Is Yumizo’s barcode scanner free?

Yes. Barcode scanning is unlimited for everyday use on Yumizo’s free plan, and so is searching the food database. You don’t need an account to start.

Where does Yumizo’s barcode data come from?

From OpenNutrition, a public food database, and, for barcodes it doesn’t have, Open Food Facts. Both are shared under the Open Database License. Only the barcode number is sent to Open Food Facts.

Can I scan a nutrition label instead?

Yes. Choose LABEL and point the camera straight at the label, and the AI reads it. A label scan counts as one of the free plan’s 2 AI logs a day.

How to scan a barcode

Tap the plate in the middle of the placemat on Home.
Choose BARCODE and hold the stripes in the frame. Yumizo scans on its own, no button needed.
Check the serving, change it if you ate more or less, and save.

Where the numbers come from

Barcodes are looked up in our own copy of OpenNutrition, a public food database. When a barcode isn’t there, our servers ask Open Food Facts, and only the barcode number is sent. Both databases are shared under the Open Database License. Our food data page explains how we clean them.

A label is a manufacturer’s figure, and recipes change, so check the serving size against the packet in your hand.

When a barcode isn’t found

Scan the nutrition label instead, and the AI reads it for you; a label scan counts as one of the free plan’s 2 AI logs a day. Or add the food yourself from its label. It’s saved to My foods, so next time it’s one tap.

For everything without a barcode

A home-cooked dinner has no stripes. Count it from a photo or say what you ate, and it lands in the same diary. Start on the Yumizo calorie counter home page.
