Don’t let pressure changes throw you off.
Hectopas is a minimal atmospheric-pressure app that gently alerts you to sharp pressure changes.
If headaches, fatigue, or other pressure-related symptoms affect your day, it helps you plan with a simple, clear screen.
■ Who it’s for
・People whose condition often shifts with pressure
・Those who want to focus on pressure changes, not just the weather forecast
・Fans of clean apps without clutter
・Anyone who wants a quick pressure outlook before going out or starting work
■ Alert levels at a glance
The Home screen shows today’s pressure status in three levels:
・STABLE (Normal) — No major changes expected
・CAUTION (Caution) — Watch for pressure changes
・ALERT (Warning) — A sharp change is expected
Thresholds are set a bit early for pressure-sensitive people. Both rises and drops are covered.
■ Free forecasts from today through one week ahead
・Today’s pressure chart (0–24h)
・24-hour outlook text
・One-week pressure forecast (daily and weekly)
■ Alerts before the change
Get a push notification before a large pressure shift.
Caution and Alert level changes are announced 1 hour ahead by default—so you can prepare before symptoms appear.
■ Home Screen widgets
Small and Medium widgets are free. Check today’s alert level and pressure outlook without opening the app.
Note: Due to widget limitations, data may not always be up to date. Opening the app refreshes it.
■ Minimal, comfortable design
A clean layout with Light, Dark, and system-linked themes.
■ Choose a prefecture for your local pressure
Select your region from prefectures across Japan to display local pressure data.
■ Premium (optional)
Core features stay free. Premium is available if you want a more comfortable experience:
・Morning briefing (today’s alert level and outlook)
・Finer alert timing (30 min / 1 hour / 2 hours ahead)
・Separate ON/OFF for Caution and Alert
・Widget display options
・Custom color styles and accent colors
・Hide banner ads
Choose monthly, yearly, or lifetime.
■ About the data
Pressure data comes from weather forecast pressure information.
Alerts are guidance based on forecasts—not medical advice or diagnosis.
If you have health concerns, please consult a medical professional.
■ Requirements
iOS 16.0 or later
Know the pressure shifts. Feel better each day.
Hectopas supports your day.
