Allergy & Symptom Diary

**Stop guessing what's triggering your allergies.**

Allergy Diary is the modern food + symptom + environmental tracker that finally connects the dots. Log what you eat, how you feel, what medications you take, and the air/pollen around you — then let AI spot the patterns no paper diary ever could.

**🌿 Built for real allergy sufferers**

Doctors prescribe symptom diaries before allergy testing, but paper journals get abandoned within a week. Allergy Diary is the friction-free, modern alternative — designed for adults living with food intolerances, eczema, IBS, hay fever, chronic urticaria, and undiagnosed sensitivities.

**🤖 AI Correlation Engine — the differentiator**

Tap "Run AI Analysis" and our engine reviews your last 30 days of entries to surface patterns like:

• *"Your headaches show a 73% match with dairy intake within 24 hours."*
• *"Skin flare-ups correlate with high tree-pollen days."*
• *"Symptom severity drops on weeks with low PM2.5 readings."*

Each result includes a confidence percentage, sample size, and plain-English explanation — never a diagnosis, always a starting point for your conversation with a doctor.

**📋 Doctor-ready PDF reports**

Generate a chronological PDF of your food, symptom, and medication entries — pre-formatted, with your profile and known allergies at the top. Email it to your allergist, immunologist, GI doctor, or dermatologist before your next appointment. No more reciting memory in the exam room.

**🌬️ Unified triggers in one timeline**

Most apps track either food OR pollen — Allergy Diary unifies both:

• Food entries with ingredient lists and meal types
• Symptoms with severity, body location, duration
• Medications with dose, route, reason
• Live air quality (AQI, PM2.5, PM10, ozone) via Open-Meteo
• Tree, grass, weed pollen levels for your city

**🔒 Privacy-first**

Everything lives on your device by default. Optional Google sign-in syncs your diary to a private Firebase backup — only you can access it. Never sold to advertisers.
