Allergen Signal

Food label allergen checker

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Pick the allergens you avoid, then scan a barcode or photograph the food label. Allergen Signal shows what the label declares and what it warns about. Your allergens. A clearer signal. Allergen Signal is a careful food-label assistant for people who check packaged food for allergens - for themselves or for someone in their household. BUILD YOUR PROFILE Choose every allergen you look for: the common allergens plus each individual tree nut, the way Australian labels name them. The profile stays on your device. CHECK A PACKAGED FOOD - Scan a barcode to look up community-supplied ingredient and allergen data from Open Food Facts - Or photograph the ingredients, "Contains" and "May contain" sections - AI reads the label text and matches it to your profile - Or save a manual note for a product you have already checked yourself FOUR CLEAR SIGNALS Every check ends in one of four results: a profile allergen is declared, a cross-contact ("May contain") warning, no profile allergen declared, or unable to confirm - with the evidence found and what to check next. SEARCHABLE HISTORY Recent checks are saved on your device so you can find a product again. PLANS Free includes 5 barcode checks and 5 AI photo reads a month. Basic, Pro and Plus monthly subscriptions raise the monthly allowances (25, 75 or 150 of each). Subscriptions renew automatically each month unless cancelled at least 24 hours before the period ends, and can be managed in your App Store account settings.
