OpenWindow vs Open Window

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.
