Apple's software updates previewed during WWDC 2026 this week have followed a distinct pattern: introduce a handful of key new features, while maintaining a focus on refining the underlying platform architecture. watchOS 27 is no different in this respect, with the majority of changes being performance improvements under the hood.
That said, one of the most obvious user-facing changes is a new dynamic app grid that surfaces and rearranges five apps based on your current context and general usage, with Siri as the centerpiece. Pressing the Digital Crown on your Apple Watch immediately invokes the grid, which appears whether you use the app grid or list view. If the dynamic grid doesn't surface the app you're looking for, a turn of the Digital Crown reveals your preferred view.
The change straddles the line between redesigned navigation and the efficiency-minded development that defines the rest of watchOS 27, since the grid aims to get you to the app you want, just faster. It's probably the most obvious change you'll actually see, but there are several others that happen out of sight. Apple says they include:
Improved Wi-Fi connectivity
More efficient water detection
More accurate step tracking
Faster media playback
Faster app extension launchesAs with the rest of Apple's software previews this week, though, you'll need reasonably recent hardware to see any of these enhancements.
watchOS 27 requires an iPhone 11 or later or iPhone SE (2nd generation or later) with iOS 27. The new software also requires one of the following Apple Watch models: Apple Watch SE 3, Apple Watch Series 9, 10, 11, and Apple Watch Ultra 2 or 3. In other words, watchOS 27 drops support for the Apple Watch Series 6, Series 7, and Series 8, along with the original Ultra and SE 2. Apple will release the new software in the fall.
