## What is Lun?

Lun is a migraine diary built around one simple truth: you cannot fill in a form while a migraine is happening. So one long press is all it takes to log an attack. The details can always wait until you are ready.

Over time, Lun gathers your log into patterns you can actually use: when attacks come, how strong they are, what keeps recurring, and how sleep, cycle and air pressure play in.

HOW YOU USE IT
Hold the breathing circle on the home screen when an attack begins. The time is saved at once. Add intensity, symptoms and triggers once you are back on your feet, or leave it.

WHAT YOU GET
Log attacks with one press, unlimited. History and a calm calendar. Core patterns and triggers. When in the week and the day attacks come, and how strong. Reminders and an overview of your medicines.

WITH LUN+
How air pressure, sleep and cycle connect to your attacks. A heads up if you near the point where acute medication, taken too often, can itself cause headaches. A tidy report you can bring to your doctor.

PRIVACY IS THE WHOLE POINT
Everything you log stays on your device, and syncs only through your own private iCloud. No server, no ads, no tracking. The only thing that leaves your device is a coarse, rounded location when you want to see air pressure, and it never contains health data.

Lun does not diagnose. It shows patterns and points you to a doctor when needed. Lun is the first health app from Haug & Datter.
