A vocal number of heavy-duty iPad users have begged for mouse support on the iPad for years, and that support finally exists on iPadOS 13. A little surprisingly, iOS 13 also brings mouse support to the iPhone.
It’s not so surprising, though, that Apple chose to bury it deep within the iPhone and iPad’s Accessibility settings. And when you do hook up a mouse through a Bluetooth or wired connection, you’ll still have to deal with an ugly circular cursor that’s meant to mimic a human fingerprint and a few interface complications. We’re glad the feature’s here, but it doesn’t quite work the way we’d hoped. (It is, after all, designed as an Accessibility feature called "AssistiveTouch.")
