"I can't keep track of my headaches," "I can't understand my headache patterns"—for those people, this app helps you record and visualize your headaches, helping you to cope with painful headaches more effectively.

【Three Features of Headache Notebook】
1. Simple and Quick Recording
When you're suffering from a headache, you don't want to struggle with long input forms, right?

With Headache Notebook, you can quickly record the intensity, location, and type of pain with a tap. Just enter the necessary information.

You can also record the name and dosage of medications taken, whether they were effective, triggers, and accompanying symptoms.

Furthermore, by registering frequently entered patterns in "My Sets," you can complete entries with a single tap next time.

We've prepared a system to help you continue recording even when your headaches are severe.

2. Easy-to-View Data
Recording is meaningless if it's just accumulated. It only becomes valuable when you review it.

- Calendar View: Easily grasp the occurrence of headaches at a glance with color coding. "I had a lot of headaches this month," "I felt good this week," etc. are immediately apparent.
- Medication Calendar: Visualizes the number of days medication was taken in the last 30 days. Useful for reviewing medication status.
- Summary Report: Check changes in headache frequency, average intensity, and duration by day and period.
- Ranking: Displays triggers, symptoms, and medications in order of frequency or effectiveness. "What's most common for me" and "Self-assessment of effectiveness" are immediately clear.

Understanding headache trends and effective countermeasures makes it easier to decide "what to do next."

3. AI Analysis
Based on recorded data, AI summarizes headache trends in a report. (Premium feature)

You can choose periods such as 14, 30, or 90 days, allowing you to objectively understand both "recent changes" and "long-term trends." AI supports data summarization and review, helping you discover patterns you might not notice yourself.

[Other Useful Features]
1. Weather and Barometric Pressure Linkage
For those who feel unwell on low-pressure days, weather and barometric pressure changes are displayed. You can use barometric pressure conditions as a guide.

2. Notifications and Reminders
- Recording Reminder: You can answer whether you have a headache today with one tap. This prevents you from forgetting to record.
- Barometric Pressure Change Notification: You will be notified when a large change in barometric pressure is forecast. This can be used as a guide for adjusting your schedule and managing your health.

[How to Use]
1. When a headache occurs → Open the app and quickly record.
2. At the end of the month or on weekends → Review using the calendar or report.

[About Data Management]
- Recorded data is saved to the cloud. You can transfer your data even when changing devices by logging in with your account.
- When generating AI reports, recorded data is sent only for analysis purposes. This information will not be used to train the AI ​​model.
- Please do not enter personally identifiable information (such as name, address, or phone number) in your records.
- You can check our Privacy Policy at any time within the app.

[Caution]
This app is a tool to help you record and review headaches and does not provide medical services (diagnosis, treatment, or prescription). All content, including AI reports, is not a medical diagnosis but reference information based on recorded data. If you have concerns about your health or if your symptoms persist, please consult a medical institution.

Recording your headaches will transform them from "vaguely bothersome" to "seeing patterns." Try starting by recording your next headache.
