About Window Opened Dates
Window Opened Dates helps you remember when each room was last aired.
In winter, it is easy to forget bedrooms, closets, north-facing rooms, laundry areas, and corners behind furniture. This simple tracker shows the last window-opening date for every room, how many days have passed, and which rooms may need fresh air today.
Features:
- Track the last ventilation date for each room
- One-tap "opened today" records
- Winter check mode for forgotten rooms
- Room notes for condensation-prone spots
- Local reminders
- JSON, CSV, and ZIP export/import
- Phone and tablet support
- No ads, no analytics
