About

Chronic Pain Tracker & Diary

Features
Read full description

Your pain is real โ€” PainLog helps you show it in numbers. When a doctor asks "how bad, how often, where exactly?", memory blurs the worst weeks. PainLog is a fast, private pain diary: log each episode in seconds, watch the pattern appear on charts and a body map, and walk into your next appointment with the whole record in your hand. PainLog is built for the moment pain actually strikes. No account, no forms, no wellness quiz โ€” open the app, set the 0โ€“10 intensity, tap the body area and how it feels, done. The diary does the remembering so you can get on with your day. WHAT YOU GET โ€ข An episode logged in seconds โ€” intensity on the 0โ€“10 scale doctors use, body area, descriptors like sharp, burning or throbbing, duration and a note โ€ข A CSV report of every episode โ€” dates, scores, areas, types โ€” ready to hand to your GP, specialist or physio โ€ข Your last 7 and 30 days drawn as one intensity curve, so "it has been worse lately" becomes a line you can point to โ€ข A body map that shades the areas you log most โ€” tap one and your whole history filters to just that spot โ€ข A flare-up alert when you have logged at or above your own threshold on consecutive days โ€ข A daily check-in reminder at the time you choose, so bad weeks get recorded instead of half-remembered PERFECT FOR โ€ข Living with fibromyalgia, arthritis or nerve pain and tired of answering "on a scale of one to ten?" from memory โ€ข Back pain that comes and goes โ€” find out whether it is really improving or you are just having a good day โ€ข Preparing for a specialist referral, insurance claim or disability paperwork that needs dates and numbers โ€ข Judging a new medication or physio programme against what you actually felt, day by day WHY NOT JUST A NOTES APP? A note says "back was bad on Tuesday". PainLog says 7/10, lower back, sharp and shooting, 90 minutes โ€” and turns fifty such entries into daily averages, a trend line and a most-affected-areas map. That is the difference between telling your doctor a story and handing them data. PRIVATE BY DEFAULT Your diary stays on your iPhone. No account, no cloud, no server โ€” PainLog collects nothing and sends nothing. Your record leaves the device only when you choose to export it. FULL ACCESS PainLog requires Full Access, available as an auto-renewing weekly or yearly subscription or a one-time lifetime purchase. Full Access unlocks the complete app: unlimited episode logging, full history with editing, the body map, 7- and 30-day trend charts, flare-up detection, the daily reminder and CSV export. Prices are shown in the app before purchase; subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period, and can be managed anytime in your Apple ID settings. PainLog is a personal diary, not a medical device โ€” it records what you report and never interprets your condition. Download PainLog and log your first episode tonight โ€” your next appointment is closer than you think.
