## What is 頭痛予報?

Please note: this app is available in Japanese only.

頭痛予報 (Headache Forecast) helps people who get headaches when the weather changes. See when the air pressure is about to drop, and keep a simple record of your headaches to share with your doctor.

■ Full-screen air pressure graph
See the air pressure in your area hour by hour, with weather, temperature, sunrise and sunset. Times when the pressure changes sharply within 3 hours are marked "注意" (caution) or "警戒" (warning).

■ Weather forecast and typhoon alerts
24-hour weather with short comments, a 7-day forecast with rain chance, wind and humidity, and alerts when a typhoon is forming or approaching (based on Japan Meteorological Agency data).

■ Easy headache log
Tap to record how strong the pain is and which medicine you took. You can also note your period, period pain, other symptoms and memos. The time and air pressure are saved automatically.

■ Calendar and report for your doctor
See headache days, medicine, period and pressure changes on a calendar with Japanese holidays. Summarize 1, 3 or 6 months of headache days, medicine use, period cycle and the link to air pressure, and share it.

■ Private
- No ads
- No account or login needed
- Your records are stored only on your phone
- Only approximate location (about 1 km) is used to get air pressure
