Urban Sprout 🌱

Urban gardening app with plant care, AI advice, journal entries, and community marketplace.

Rebuilt from scratch as a native Expo / React Native app (TypeScript, expo-router) for Google Play. The original version was built on Base44; this version no longer depends on Base44.

Features

• My Plants – care info (built-in guide for common plants) and local watering reminders (expo-notifications)
• Ask AI – plant-advice chat via a Supabase Edge Function (AI key stays on the server; any OpenAI-compatible provider — Fireworks by default, OpenAI via AI_BASE_URL/AI_MODEL); free tier 5 questions/day
• Garden Journal – notes with camera/gallery photos
• Community Market – listings for cuttings, seeds and produce, with report and block user
• Account – sign in, privacy policy, restore purchases, delete account (Google Play requirement)
• Monetization – Sprout Pro subscription (RevenueCat → Google Play Billing) unlocks unlimited AI + no ads; AdMob banners for free users (test IDs by default)

Quick start

npm install
cp .env.example .env   # fill in Supabase keys
npx expo start

Ads and in-app purchases are native modules, so use a development build (eas build --profile development) rather than Expo Go to test them.

Project layout

• app/ – screens (expo-router)
• src/lib/ – Supabase client, auth, notifications, AI, purchases, ads
• supabase/migrations/ – database schema with Row Level Security
• supabase/functions/plant-advice – AI advice + daily limit
• supabase/functions/revenuecat-webhook – syncs Pro status to the database
• docs/SETUP.md – full setup: Supabase, RevenueCat, AdMob, EAS build, Play closed testing
• docs/PLAY_STORE_LISTING.md – store listing copy
• PRIVACY_POLICY.md

Security

• .gitignore prevents API keys, secrets and credentials from being committed.
• Never commit .env or any file containing secrets. Only EXPO_PUBLIC_* values (safe, public) are used by the app.
