Ounce

Snap a photo of your meal. Ounce estimates the foods, portions, calories, protein, carbs and fat, then logs it. Fix anything with a tap or by typing "only half the rice".

Private by default. No account and no server. Your food log stays on your phone and in your own Android backup.
On-device AI on supported phones (Gemini Nano), so photos never leave the phone. Or use your own API key for Gemini, OpenAI, Claude or OpenRouter for sharper estimates.
Fast logging: one-tap camera, live barcode detection for packaged food (Open Food Facts), log by text, and a home-screen widget.
Progress: daily goals, weight tracking, charts, and CSV or Google Sheets export.

Calorie estimates from photos are approximate. Ounce is not a medical device and doesn't give medical advice.
