Window Season vs OpenWindow

Know when to open your windows. Window Season is a tool for helping decide when to open your windows for passive cooling. It watches the temperature, air quality, and rain for the places you care about and gives you one clear call: open up, or keep them closed. Set your comfort range once and it tracks the rest, hour by hour. • Open now or closed now, at a glance • What's next, like "Close at 8 PM" • Whether you should open overnight • Air quality and rain handled automatically • Adjustable comfort settings • Home & Lock Screen widgets on iOS • Apple Watch app, complications, and widgets

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.
