Plan natural ventilation around your home and local weather

Ventilate helps people decide when to open or close windows and how to position a fan as conditions change. The app combines local weather with details about a home's layout, window directions, indoor temperature, sun exposure, and available fans. Its recommendations distinguish between rooms and windows instead of giving one instruction for the whole home.
Users can see the next suggested action and receive reminders when a useful ventilation window approaches. Weather conditions such as rain, pollen, or a hot night can change the advice. Companion guides explain airflow, shading, and other practical ways to manage indoor comfort without relying entirely on air conditioning.
