## What is Oh My Headache?

Oh My Headache brings pressure changes, weather, and your symptom records together. It shows four-level headache-risk guidance from available pressure data and lets you record pain and medication.

KEY FEATURES

• Pressure-based risk guidance
Classifies the latest valid pressure drop as a six-hour equivalent. This is general reference information, not a diagnosis.

• Dedicated pressure graph
Distinguishes up to 72 hours of available past pressure data from up to 7 days of hourly forecasts for the selected location.

• 3-day weather
See daily weather, high and low temperature, maximum precipitation probability, and hourly weather, temperature, precipitation probability, and pressure.

• Pollen, modelled air quality, and UV
In Japan, view observed total pollen and a 10-type seasonal calendar. PM2.5 and dust particles are model estimates. UV includes current, today, and tomorrow hourly forecasts.

• Pain diary and notifications
Record pain, medication, and notes, review them on a calendar, and choose pressure or weather notifications.

• Plans
Core features are free. The free plan displays ads and limits some notification choices; the paid plan removes ads and adds notification settings.

DATA SOURCES
Current and past pressure in Japan uses JMA AMeDAS observations. Hourly and future weather and pressure, overseas weather, and UV use coordinate-based Open-Meteo data (CC BY 4.0), processed for display. PM2.5 and dust particles use CAMS ENSEMBLE model data via Open-Meteo. Pollen observations in Japan use Weathernews Open Data. Availability and forecast accuracy vary by location and provider.

IMPORTANT
This app is not a medical device and does not provide diagnosis, treatment, or medical advice. Seek professional care for severe or concerning symptoms.
