About this app
Lergy is a calm, intelligent food allergy and intolerance tracker that helps you identify which foods trigger your symptoms - automatically. Log your meals, track your reactions, and let Lergy's pattern detection engine find the connections you've been missing. -- FOOD DIARY -- Log every meal in seconds with ingredient tagging. Add photos, notes, and meal context. Lergy automatically matches your ingredients against 15 allergen groups including dairy, gluten, eggs, soy, peanuts, tree nuts, fish, shellfish, sesame, FODMAP, histamine, sulfites, nightshades, caffeine, and alcohol. -- SYMPTOM TRACKER -- Record symptoms by category: digestive, skin, respiratory, neurological, musculoskeletal, and more. Rate severity, note duration, body locations, and context. Build a precise, timestamped symptom history. -- PATTERN DETECTION -- Lergy cross-references your food diary with your symptom log and surfaces correlations automatically. See which ingredients appear most frequently before your worst reactions. No guesswork, no elimination-diet intuition - just data. -- ELIMINATION DIET GUIDE -- Follow a structured elimination phase, then reintroduce foods one by one with Lergy tracking the results. Know definitively what you can and cannot eat. -- DOCTOR REPORT -- Export a professional PDF health report to share with your allergist, gastroenterologist, or GP. Includes full symptom history, meal logs, correlation analysis, and timeline. -- DESIGNED FOR CLARITY -- Warm, calm interface designed to reduce anxiety around food. Not clinical, not scary - a thoughtful companion for your health journey.
