Do you have a clear understanding of when, how, and how severe your daily headaches are?

"Headache Log" is a simple and easy-to-use health management app designed for people suffering from migraines and tension headaches.

Even when you're suffering from a painful headache, simply open the app and record your pain with just a few taps. Use the calendar and graphs to analyze your pain trends (in relation to weather and barometric pressure) and use the information to help you manage your headaches!

【✨ Main Features of Headache Log ✨ 】

✅ Super-Simple Input Screen
Just choose from four levels: "Severe Pain," "Throbbing," "Slight Pain," and "No Pain"! You can also quickly record the weather that tends to cause headaches, the medications you've taken, and any notes you've noticed. You can also record past dates and times.

✅ See the ups and downs of your physical condition at a glance with the calendar.

For days you've logged, a dot of a color corresponding to your pain level will appear on the calendar. Just by looking at the calendar, you can quickly see how often you've had headaches this month and when your days were good.

✅ List View and Sorting
You can review your past records by sorting them by "Newest," "Oldest," or "Pain Severity."

✅ Reliable Privacy Design (Offline Support)
All entered data is stored exclusively on your smartphone. It is never sent to external servers, so you can safely record your personal health data.
