After launching the app and not doing anything else—no scrolling or clicking—the Windows 11 Weather app consumed over 1.2 GB of RAM.
Compare that to the ad-free macOS Weather app.
As mentioned, the Windows 11 Weather app takes up a lot of RAM.
This is how much RAM the macOS Weather app uses, according to the Activity Monitor.
The Windows 11 Weather app therefore uses at least five times as much RAM as the macOS app does.
