Discover which foods trigger your symptoms. Log meals, track reactions, and let Lergy's pattern engine do the detective work.
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 use the guide to plan reintroducing foods one at a time with your clinician. Your meal and symptom logs are ready to bring to that conversation.
-- DOCTOR REPORT --
Export a professional PDF health report to share with your allergist, gastroenterologist, or GP. Includes your full symptom history, meal logs, and flagged food triggers for the period.
-- DESIGNED FOR CLARITY --
Warm, calm interface designed to reduce anxiety around food. Not clinical, not scary - a thoughtful companion for your health journey.
