Hey Product Hunt! I'm the maker of UPROOF. Here's the problem I kept running into: I'd download a habit tracker, check boxes for 3 days, then quietly abandon it. Sound familiar? 92% of people fail their resolutions. Every habit app I tried treated willpower as the solution — but willpower is the problem. So I asked: What if quitting actually cost you something? UPROOF was born from one insight — humans don't sustain change alone. We need skin in the game and people who depend on us. That's why every feature revolves around three pillars: 1. Photo proof (no fake check-ins) 2. Real fines that escalate ($1 → $5 → $10) 3. Shared responsibility (your failure resets everyone's streak) The most interesting thing that happened during development: I tested the group streak mechanic with friends, and the social pressure was way more powerful than the money. Nobody wanted to be "that person" who broke a 30-day streak for everyone. The democratic voting system came from real frustration — I hated apps with group admins who had all the power. In UPROOF, every decision (approving photos, changing rules, kicking members) requires a majority vote. Built with React Native + Expo, powered by Supabase, available in 11 languages from day one. I'd love to hear what you think — and if you try it, let me know which habit you're proving first!
