Captain: Migraine Logbook

A migraine diary for the moment the screen itself hurts.

One tap to log an attack. Say the rest in your own words, later.

Public TestFlight link is coming. Until then, write to us and we will send an invite.

iPhone, iOS 18 or later. Free. No account.

Captain home screen in the evening: today marked as a clear day, 12 of 30 days towards 10 more voice entries, factor chips, and two big buttons - Speak it and Log it - on a dark amber background.

Say it, don't type it

Tell it in your own words, by voice or by typing. AI turns it into an entry - time, intensity, pain, medicine, triggers. You check it before saving. Your words are not stored.

The voice screen with the story as it was told: arguing with the navigator in the morning, no coffee, a strong headache with a throbbing left temple by noon, loud whales, ibuprofen, gone by evening. Below it, what was recognized: today from noon to 7 PM, pain 8 of 10, pulsating, temple, left side, head pain, fatigue. — You said it. The entry filled itself in.

The attack entry filled in from that story: intensity 8 of 10, left side, pulsating and temple pain, head pain, sound sensitivity and fatigue, ibuprofen 400. — You said it. The entry filled itself in.

In the moment

One tap logs the start of an attack. The rest can wait. Dark, low-glare screens with three calm themes: no white, no flashing, no required fields.

Afterwards

Calendar for September: green dots on clear days, amber dots on attack days, short marks under days with factors. Today is selected and shows its attack and factors. — Clear days in green, attacks and factors at a glance.

An attack entry: ibuprofen 400 at 1 PM with the answer Gone after two hours, and the factors - emotional upset, caffeine withdrawal, loud noise, crowded place. — Every attack in one place: what you took, did it help, what set it off.

Two hours after a medicine, a quiet question: did it help?
Days with acute medication this month, next to commonly cited thresholds - something to discuss with your doctor, not a verdict.
Month numbers: attacks, days with medication, average intensity and duration.
Export everything as CSV or JSON.

What is free

The diary is free and stays free: unlimited entries, history, calendar, themes, export. Voice entry comes with 10 entries to start, 5 more every month and 10 more for every 30 days logged in a row. Unused entries carry over.

A paid tier may come later for unlimited voice and reports for your doctor. Nothing that is free today will become paid.

Who it is for

People with migraine who want to keep a record but give up on diaries that ask for twenty fields while the head is splitting. If you have tried other apps and stopped, this one was built around that exact moment.

From the maker

I have migraine with light sensitivity. Every diary I tried wanted a form filled in while I could barely look at the phone, so I stopped using them and lost the history my neurologist asked for. Captain is what I wanted instead: one tap now, details later, and a screen that does not hurt. I use it every day. During the beta I read every message.

Questions

Is this medical advice?

No. Captain does not diagnose, treat or predict anything. It keeps an honest record and helps you notice patterns in your own data. Please discuss what you find with a healthcare professional.

Does my data leave my phone?

Your diary stays on your iPhone. The only exception is a voice note: it is sent once to an AI service to fill in the entry and is not stored. Our server keeps only a short technical note - that a request happened, whether it worked, how long it took and how many items were recognized - without anything you said, for up to two years. There is no account and no analytics of your health data.

What happens if I stop paying later?

The diary, your history and export do not depend on any subscription. Voice goes back to the free entries: your balance stays and keeps growing every month.

Android?

Not yet. iPhone first.
