Ridr

ridrapp.vercel.app — web build

Carpooling is usually arranged over text with no real way to confirm who's actually driving and no visibility once the car pulls away. Ridr fixes that by verifying every parent and student inside their own school's community, so rides only ever happen with people you already trust — parents can split driving days instead of doing it alone, and fewer cars showing up at pickup means less gas burned and less CO₂ in the air.

Each school gets its own verified community. Parents set which days they can drive, and the app matches them with other families on the same schedule — so pickups get split, not carried by one parent every day.

Tech stack

• React Native + Expo (~54.0.0), TypeScript, NativeWind/Tailwind for styling
• Supabase for auth, database, storage, and edge functions (supabase/)
• React Navigation (stack + bottom tabs)
• Sentry for error monitoring
• Jest + Testing Library for tests, with mocked RLS/scheduling/demo coverage

Getting started

npm install
npm start          # production app — talks to real Supabase

Other useful scripts (see package.json):

npm run demo        # in-memory demo mode, no backend needed — see docs/demo-runbook.md
npm run ios         # native iOS build via expo run:ios
npm run android      # native Android build via expo run:android
npm run web         # web build
npm test            # run the mocked/demo test suite
npm run test:live   # live RLS probe against a real Supabase project (needs env vars)

Read docs/demo-runbook.md before giving a live demo — it walks through the full signup → schedule → live trip → messages flow and calls out the exact gotchas from a real run.

Security & privacy

Every school is a verified, isolated community — Row Level Security policies enforce that rides, schedules, and messages are only visible within a rider's own school. See security-audit/ and legal/privacy-policy.md for details.
