Social accountability mobile app built with Expo Router and Supabase. Create challenges, check in to keep streaks alive, and share photo “proof” with friends who can like and cheer you on.

• Proof/ – the Expo app source.
• .env – local environment secrets (kept out of git).

cd Proof          # app source directory
npm install       # install dependencies
npm run start     # choose iOS / Android / web

If Metro cache acts up: npx expo start --clear.

Create a .env in the repo root (already ignored):

PUBLIC_SUPABASE_URL=...
ANON_PUBLIC_KEY=...
SERVICE_ROLE_KEY=...
LETTA_API_KEY=...
LETTA_CHATBOT_MODEL=...
LETTA_IMAGE_VERIFIER_MODEL=...

• Goal tracking: challenges with start/end dates, frequencies, streaks, and check‑ins.
• Social feed: photo proofs with captions, likes/unlikes.
• Friends: send/accept requests; view friends’ active goals.
• AI assistant: floating Letta chatbot for quick coaching.

• npm run start – run Metro and select target.
• npm run ios / npm run android / npm run web – platform shortcuts.
• npm run lint – lint with Expo config.

Keep secrets in .env. Document Supabase schema/policy changes. Prefer typed expo-router routes for new screens.
