OpenAir: Window Weather
Know when to open windows
Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.
OpenAir helps you decide when to open or close your windows using outdoor weather and your comfort settings.
It checks outdoor temperature, dew point, rain, and wind, then gives you a clear recommendation. Explore up to 10 days of hourly temperature and dew point charts, with your comfort limits and window guidance shown alongside them.
Use OpenAir to:
* See a simple open or close recommendation
* Find upcoming periods when outdoor conditions suit your preferences
* Check temperature and dew point trends before opening your windows
* Avoid rain, strong wind, and humid outdoor air
* Get alerts when the recommendation changes
* Check your status with iPhone widgets and Apple Watch
Set your preferred outdoor temperature range, maximum dew point, and wind limits to tailor the guidance.
OpenAir uses outdoor conditions only. It does not measure indoor temperature, indoor humidity, or air quality. Alerts and background updates are best-effort and may be delayed by iOS.
