## What is KaradaTenki?

"That headache? It might be the weather." KaradaTenki is a barometric-pressure forecast and symptom diary for weather-sensitive people — built for Japan's 天気痛 (weather-pain) sufferers, useful anywhere pressure swings hurt.

PRESSURE FORECAST
• 7 days of barometric pressure with a four-level alert scale (Stable → Warning)
• "Sharpest drop around 12:00" — see when the fall bottoms out
• 48-hour pressure curve, prefecture picker, no location permission

PRESSURE-DROP ALERTS
• A local notification about 2 hours before a sharp fall — time for medicine, water and a plan
• No push server, no account

30-SECOND DAILY CHECK-IN
• Headache level, symptom chips, medicine — logged in a few taps
• Edit today from the home screen; edit any past day too
• A daily reminder builds the habit

YOUR HEADACHE × PRESSURE PATTERN
• Average headache per forecast level, from your own records — prove the connection
• Symptom frequency and medicine-day counts to bring to your doctor
• Everything stays on your phone. No ads, no account

The forecast, your last 10 days and headline stats are free forever. Premium unlocks unlimited history and every advanced stat.

Note: this app records and informs; it is not a substitute for medical diagnosis or treatment.
