Your neurologist asked for three months of records. Most apps want an account first, then walk you through a questionnaire while your head is pounding. This one asks for one number.
Open the fan, tap the level, save. Three taps and it is folded away.
What it does
• Log an attack in 3 taps — intensity is the only required field
• Optional details when you have the energy: type (migraine, tension, cluster), how long it lasted, medication and whether it helped, triggers like sleep, stress, food, alcohol, caffeine, weather, screens, hormones
• Calendar heat map — each day takes the colour of the worst headache you logged, so a month reads at a glance
• MIDAS questionnaire with your grade I–IV, the disability scale neurologists use
• PDF report for your doctor — 30 days, 90 days or everything: summary, MIDAS grade and a full table of entries, straight to the share sheet
• Edit or delete any entry; the whole app works offline, airplane mode included
Who it is for
People keeping a headache or migraine diary because a doctor asked for one. People who tried a bigger tracker and quit in week two. People who get a headache at 3 a.m. and want the screen gone in ten seconds.
Your data stays here
No account, no sign-up, no cloud. Entries live in local storage on this phone and are never uploaded. Nothing to delete from a server later, because nothing was ever sent there.
The doctor report and the MIDAS score unlock by watching one short video — no subscription, no paywall.
Headache Diary is a diary, not a medical device. It does not diagnose, treat or predict anything. Sudden thunderclap pain, the worst headache of your life, or pain with fever, confusion, weakness or changes in speech or vision: get emergency help, not an app.
