AllergAI helps you find the foods behind your symptoms. Scan a meal and AllergAI identifies the food and flags possible allergens in seconds. Log how you feel, and over time it triangulates the patterns connecting what you eat to how you feel, so you can have a more informed conversation with your doctor. WHAT YOU CAN DO - Scan food with your camera and get instant allergen flags - Look up packaged foods and dishes, even by brand name - Log symptoms, with optional AI photo reads - See trends and a personalized view of your likely triggers - Export a clean, physician-ready PDF for your appointments - Learn from a built-in education library on common allergens BUILT AROUND YOUR GOALS Tell AllergAI what you are working toward, finding hidden triggers, managing a known allergy, or eating out with more confidence, and it tailors your experience from day one. PRIVATE BY DESIGN Your food and symptom logs are stored on your device. IMPORTANT AllergAI is an informational tool, not a medical device. It does not diagnose, treat, or prevent any condition, and it can miss hidden or trace ingredients. Always check packaging and ask staff, and never rely on AllergAI for an allergy that could be severe. For any serious reaction, use epinephrine if prescribed and call emergency services. Always consult your physician about allergies and before making medical decisions. SUBSCRIPTION AllergAI offers a 3-day free trial, then an auto-renewing subscription (weekly, monthly, or yearly). Payment is charged to your Apple ID. Cancel anytime in Settings at least 24 hours before renewal.
