AI MEAL ESTIMATION
Photo to macros in seconds.
Aim the camera at a plate. The AI identifies items, estimates portions, and returns calories, protein, carbs, and fat. Every estimate carries a confidence indicator, and every value is editable before you log.
Works with home cooking, restaurant plates, takeaway, and multi-item platters.


AI LABEL SCAN
Packaged food. Label only.
Point the camera at a nutrition facts panel. The AI reads the numbers directly off the label. No database lookup, no ingredient matching, no guessing.

BARCODE
Three million products. Offline after first scan.
OpenFoodFacts powers instant lookups. Results cache locally, so a product you scanned once is yours forever. No internet required on repeat scans.
No AI credit spent. Barcode is the fastest path when the product has a label.

ONYX
Grounded in your data.
Onyx is a precision nutrition copilot. It is grounded in your real food log, your weight trend, and your goals. Ask about a week, a macro, a plateau. Onyx can also take action inside the app: plan a day, generate a recipe, adjust a goal.
No wellness fluff. Neutral tone. Your diary never leaves your device without consent.

The tenet
No ads. No account wall. Your data stays on your device.
