iPhone & Apple Watch · free to start
One tap, and your attack is logged.
Kopfwolke adds barometric pressure and weather for you, so your headache calendar is ready for your next doctor’s appointment.
Logging, the calendar and your full history are free. No account, no ads.


What Kopfwolke does
Log in seconds
Start an attack in the app, from a widget, Control Center or Apple Watch. Intensity, symptoms and medication are optional – add details later, when you feel better.
Pressure and weather, automatically
Barometric pressure, temperature and humidity for every day, no typing. Sleep and cycle from Apple Health, if you allow it.
Let family or work know
After you start an attack, Kopfwolke offers your prepared messages. You see each one first and tap Send yourself. The template for work does not mention a diagnosis.
Ready for the doctor
Your calendar shows headache days at a glance. With Pro, a two-page monthly PDF lists headache days, severe days and medication days per drug class.
Kopfwolke Pro
Pressure heads-up the day before a forecast drop, a timeline with pressure, sleep and cycle next to your attacks, the doctor PDF and a pressure forecast in the widget.
Private by design
No account, no server, no ads, no tracking. Your health data stays on your iPhone and never goes to the cloud. CSV export is always free.

Frequently asked questions
- Is Kopfwolke free?
- Logging, the calendar, your full history, CSV export, Apple Watch, widgets and notifying are free. Kopfwolke Pro adds the pressure heads-up, the timeline, the doctor PDF and the pressure forecast in the widget: €27.99 a year with a 7-day free trial, €4.99 a month or €59.99 once.
- Where is my data stored?
- Only on your iPhone and, if you use it, your Apple Watch. There is no account, no server and no iCloud sync. For weather, the app sends a location rounded to about 1 km to Apple WeatherKit.
- Where do pressure and weather come from?
- From Apple Weather. Kopfwolke adds barometric pressure, temperature and humidity for your approximate location or a place you choose – you don’t type anything.
- Does Kopfwolke predict migraine attacks?
- No. Kopfwolke is a diary, not a medical device. It shows your entries next to pressure, sleep and cycle but does not evaluate them. The pressure heads-up is weather information, not a warning about an attack.
- Does Kopfwolke send messages automatically?
- No. After you start an attack, Kopfwolke offers your prepared messages, but you see each one first and tap Send yourself. The template for work does not mention a diagnosis.
- Do I need an Apple Watch?
- No. Kopfwolke runs on iPhone with iOS 26 or later. The Apple Watch app is optional and lets you start an attack from your wrist.
Kopfwolke is a diary, not a medical device. It does not diagnose, does not evaluate your entries and does not replace medical advice or treatment. It is not an emergency service.
