What it does

Food data: 17,000+ foods from government nutrition databases are built in. Scan a barcode or search packaged products, and download your country’s product database to do both offline.
Rings for the day: Calories, protein, carbs and fat as rings with what is left inside, and a week strip to move between days.
Without opening the app: Widgets on the Home Screen and Lock Screen, your usual from Control Center, and Siri for what is left today.
Apple Health and iCloud: Food is saved to Apple Health as nutrition, and your log syncs through your own iCloud between iPhone and iPad.

Questions

Where does the food data come from?: Generic foods come from government nutrition databases in the US, the UK and Switzerland. Packaged products come from Open Food Facts, an open database anyone can add to.
Does my data leave my device?: Your log syncs through your own iCloud and your food goes to Apple Health. A barcode you scan, or the words of a search you tap, go to Open Food Facts to find the product. None of it reaches us.
Do I need an account?: No. There is no sign-up, no ads and no tracking.
