AllergyLens instantly scans food ingredient labels and flags allergens that are dangerous to you — all in real time, right on your device. POINT. SCAN. KNOW. Point your camera at any ingredient list on food packaging. AllergyLens reads the text using advanced on-device OCR, then intelligently matches every ingredient against your personal allergen profile. Results appear in seconds with clear DANGER, WARNING, or SAFE indicators. HOW IT WORKS - Open the scanner and point your camera at an ingredient list - AllergyLens reads and parses every ingredient using Apple Vision OCR - A 4-stage allergen matching engine checks each ingredient against your profile - Instant results with color-coded severity: red for danger, amber for warnings, green for safe - Haptic and sound alerts warn you immediately when allergens are detected SMART ALLERGEN MATCHING AllergyLens goes beyond simple keyword search. The matching engine uses four stages of detection: — Direct match: catches exact allergen names — Derivative match: recognizes alternative names and derivatives (e.g., casein → dairy, edamame → soy) — Fuzzy match: catches OCR typos and misspellings using Levenshtein distance analysis — Semantic match: uses Apple's NLP word embeddings to find conceptually related ingredients 15 ALLERGEN CATEGORIES BUILT IN Peanuts, Tree Nuts, Milk/Dairy, Eggs, Wheat, Soy, Gluten, Shellfish, Fish, Sesame, Mustard, Celery, Lupin, Mollusks, and Sulfites — covering FDA, EU, and international allergen regulations. Over 400 ingredient aliases included. ADD YOUR OWN Have a rare or uncommon allergy? Add unlimited custom allergens with free-text matching. AllergyLens scans for those too. THREE SENSITIVITY LEVELS — Low: only exact matches, best for mild sensitivities — Medium: exact plus fuzzy matching, catches common misspellings — Strict: all matching stages including semantic analysis. Maximum safety. SCAN FROM PHOTOS TOO Can't point the camera? Import any photo of an ingredient label from your photo library. SAFETY FEATURES — Haptic vibration alerts when allergens are detected — Sound alerts with distinct tones for danger vs. warning — Emergency contact: store a contact and call them with one tap — Share scan results with caregivers, parents, or dining companions SCAN HISTORY & STATS Every scan is saved with full ingredient breakdown. Review past scans, see weekly statistics, and track how many alerts you've received. 100% PRIVATE. 100% ON-DEVICE. AllergyLens makes zero network calls.
