Overview
- Apple previewed watchOS 27 at WWDC and released a developer beta with a public beta expected in July and a broad fall release planned.
- A new dynamic app grid appears when you press the Digital Crown and surfaces five contextually relevant apps with Siri placed at the center.
- watchOS 27 adds a dedicated Siri app that stores cross‑device conversations and a unified Find My app that merges Find Devices, Find Items, and Find People.
- Most visible changes are performance and stability fixes that Apple lists as better battery efficiency, improved Wi‑Fi, more efficient water detection, more accurate step tracking, faster media playback, and quicker app extension launches.
- The update requires an iPhone 11 or later and supports only SE 3, Series 9–11, and Ultra 2–3, which drops Series 6–8, Ultra (1st gen), and SE 2 and signals a shorter Apple Watch software support window tied to newer silicon.
