🥜 Peanuts allergy scanner app

Scan any food barcode and know in seconds whether it contains peanuts — under any of its 10+ 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 peanuts (and any other allergens) with optional severity per person in your household.

2 · Scan the barcode — Scallergy checks the ingredient list against every peanuts label name: groundnut, groundnuts, arachis, goober, monkey nut, and more.

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

Frequently asked questions

How does the peanuts allergy 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 10+ peanuts 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.
