A mobile app that analyzes your basketball shot using Gemini and MediaPipe.

• mobile-app/: Expo (React Native) app.
• backend/: FastAPI Python server (Analysis Engine).
• prototype/: Original Python proof-of-concept.

1. Create a project at supabase.com.
2. Go to the SQL Editor in your Supabase dashboard.
3. Copy the contents of backend/schema.sql and run it to set up the tables and security policies.
4. Get your URL, Anon Key (for App), and Service Role Key (for Backend).

The backend handles video processing, calling Gemini API, and running MediaPipe.

1. Navigate to backend: cd backend

2. Create virtual environment (optional but recommended):

   python -m venv venv
   # Windows
   .\venv\Scripts\activate
   # Mac/Linux
   source venv/bin/activate

3. Install dependencies:

   pip install -r requirements.txt

4. Set up Environment Variables:

   • Create a .env file in backend/
   • Add your keys:

     GEMINI_API_KEY=your_gemini_key
     SUPABASE_URL=your_supabase_url
     SUPABASE_SERVICE_ROLE_KEY=your_service_role_key
     

5. Run the server:

   uvicorn main:app --reload --host 0.0.0.0 --port 8000

The frontend allows recording/uploading videos and viewing results.

1. Navigate to app: cd mobile-app

2. Install dependencies:

   npm install

3. Set up Environment Variables:

   • Rename/Create .env
   • Add Supabase keys:

     EXPO_PUBLIC_SUPABASE_URL=your_supabase_url
     EXPO_PUBLIC_SUPABASE_ANON_KEY=your_anon_key
     

4. Important: Update Backend URL

   • Open app/index.tsx
   • Update BACKEND_URL to your machine's IP address if testing on a real device.
   • Use http://10.0.2.2:8000 for Android Emulator.
   • Use http://localhost:8000 for iOS Simulator.

5. Run the app:

   npm run ios
   # or
   npm run android

1. Auth: User logs in or signs up via the Mobile App.
2. Input: User picks a video.
3. Processing:
   • App uploads video to http://<backend>/process-video with Auth Token.
   • Backend verifies user.
   • Backend uploads video to Supabase Storage.
   • Backend uploads to Gemini for analysis + runs MediaPipe.
   • Backend saves results to Supabase Database.
4. Result: App displays results.
