What it does
A pain diary made for your worst days
Large targets, high contrast and almost no typing. Add the details later, once the flare has passed.
Five-second logging
Tap a pain level and the spot on a body map — left, right, front and back. Triggers, pain types, medication and notes can wait.
Flare timer
During a flare, Home shows how long it has lasted. Tap “No pain now” when it eases.
Medication relief
Your pain before each dose next to your pain 30 minutes to 4 hours after it, for every medication.
Dose limits you set
A daily maximum and the hours between doses, with a count of where you stand. Ouch Log only counts; it never blocks a dose.
Patterns and trends
7, 30 or 90 days compared with the period before: flares, time of day, body regions, pain types, triggers and days of work or school missed.
Reports for your doctor
Add your visits and the questions you want to ask. PDF reports for any range, with your questions printed at the top, and CSV export of every entry.
How it works
From a bad day to a clear picture
Log while it hurts
Two taps on the level and the body map. On iPhone you can also log from a widget or Apple Watch without opening the app.
Look back
A calendar with a color dot for every day, and a one-page summary each month.
Walk in with proof
A reminder the evening before your appointment, with a report covering everything since your last visit.
