Window Watcher for iOS

Combine the power of Apple Weather with your own HomeKit temperature sensors to know exactly when it’s time to open or close your windows.

Set custom temperature values to bring Live Activities like shown above right to your Lock Screen when forecasts indicate it’s time. Check your own sensors to know when the weather forecast isn’t matching your microclimate.

Display your HomeKit sensors in colorful widgets that let you monitor temperatures and humidity inside, outside and compare across your home.
