Pantry & shopping
Track what you have on hand and generate a shopping list from low stock. Health OS does not yet read your food diary to update stock automatically — use Restock, Use, or Set below after you shop or cook.

Shopping preferences
Purchasing preferences only — Health OS does not make nutrition or ethical claims from these.
Copy a past day or meal
Reuse a previous day. Copies are added to the target — nothing is overwritten or deleted.
Saved meals
Save a logged meal as a reusable template, then add it to any day. Adding appends the saved items — nothing is overwritten, and editing a diary entry never changes a saved meal.
Recipes
Build a reusable recipe from your foods and set how much it makes, then log any number of portions. Logging saves a scaled snapshot — editing or archiving a recipe never changes entries you already logged.
Manual day totals fallback
Use yesterday-like totals as a starting point, then adjust before saving.

Review meal
Personal-catalog foods only, up to 20. Reload loses this list. Offline is draft only; reconnect never logs automatically.
Favorites and foods recently used for this meal appear first. Choosing a food always opens amount, unit, meal, and date confirmation.
Plate photo analysis off
Photo analysis is off. The photo stays on this device. Log each item you can see using search above.
Nothing is uploaded, read automatically, estimated, or saved. The photo is only an on-device reminder of what was on the plate while you log each item — amounts stay measured, never guessed. Health OS drops its in-app copy when you close this panel or leave Search, but cannot delete a copy saved by your camera, Photos, or the operating system.
Send this photo to OpenAI?
This cleaned photo will be transmitted to OpenAI once, for this one analysis. The cleaned photo is not stored by Health OS; neither are the prompt or raw answer. Health OS requests OpenAI not to store application state. OpenAI may still retain customer content in abuse-monitoring logs for up to 30 days. This attempt reserves US$0.25 from the monthly cap. What comes back is a rough estimate you must review — nothing is added to your diary automatically.
Estimated, not measured.
Nothing here is logged. Use “Find this food” on a component to search for it and confirm a real amount through the normal review flow.
Camera permission is denied for Health OS in this browser. Enable camera access in your browser or site settings to use live scanning — or type the barcode below instead.
The photo stays on this device. Automatic reading is off. No upload occurs. Manually copy the label into editable Review.
Health OS clears its in-app copy, but cannot delete a copy saved by your camera, Photos, or the operating system.
Send this label photo to OpenAI?
This cleaned photo will be transmitted to OpenAI once, to read the nutrition table. The cleaned photo is not stored by Health OS; neither are the prompt or raw answer. Health OS requests OpenAI not to store application state. OpenAI may still retain customer content in abuse-monitoring logs for up to 30 days. This attempt reserves US$0.25 from the monthly cap. Every value comes back into editable Review — nothing is added to your diary automatically.
Enter your own nutrition values per 100 g. You’ll confirm the amount, meal, and date before it’s added — nothing is logged until you tap Add.
Review food
Source: local cleaned label preview. Automatic reading is disabled: no photo is uploaded or sent to a provider. Every value is editable and user-reviewed. All eight nutrients are required because this diary cannot safely store Unknown as zero.
Copy one column exactly. Decimal commas are accepted. If the label gives salt instead of sodium, enter salt; conversion is checked server-side. Missing stays Unknown — required before Add.
Enter nutrients per 100 g.
