OpenWindow: Weather tracker

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.
