Catch every allergen. Down to a T. SYE 3.0 is the most clinically-aware allergen scanner on iOS. While other apps give you a flat yes/no, SYE gives you the clinical context that decides whether a food is safe for YOU specifically. ------------------------ WHAT MAKES SYE 3.0 DIFFERENT ------------------------ THREE RISK TIERS — Other scanners flatten allergen alerts into one red flag. SYE separates them: Contains (ingredient list), May contain (declared traces), and Facility-level (shared equipment). You decide per product, per allergen, what risk you accept. PER-ALLERGEN CLINICAL SEVERITY — Tag each allergen as Anaphylaxis, Intolerance, or Sensitivity. Anaphylactic to peanuts? Blocked at all 3 tiers, including facility-level. Lactose intolerant? Blocked on ingredients, warned on traces. This is how a doctor thinks about your allergies. CROSS-REACTIVITY AWARENESS (OAS) — 25 to 40 percent of pollen-allergic adults have Oral Allergy Syndrome. Allergic to birch pollen? You may also react to raw apples, hazelnuts, peaches — but cooked versions are usually safe. SYE encodes the AAAAI and EAACI cross-reactivity tables. No competitor app does. PROACTIVE FDA + CFIA RECALL ALERTS — Every day, SYE pulls the latest food recalls and matches them on your device against the products you scanned in the last 30 days. Get notified immediately when something you bought is recalled. REACTION LOG WITH PATTERN DETECTION — Track your reactions over time. SYE intersects ingredients across reaction-tagged scans and surfaces non-obvious patterns. Discovering a hidden sensitivity normally takes years and a specialist. EPIPEN EXPIRY TRACKER — Get notified before your EpiPen expires. Share your allergen profile with babysitters and family via the Share Allergen Card. IMAGE ALLERGEN DETECTION — Photograph any plate, homemade or restaurant, and get an AI-estimated ingredient list with allergen flags. With prominent precision disclaimers — because the difference between a label and a vision-AI guess is the difference between a guarantee and an estimate. RESTAURANT MENU SCAN — Photograph any restaurant menu. AI extracts every dish and flags items containing your allergens. ------------------------ HOW IT WORKS ------------------------ 1. Set your allergen profile — pick from 100+ allergens, set severity per allergen 2. Scan barcodes, restaurant menus, or photos of meals 3. Get instant verdicts based on the three-tier risk model and your severity settings ------------------------ PRIVACY-FIRST ------------------------ • Allergen detection on barcode scans is 100% deterministic — your label data is matched on-device against a bundled dictionary. No AI hallucination. • AI is used only for explicit image flows (Image Allergen Detection, restaurant menu scan). Each carries a precision disclaimer. • Recall alerts match on your device. Your scan history never leaves your phone. • Reaction logs are device-local. Pattern detection runs locally; no health data is uploaded. • CloudKit sync is end-to-end encrypted by Apple. • No accounts, no email, no tracking, no ads. ------------------------ PREMIUM ------------------------ Free: 3 personalized scans per day, full allergen detection, three-tier risk model, FDA recall alerts, reaction log, EpiPen tracker Premium: $2.99/month — unlimited scans, Aisle Scan, Quick Compare, Image Allergen Detection ------------------------ SYE is a decision-support tool, not medical advice. SYE detects allergens declared in ingredient lists; it cannot detect cross-contamination from shared kitchen equipment, fryers, surfaces, or airborne residue. For severe or life-threatening allergies (anaphylaxis), always confirm safety with the restaurant or product manufacturer before consuming. Always consult a qualified healthcare professional for dietary decisions. Built on Open Food Facts — the world's largest open food database, community-maintained.
