I just tried this out on my iPad, and it works great! This is exactly what I was hoping to see as far as widgets go: something that looks almost like an Apple Watch face. Of course, being designed for iPhone, the scaling of the app itself is way off, but you can still select the faces and the widget does indeed work properly. Ignore the one star reviews here; those people are just complaining about the buggy-ness of iOS 14. Apple will get those bugs fixed soon; just wait.
