Indeed, Liquid Glass does bring somewhat of a major change to iOS 26, or what we would have called iOS 18 (Apple is switching iOS numbers to years, and iOS 26 will release in the fall). I've been using the developer beta of iOS 26 for some weeks now,

WatchOS 26 brings the Liquid Glass look, helpful Smart Stack hints, and easier Workout app customizations to your Apple Watch. I took the beta for a spin, and here's what I'm liking.

Certainly one of the main highlights of iOS 26, which was announced earlier this month at WWDC 2025, is the new Liquid Glass interface. But as we’ve reported here, the update also comes with a lot of other new features – such as many new APIs that open up a lot of possibilities for app developers.
