Apple’s software updates previewed at WWDC 2026 this week followed a distinct pattern: introducing a handful of key new features, while remaining focused on refining the underlying platform architecture. watchOS 27 is no different in this regard, with the majority of changes being under-the-hood performance improvements.
That said, one of the most obvious changes to the user is a new dynamic app grid that presents 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’re using the apps grid or list view. If the dynamic grid doesn’t bring up 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-driven development that defines the rest of watchOS 27, since the Grid aims to get you to the app you want, just faster. This is probably the most obvious change you’ll see, but there are several others happening out of sight. Apple says they include:
- Better battery efficiency
- Improved Wi-Fi connectivity
- More efficient water detection
- More accurate step tracking
- Faster media playback
- Faster app extension launches
As with the rest of Apple’s software previews this week, you’ll need reasonably recent hardware to see any of these improvements.
watchOS 27 requires an iPhone 11 or later or an 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, as well than the original Ultra and SE 2. Apple will release the new software in the fall.
