Open Window
Weather decisions and alerts
Free · In-App Purchases
Open Window turns a forecast into clear decisions for your day.
See what to wear, whether to take an umbrella, when opening a window makes sense, and how comfortable it may feel outside. The home view keeps the current weather and key signals for temperature, air quality, wind, humidity, rain, and UV easy to scan.
Start with three days of the standard 3 a.m. and 4 p.m. summaries, important weather-change alerts for your current place, and a basic widget. When the preview ends, the core current-weather home remains available. Open Window Plus keeps alerts and widgets active and adds custom summary times, quiet hours, saved-place alerts, up to four saved places, detailed hourly views, up to 10 days of forecasts including today, richer multi-place widgets, and an option to skip repetitive default summaries when the weather is materially similar.
Choose Current Location for travel-aware weather, or save and arrange the places you care about. Tap a place alert or widget to open that place directly.
No account is required. Weather comes from Apple Weather. Air-quality details may be supplemented by the Open Window server where available. Location is used only for app functionality and optional alerts, not for tracking.
