Understand your symptoms and finally spot what triggers your flares.
Symptom Tracker: Flare Log is a private symptom diary and flare log built for people living with chronic illness — migraine, fibromyalgia, IBS, chronic pain, fatigue, autoimmune conditions and more. Log any symptom in seconds, track the daily factors behind it, and let the app reveal the patterns you can't see on your own.
WHY YOU'LL LOVE IT
• Log ANY symptom on a simple 0–10 severity scale — fully customizable
• Track daily factors: sleep, stress, hydration, exercise, mood, medication and your own custom ones
• Discover correlations — see which factors line up with more severe (or milder) symptoms
• A complete history timeline of every check-in
• Export a clean, doctor-ready PDF report for your next appointment
• Smart daily reminders so your log stays consistent
• 100% private — your data stays on your device. No account, no sign-up, no tracking
BUILT FOR REAL LIFE WITH CHRONIC ILLNESS
Whether you're tracking migraines, joint pain, fatigue, brain fog, nausea, anxiety or flares of any kind, Symptom Tracker turns scattered notes into clear insight. The 20-second daily check-in fits into the hardest days.
SPOT YOUR TRIGGERS
The correlation engine compares your factors against your symptoms and highlights the strongest patterns in plain language — for example, "higher stress tends to go with more severe fatigue." These are statistical associations to explore with your doctor, not medical advice.
