WWDC 2025 keynote.
Each of the three operating system upgrades features the refreshed Liquid Glass design. While this updated interface is more prominent on iOS 26, iPadOS 26, and macOS 26, Apple continues to refine the UI in these additional software iterations, including watchOS 26 beta 4, which now presents a bubbly Passcode screen.
Apple has also improved the Smart Stack in watchOS 26 beta 4. When you visit the gym, a workout recommendation will show up, and even if you lose cellular signal, the Apple Watch can guide you back. A new wrist flick feature for Apple Watch Series 9 and later devices now makes it simpler to clear a notification.
