Kephale

Your migraine diary. Simple when it hurts.

One tap logs an attack. See your month at a glance, bring your doctor a report. All on your iPhone.

Coming soon to the App StoreSee a sample report
Calendar: each day is a ring, longer arcs for worse pain
Reports: the triggers, symptoms and reliefs that come up most often around attacks
Summary screen: days without an attack, the latest attack, and this month in numbers

Built for the worst moment

When your head hurts, the app asks for one tap. The details can wait.

Intensity card: 6 points, moderate

Pain from 1 to 10

One slider. It shapes your summary and the report for your doctor.

  • Start attack button

    One tap to start

    Start an attack from the app, the Lock Screen, Control Center or your Apple Watch. Add the details later, or skip them.

  • Medications card: Ibuprofen marked helped, Sumatriptan waiting for “Did it work?”

    Doses, and whether they helped

    Record a dose in a tap. Later, the app asks whether it worked.

  • Head map: left temple marked

    Where it hurts, on a head map

    Tap the side and the spot. Symptoms and aura are one tap each.

  • Duration card: an attack running for 80 hours, with the question whether you forgot to end it

    Forgot to end it? It asks.

    After 12 hours, then after one, two and three days. Four times in all, then it stops.

Your diary in three steps.

  1. The start screen with one large button to start an attack

    Tap when it starts

    From the app, the Lock Screen, Control Center or your Apple Watch. The timer runs while you rest.

  2. Add details when you can

    Where it hurts, symptoms, possible triggers, what you took. Skip any of it. The attack is already saved.

  3. First page of the PDF report

    A PDF with headache days and medication days for each month, in your doctor’s language. Part of Pro.

Calendar

Your month at a glance

Each day is a ring. The longer the arc, the worse the pain. A long attack runs as one band across the days it covered.

October

Sample data

October 18Pain 9 of 10, severe · Medication taken

How to read it

  • Arc length: pain from 1 to 10
  • Mark at the bottom: you took something that day
  • Dotted ring: an attack with no pain level recorded
  • Slight 1-2
  • Mild 3-4
  • Moderate 5-7
  • Severe 8-10
Reports: the triggers, symptoms and reliefs that come up most often around attacks
Pro

Triggers that keep coming up

See which triggers come up most often before your attacks, in any period back to your first entry. The counts show what happens together, not what causes what.

Medications report: how well each medication worked and medication days per month
Pro

Which medications help

Answer “Did it work?” after a dose, and the report shows how well each medication worked. It counts medication days per month (days, not tablets) next to guideline thresholds. Reaching one is not a diagnosis.

Pro

Sleep and cycle, next to your attacks

With your permission, Kephale reads your sleep and period days from Apple Health and sets them beside your attacks. Both stay off until you turn them on. What it reads is never copied into the diary.

Sleep report: how long you slept before attacks compared with other nights
Barometric pressure and weather recorded with an attack

The weather when it started

With weather recording on, each new attack is saved with the barometric pressure, its 24-hour change, temperature and humidity. Your approximate location goes to Apple, not to us, and isn't kept. Weather data by Apple Weather.

ProWeather recording is free. The pressure report across your attacks is part of Pro.

Home Screen widgets: days without an attack and the month

Without opening the app

Start or end an attack and record a dose on Apple Watch. Home and Lock Screen widgets show the time since your last attack. They're marked sensitive, so iOS can hide them on a locked iPhone.

For your doctor

A report with the main answers on page one

First page of the PDF report: headache days and medication days per month

Summary, page 1 of 3

Page one shows headache days and medication days for each month, next to the thresholds headache guidelines use. Triggers, medications and the full attack log follow, in the language you choose. Part of Pro.

Common questions

Can’t find yours? Ask below. We reply by email.

Is Kephale free?

Yes. Logging attacks, the calendar and this month's summary are free for good. Pro adds reports for any period, the PDF for your doctor and color themes.

Where is my diary stored?

On your iPhone, in the app's private storage, protected by your device's encryption. There is no account and no cloud sync. Your device backup includes the diary, as it does for any app.

Does Kephale diagnose migraine?

No. It's a diary. It counts what you record and shows it clearly, so you and your doctor can talk about it.

Does it predict attacks?

No. Kephale shows what you've already recorded. It doesn't forecast anything.

Does it read my Apple Health data?

Only your period days and your sleep. Each has its own switch, and both are off until you turn them on. Nothing else is read.

What happens to my diary if Pro ends?

Nothing is deleted. Your records, the calendar and this month's summary stay. The app goes back to its standard look, and if you renew, your theme comes back.
