🍞 Gluten-free scanner app

Scan any food barcode and know in seconds whether it contains gluten (cereals) — under any of its 11+ label names. Free and independent: no ads, no sponsored products, an honest “Unknown” when the data is thin.

How it works

1 · Set your profile once — pick gluten (cereals) (and any other allergens) with optional severity per person in your household.

2 · Scan the barcode — Scallergy checks the ingredient list against every gluten (cereals) label name: rye, barley, oats, spelt, triticale, and more.

3 · Read one clear verdictAvoid (it's in the ingredients), Caution (may-contain warning), Unknown (we say so instead of guessing).

Frequently asked questions

How does the gluten-free scanner work?

Point your camera at any food barcode. Scallergy looks the product up (USDA FoodData Central, Open Food Facts, and community submissions), checks the ingredient list against 11+ gluten (cereals) label names, and shows one clear verdict: Avoid, Caution, Looks OK — or an honest Unknown when data is thin.

Is the app free?

Yes — Scallergy is free, independent, and has no ads. No brand can pay to look safer.

Can it guarantee a product is safe?

No app can. Scallergy is assistive: it shows its data source on every product, says Unknown honestly, and you should always check the printed label and follow your allergist's advice.

Scallergy is assistive, not medical advice — always check the printed label and consult an allergist. Data sources.
