Apple unveils watchOS 27 with performance upgrades and a dynamic app grid
At WWDC 2026, Apple announced watchOS 27, highlighting a new context-aware app grid and a series of under-the-hood performance enhancements, while dropping support for older watch models.
Apple introduced watchOS 27 at its WWDC 2026 event, emphasizing a blend of modest new features and extensive platform refinements. The most visible addition is a dynamic app grid that automatically surfaces five frequently used apps based on the user's current context, with Siri positioned at the center. Users can access the grid instantly by pressing the Digital Crown, and rotating the crown switches between the dynamic view and the preferred layout.
Beyond the visual change, Apple listed several background improvements, including better battery efficiency, enhanced Wi-Fi connectivity, more efficient water detection, more accurate step tracking, faster media playback, and quicker app extension launches. These enhancements require recent hardware; watchOS 27 is compatible with iPhone 11 or later (or iPhone SE 2nd generation and later) running iOS 27, and with Apple Watch SE 3, Series 9, 10, 11, and Ultra 2 or 3. Support for Series 6, 7, 8, the original Ultra and SE 2 has been discontinued. The update is slated for release in the fall.
