A simple, beautiful mobile app that uses AI to analyze food photos and provide macro nutrient breakdowns.

This app has been generated using Claude Code. It's meant for demo purposes.

1. Clone and install:

   git clone <repo-url>
   cd macro-photo
   npm install

2. Set up environment variables:

   cp .env.example .env
   # Edit .env and add your API keys

3. Run the app:

   # iOS
   npm run ios
   
   # Android
   npm run android
   
   # Web (for testing)
   npm run web
