Zeyti: Food Allergen Scanner
Halal, Kosher & Allergy Check
Only for iPhone
Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.
iPhone
Scan a barcode or the ingredient label and see whether a packaged food fits your allergies, diet, and halal or kosher needs. Everything runs on your device.
Zeyti reads ingredient labels for you. Scan a packaged food's barcode or point your camera at the ingredient list, and Zeyti checks it on your iPhone against the restrictions you set: allergens, diets, and beliefs.
WHAT ZEYTI CHECKS
• Allergens: gluten, dairy, egg, soy, peanut, tree nuts, shellfish, and more
• Diets and lifestyle: vegan, vegetarian, and other preferences
• Halal and kosher: read from the label
• Your own keywords: watch for any ingredient you want to avoid
CLEAR, HONEST RESULTS
Zeyti reports what it found. It never calls a product "safe". A green "No known restrictions found" means nothing in the product data matched your profile. Matches are colour-coded by how serious you marked them: amber for an intolerance, red for an allergy. Ingredients are highlighted inline so you can see exactly what was flagged.
TELL AN ALLERGY FROM AN INTOLERANCE
Mark each restriction as an allergy or an intolerance. Zeyti colours every match by that severity, so a true allergy is easy to spot.
HONEST ABOUT HALAL AND KOSHER
When a label declares a product halal or kosher, Zeyti shows the claim and notes that it comes from the label. Zeyti does not certify it. Uncertain ingredients, like gelatin of unknown source, get flagged so you can check them yourself.
PRIVATE BY DESIGN
Everything runs on your device. Label reading uses Apple's on-device text recognition, so your photos never leave your iPhone. There are no accounts and no tracking. Only the barcode number leaves your device. It goes to Open Food Facts to look up the product.
SCAN HISTORY AND REFORMULATION FLAGS
Save the products you rely on. Zeyti keeps a history you can revisit. When a saved product's ingredient list changes, Zeyti flags it in your history. A recipe that was fine can change without warning.
FREE AND PRO
Barcode scanning is free and unlimited. Zeyti Pro adds unlimited ingredient-label scanning for products that have no barcode or are missing from the database. Pro includes a 7-day free trial and Apple Family Sharing.
IMPORTANT
Zeyti reads ingredient labels and cannot guarantee accuracy. Labels change and recognition can miss text. Always verify with the manufacturer if you have a severe allergy. Halal and kosher status is read from the label only and is not independently certified.
