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
