Per-window advice
Uses weather and each window’s orientation to suggest actions such as close, crack open, open wide, or place a fan.
Ventilate
Ventilate is a weather-aware home ventilation app for hot weather and heatwaves. It helps people without air conditioning decide when to open windows, when to close them, and when to use fans based on the current forecast and the layout of the home.
Overview
Ventilate is a weather-aware home ventilation app for hot weather and heatwaves. It helps people without air conditioning decide when to open windows, when to close them, and when to use fans, based on the current forecast and the layout of the home.
The product centers on practical, per-window advice. Its guidance reflects whether a home has cross-ventilation or a single-sided layout, which direction the windows face, and whether outside air is actually cooler than indoor air. The site also says the app works on the device, requires no account, and uses WeatherKit for weather only.
What Ventilate does
Home-specific setup
Takes a building profile into account, including whether the home has cross-ventilation or a single-sided layout and what fans are available.
Weather and transitions
Shows local forecasts and the next recommended action so the advice is tied to changing conditions, not just general heat guidance.
Window timing guidance
Supports timing decisions for heatwaves, including when to keep heat out during the day and when to flush warm air after dark.
On-device data handling
Keeps the workflow on the device with no account, and stores home data locally.
Where Ventilate is useful
Managing a hot flat or house
A homeowner or renter without air conditioning can use Ventilate to decide whether to open, close, or fan each window as temperatures change through the day.
Cross-ventilated homes
In a home with windows on opposite sides, the app’s guidance helps identify when a cross-breeze is possible and when to flush out stored heat more aggressively.
Single-aspect apartments
In a single-sided apartment, Ventilate helps narrow down when window opening will actually help and when fan placement matters more than opening everything.
Heatwave timing decisions
During a heatwave, the app supports the routine of keeping heat out in the daytime and ventilating at the cooler transitions after sunset or overnight.
Window and shade planning
When sun on the glass is driving indoor heat, the product’s guidance reinforces that shading and window timing are part of the same cooling strategy.

- Keeps home data local on the device and does not require an account.
- Covers practical heatwave decisions that fit a no-air-conditioning household.
Cons

- The product appears focused on individual homes, and the provided pages do not mention shared or team workflows.
FAQ
How does Ventilate decide what to tell me to do with my windows?
Ventilate applies your home’s window layout, window directions, and current weather to suggest whether you should open, close, crack open, or open wide. The guides also explain the reasoning behind each action so the advice is tied to outdoor temperature, sun exposure, and airflow.
Does Ventilate store my home data in the cloud?
The site says Ventilate has no account and keeps your home data on your device. It also says WeatherKit is used for weather only.
Is Ventilate free or paid?
The homepage says Ventilate is available on the App Store and Google Play, and the guides repeat those download links. The public pages provided do not show pricing details or plan tiers.
What kind of problem is Ventilate meant to solve?
Ventilate is designed for homes without air conditioning, especially during hot weather and heatwaves. The guides focus on when to ventilate, how to shade windows, and where to place fans so they help rather than just move hot air around.
Can multiple people use the same Ventilate setup?
The guides present Ventilate as a consumer app for individual homes, not as a multi-user team product. The source material does not describe collaboration features or shared household accounts.
