My own experience, is that I keep on not using it in my projects. It's too much of an "in your face" widget. I was going to do a SwiftUI version of it, but stopped working on it, when I figured out that I probably wouldn't use it.
I suspect that MacOS, with the cursor-oriented navigation, is a better home for it.
I wrote a Swift package that does a similar thing (but as an iOS widget): https://github.com/RiftValleySoftware/RVS_Spinner
