Flare Diary is a gentle, flexible daily tracker for living with chronic illness. Whether you manage pain, fatigue, autoimmune flares, migraines, eczema, asthma or any long-term condition, it helps you keep an honest record of how you feel, in your own words. This is a personal log to help you notice patterns and prepare for appointments. It is for informational purposes only. It is not medical advice, a diagnosis, or a measuring device. Always consult a qualified healthcare professional. LOG YOUR DAY, YOUR WAY - Add your own symptoms and rate each from 0 (none) to 10 (extreme) - Mark where it hurts on a simple body map - Note your mood, the weather, triggers and medications - Add a free-text note for anything else TRACK MIGRAINES IN THE SAME DIARY - Turn on "Migraine attack" in any entry to log intensity, duration and pain side - Tick the features that matter: aura, nausea, light and sound sensitivity, throbbing, dizziness - Note whether you took an acute medication, so medication days are counted for you - Migraine attacks show on your timeline, in Insights and in the doctor report SEE YOUR PATTERNS - A color-coded flare timeline shows good days and hard days at a glance - Insights highlight which triggers tend to appear before a flare - Follow the average severity of each symptom over time READY FOR YOUR NEXT APPOINTMENT - Export a clean, one-tap doctor-visit report as a PDF - Or export all of your data as a CSV spreadsheet PRIVATE BY DESIGN - Everything stays on your device - No account, no sign-up, no tracking, no ads - Your health data is yours alone, and we never sell it Daily symptom logging is free, and your full history is always free, never locked behind a paywall.

OuchLog is a fast, private pain tracker and symptom diary for people living with chronic pain, migraine, fibromyalgia, arthritis and other long-term conditions. Log a flare in seconds, see what actually helps, and walk into your next appointment with proof. MADE FOR YOUR WORST DAYS ⢠Log a flare in about five seconds ā tap a pain level, tap where it hurts, done. ⢠Point to exactly where it hurts on a body map: left, right, front and back. ⢠Add triggers, pain types, medications and notes later, once the flare passes. ⢠During a flare, Home shows how long it has lasted. Tap "No pain now" when it eases. ⢠Log from Home Screen and Lock Screen widgets or your Apple Watch, without opening the app. SEE WHAT ACTUALLY HELPS ⢠Medication relief: your pain before each dose next to your pain 30 minutes to 4 hours after it, for every medication. ⢠Check-in after a dose: one notification asks how you feel now, and you answer right from it. ⢠Set your own dose limits ā a daily maximum and the hours between doses ā and see where you stand on each medication. OuchLog only counts; it never blocks a dose. ⢠A rolling 30-day counter of as-needed medication days, with a limit you set ā a gentle nudge to check with your doctor. FIND YOUR PATTERNS ⢠Trends over 7, 30 or 90 days, compared with the period before ⢠Flares: how many, how long they last, and the longest one ⢠Time of day, most affected body regions, pain types and triggers ā with the average pain level for each ⢠Daily impact: days you missed work or school, and days you cut back on activities ⢠Sleep and pain: connect Apple Health to compare your worst pain after short nights and long ones ⢠A calendar with a color dot for every day EACH MONTH, SUMMED UP ⢠Pain days, flares, medication relief and what changed since the month before, on one page ⢠An optional notification on the 1st of each month WALK IN WITH PROOF ⢠Add your doctor visits and the questions you want to ask ⢠A reminder the evening before, with a report covering everything since your last visit ⢠PDF reports for 7, 30 or 90 days, a custom range, or since your last visit ā your questions printed at the top ⢠CSV export of every entry PRIVATE BY DESIGN ⢠Your pain entries, notes and medications stay on your device. No account, no sign-up, and OuchLog has no server of its own: your entries are never sent to us. ⢠Apple Health is optional and off until you connect it. New entries are saved there as symptoms; sleep read from it stays on your device. ⢠Lock the diary with Face ID or your passcode. ⢠Works fully offline; export a backup whenever you like. ⢠No ads. EASY TO USE WHILE HURTING ⢠Large targets, high contrast, full Dynamic Type support ⢠20 languages Everything OuchLog shows is a pattern in your own log. It 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. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
