forfeit videos - Daily challenges with honour score system - Works as a PWA — no app store needed
