OpenWindow vs OpenAir

OpenWindow helps you decide when the air outside is worth letting in. Check whether it is a good time to open your windows or go outside using local weather and air-quality conditions. OpenWindow combines temperature, humidity, precipitation, wind, visibility, UV, and air-quality data into clear, practical recommendations. Instead of making you interpret every weather metric yourself, OpenWindow gives you simple guidance for two everyday questions: - Is it a good time to open the windows? - Is it a good time to go outside? Features: - Current recommendations for windows and outdoor activity - Hourly outlooks so you can plan around better conditions - Weather and air-quality data powered by Open-Meteo - Current-location lookup with optional location permission - Manual location search if you prefer not to use device location - Saved default location for quick checks - Unit preferences for temperature, wind, visibility, and more - Light and dark mode support - No account required OpenWindow is built for quick, low-friction decisions: checking the room before opening a window, planning a walk, timing errands, or seeing whether air quality makes staying inside the better call. Location access is optional and used only to fetch local weather and air-quality data. You can always search for a location manually instead.

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.
