Mobile app — no web demo. Run it with Expo Go from the repository.
Overview
An Expo / React Native app where users log meals manually or by photo. Google Gemini analyses the picture and returns structured macros; a chat assistant answers nutrition questions using the user's own profile as context. Auth, data and images live in Supabase.

- AI dietitian chat with history and user-aware system prompt
- Dashboard with calorie and macro rings, water tracker, supplements
- Onboarding with calorie goals (Mifflin-St Jeor), history calendar, EN/UK/RU
Engineering highlights
- Jest + jest-expo tests for the calculator, diary store and components
- EAS Build / Update configuration for OTA releases
