How It Works
1. Add your own API key — Google Gemini (free tier), OpenAI, Anthropic, or OpenRouter — or subscribe to Auto Mode and skip the setup
2. Snap, scan, speak, type, or enter your meal
3. AI identifies every food item and calculates nutrition
4. Adjust portions for accuracy
5. Track your progress over time
BYOK (Bring Your Own Key) — Free Forever Option
Skip subscriptions entirely by bringing your own API key. Google Gemini offers a free tier; with paid providers you pay them directly, typically a cent or two per scan. No middleman fees, no signup.
Privacy First
No account required. No data collection. Your calorie and nutrition data stays on your device and syncs only through your personal iCloud, if you turn it on. With your own key, photos go straight to the AI provider you chose. In Auto Mode they pass through our relay, which does not store your photos or your meals.
Perfect For
◉ Weight loss, muscle gain, or simply eating healthier
◉ Keto, vegan, low-carb, paleo, IIFYM — any diet
More Features
◉ Available in 14 languages
◉ iCloud sync across all Apple devices
◉ Metric and imperial units
◉ Works offline — history, manual entry, and stats need no connection
◉ Dark mode

The API keys do not work making this completely useless and non functional. The second you try to log food no matter how simple it just tells you something went wrong.
