Ouch Log: Pain Tracker & Diary
Chronic pain & symptom log
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
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.
