A proof-based habit tracking app. Habits only count when you prove them — no more self-reported streaks.

Done. lets you create daily habits and requires proof of completion before marking them done. Proof methods include:

• Camera + AI — Take a photo and an AI model verifies it matches your habit
• Buddy verification — Invite a friend to confirm your completion
• Sensor data — Use device sensors (steps, health data)
• External APIs — Connect to Apple Health, Strava, etc.

Other features:

• Streak tracking (current and best)
• Flexible scheduling (daily, weekdays, weekends)
• Predefined habit templates organized by category
• Buddy system for mutual accountability
• Light and dark mode
• Onboarding flow for new users

• Framework: React Native + Expo (managed workflow)
• Language: TypeScript
• Navigation: Expo Router (file-based)
• Styling: TailwindCSS via NativeWind
• Backend: Supabase (PostgreSQL, Auth, Storage, Edge Functions)
• Camera: expo-camera
• AI verification: OpenAI (via Supabase Edge Function)
• Animations: React Native Reanimated + Gesture Handler

• Node.js
• npm
• Expo CLI (npm install -g expo-cli)
• A Supabase project
• An OpenAI API key (for AI proof verification)
