Every attack at a glance
The calendar is colored by pain level, so a bad month is obvious in a second. Attacks that last for days merge into one bar.
Migraine & headache diary for iPhone
Log a migraine in 20 seconds.
Bring your doctor real answers.
Your neurologist asks you to keep a headache diary for one to three months. MigNo is built to be filled in mid attack: pain level and time, that is all. Triggers, pressure and painkiller days add up on their own.

The problem
“How often does it happen?”
Most people guess.
By the appointment every attack has blurred into “it hurts often, somewhere here.” Paper diaries get abandoned in a week, because nobody fills in a table while their head is splitting. And the details that matter most, painkiller days and what came before an attack, are exactly what memory loses.
From memory
“Maybe twice a week? Mostly on the left. Ibuprofen works… sometimes.”

What you get
A diary you can keep
on your worst days
Painkiller day counter
9days of 30 · threshold 10
Taking pain relievers 10 or more days a month can keep the headache going. MigNo counts the days, so you can show the number to your doctor.
One question at 9:30 PM
Answer right from the lock screen. Pain free days are data too: without them nobody can count how often attacks happen.
Pressure, sleep and cycle fill themselves in
Pressure change
A drop of 6 hPa or more over 24 h: attacks happen 2.6 times as often
Barometric pressure at the onset of every attack, plus sleep and cycle from Apple Health. No manual input.
See what comes before an attack
Triggers ranked by how often they show up. Honest wording: what coincides, not what causes.
Attacks that last for days
Open it, close it, and every day inside is counted with its own pain level.
Two fields while it hurts. Everything else when the pain lets go.

Designed for light sensitivity
Dark on purpose,
because bright screens hurt
Most people with migraine are sensitive to light during an attack. MigNo has no bright white surfaces and no glowing red or yellow. Text sits at 9:1 contrast instead of 17:1: easy to read, gentle on the eyes. Even the pain scale is muted.

FAQ
Questions, answered
Is MigNo free?
The diary is free forever with no limit on records: logging attacks, medications, triggers, the calendar, reminders and data export. Premium adds trigger analysis, the PDF report for your doctor, medication comparison and sync. It costs $3.99 a month or $24.99 a year with a 7 day free trial, or $59.99 once.
Do I need to create an account?
No. MigNo works without registration. Your records stay on your iPhone until you turn on iCloud sync yourself.
How long does it take to log a migraine attack?
About 20 seconds. Only the pain level (0 to 10) and the start time are required. Location, symptoms, triggers and medication can be added later, once the pain lets go.
What is in the report for my doctor?
A one, two or three month summary: days with headache, average pain level, days with painkillers, every medication and how well it worked, the most frequent triggers and your MIDAS score.
Does MigNo track barometric pressure?
Yes. When you allow location, MigNo records the pressure at the onset of each attack and the change over the previous 24 hours, then shows whether pressure drops line up with your attacks.
Why does MigNo count painkiller days?
Taking pain relievers on 10 or more days a month can keep a headache going (medication overuse headache). MigNo counts those days so you can discuss them with your doctor. It is a counter, not a diagnosis.
Is MigNo a medical device?
No. MigNo helps you keep a diary. It does not diagnose and does not recommend treatment. Bring your records to a doctor.
Is there an Android version?
Not yet. MigNo is available for iPhone.
