About Ouch Log: Pain Tracker & Diary
OuchLog is a fast, private pain tracker and symptom diary for people living with chronic pain, migraine, fibromyalgia, arthritis and other long-term conditions. WHY OUCHLOG • Log a flare in about five seconds — tap a pain level, tap where it hurts, done. Add triggers, medications and notes later, once the flare passes. • Your data stays on your device. No account, no server, no cloud, no tracking. FIND YOUR PATTERNS • Calendar with a color dot for each day • Trends: pain over the last 30 days, time-of-day, most affected regions • Trigger analysis — see which triggers show up most and the average pain level when they do • Your whole history, however far back you have logged FOR YOUR DOCTOR • Unlimited PDF report for any date range — formatted for a visit • CSV export of every entry • Pinpoint exactly where it hurts on a body map, front and back MEDICATIONS • One-tap dose logging with a quick amount picker • A rolling 30-day counter of as-needed medication days, with a limit you set — a gentle reminder to check with your doctor MADE TO BE USED WHILE HURTING • Large targets, high contrast, full Dynamic Type support • Home Screen and Lock Screen widgets to log without opening the app • Works fully offline; export a backup whenever you like • 20 languages OuchLog is a pain diary, not a medical device. It does not diagnose or treat, and does not give medical advice. Always talk to a healthcare professional about your symptoms and before making decisions about medication.
