Every habit app lets you check a box and lie to yourself. UPROOF doesn't. Submit a timestamped photo proving you did the work — every single day. Miss your deadline? You pay a real fine. And here's the twist: your failure resets your entire group's streak. This is a shared responsibility. Your group votes to approve or reject your proof photos. All decisions are democratic — no admins, no shortcuts. Willpower fades. But when your money and your friends' streaks are on the line, you show up.
