頭痛ノート｜記録・服薬・誘因を分析

Headache Notebook is an app that visualizes and records recurring headaches, such as migraines and tension headaches.
Simply tap to record the intensity, medication taken, and any suspected triggers the moment the pain starts. The more you use it, the clearer your headache patterns will become.

■ Features of this app: Records monitor for medication overuse headache
Using painkillers or triptans for many days each month can lead to "medication overuse headache (MOH)," where headaches become chronic.
Headache Notebook follows the International Classification of Headache Disorders (ICHD-3) and the guidelines of the Japanese Headache Society, automatically counting the recommended number of days of use:
* Triptans and combination analgesics: 10 days per month
* Simple analgesics (Loxonin, Calonal, etc.): 15 days per month
As you approach the standard, the medication usage gauge on the home screen changes color (green → yellow → red).
It doesn't just "record," but helps you notice early signs of overuse. This is what sets it apart from other headache apps.
(*Preventive medications and anti-nausea medications are not counted towards the number of days taken. This is a guideline for when to see a doctor, not a diagnosis.)

■ Recording is easy. The moment the pain starts:
- Select one tap for intensity (mild/medium/severe/unbearable)
- Simply choose medication from a list, from over-the-counter to prescription drugs. You can also record whether it "worked/didn't work".
- Tap on triggers (low pressure, menstruation, lack of sleep, stiff shoulders, hunger, stress, etc.) and accompanying symptoms.
- You can choose the time from "Now/30 minutes ago/1 hour ago..." so you can accurately record it later.

■ The more you continue, the better you understand: Analysis of your headaches
- Ranking of most common triggers (how effective low pressure and lack of sleep are)
- Effectiveness of each medication (don't keep carrying around medications that don't work)
- Monthly frequency trends and monthly medication days (see months with excessive medication at a glance)
- You can also manually tap and record atmospheric pressure and weather (low pressure, changes in atmospheric pressure, etc.) as triggers for review.

■ Take it directly to your doctor's appointment.
- Consultations are short. Showing a record is faster and more accurate than explaining verbally.
The headache notebook automatically creates a "summary to show your doctor" that summarizes the most recent headache days, medication days, most common triggers, and medication effectiveness.
You can also export the data as a CSV file (a table that can be opened in Excel).

■ Privacy: Headache records are stored only on your device
All headache records (severity, medication, triggers, notes, etc.) are stored only on your smartphone and are not sent to a server. No account registration is required, and location information is not collected.
