AllergyTrace: Allergy Diary

You know you have allergies — but which allergens actually trigger your symptoms? AllergyTrace finds out, using real statistical analysis of your own data.

📊 THREE ANALYSIS LEVELS
• Simple: Clear interpretation in words — what triggers your symptoms?
• Detailed: Bar charts per symptom with concrete numbers
• Scientific: Statistical table with effect size (Cohen's d), Welch's t-test p-value, and Ordinal Logistic Regression for confounder adjustment

🎯 FLEXIBLE SYMPTOM TRACKING
• Create your own symptom fields — sneezing, itching, stomach pain, whatever you need
• 0-10 scale with color-coded sliders
• Multiple entries per day (morning, evening) possible
• Smart: app suggests matching symptom fields when you add a new allergen
• Date navigation for retrospective entries

🌿 136+ ALLERGENS WITH REACTION PROFILES
• Food (EU-14 main allergens + 40+ extended) — incl. lactose intolerance, gluten intolerance
• Animals (pet allergy), dust mites, mold, insect venoms, chemicals, medications
• Reaction profiles (onset, peak, duration) for automatic lag detection
• Cross-reaction info (e.g. Birch → Apples, Hazelnuts)

💊 58+ RELIEF MEDICATIONS
• Antihistamines, nasal sprays, eye drops, corticosteroids, bronchodilators
• Autocomplete with brand names (Zyrtec, Claritin, Flonase...)
• Effectiveness analysis: does cetirizine really help your birch pollen allergy?

🍽️ PRECISE FOOD TRACKING
• Product + amount instead of intensity (e.g. "cheese sandwich, 1 portion")
• Context capture (home, restaurant, cafeteria)

🔒 100% PRIVATE & OFFLINE
• All data stored only on your device — no server, no cloud
• PIN + Biometrics (Face ID / Fingerprint) protection
• Backup as JSON file — local or share externally
