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.

FEEL GOOD AFTER EVERY MEAL Living with histamine intolerance or MCAS means every food is a question mark. HistaScan gives you a clear, instant answer โ€” just scan. SCAN ANY FOOD, THREE WAYS โ€ข Barcode โ€” check any packaged product in seconds โ€ข Ingredient label (OCR) โ€” snap the label for an instant breakdown โ€ข Dish / plate photo โ€” analyze a whole meal from one picture HISTAMINE, OXALATES AND SALICYLATES Most apps only look at histamine. HistaScan rates all three, because people with MCAS frequently react to oxalates and salicylates too. KNOW YOUR DAILY LOAD Histamine is cumulative โ€” it's the total across the day that matters, not any single food. HistaScan tracks your daily histamine load against an allowance tuned to your sensitivity, so you can see how much headroom you have left. ALWAYS EXPLAINS WHY Every rating names the exact ingredients behind it, in plain language, with a lower-histamine swap when a trigger appears. No colour codes you have to guess at. BUILD YOUR SAFE-FOOD LIST Save the foods that work for you and pull them up instantly at the grocery store. TRACK SYMPTOMS, FIND YOUR TRIGGERS Log meals and reactions in one private timeline. Note antihistamines, DAO enzyme, and severity to spot the patterns behind your flares. DESIGNED FOR YOUR CONDITION Built for histamine intolerance, MCAS, mast cell activation, and low-histamine elimination diets. PRIVATE BY DESIGN No account required. Your diary, reaction logs, and saved lists stay on your device. Foods you scan are analyzed online. Free to start. Premium unlocks unlimited scans, instant meal-photo analysis, and advanced MCAS symptom insights. HistaScan is an educational tool and not a substitute for professional medical advice. Always consult a qualified healthcare provider.
