Suspect food allergies but haven't identified the culprit? Suffering from chronic hives, bloating, or skin rashes and looking for patterns? Allergy Food Diary helps you log meals and symptoms on-the-go to uncover hidden correlations completely offline. By running a local, simplified Apriori association rules algorithm, the app calculates confidence and precursor rates to point out which foods are most likely triggering your flare-ups. WHY PAY FOR ALLERGY FOOD DIARY? Unlike generic food diaries that only track calories, Allergy Food Diary is built from the ground up for allergy tracking. For a single one-time lifetime purchase of $2.99 (after a 7-day free trial), you get advanced analytics tools, customizable analysis windows, and professional doctor-ready PDF exports. No monthly subscriptions, no ongoing costs. CORE FEATURES: 1. QUICK-LOG COMMON ALLERGENS: Speed-tag the Big 8 common food allergens (Egg, Milk, Peanut, Tree Nuts, Wheat, Soy, Fish, Shellfish) + enter custom food tags. 2. SYMPTOM TIMELINE: Log occurrences (hives, rash, bloating, sneezing, diarrhea) with customizable severity colors (Mild, Moderate, Severe). 3. LOCAL CORRELATION ENGINE: Uncover stats like "75% of Hives flare-ups were preceded by Mango consumption in the last 24 hours." 4. DOCTOR-READY REPORTS: Export a beautifully formatted PDF summarizing timeline logs and correlation rules to share with your allergist. 5. 100% PRIVATE & OFFLINE: Your sensitive health data never leaves your iPhone. All logs and analytics run locally in Core Data. * MEDICAL DISCLAIMER: This app is a tracking and correlation tool and does not constitute medical advice or diagnosis. Always consult a physician or allergist before making major dietary adjustments.
