Apple released watchOS 27 beta 3 today, finally delivering the upgraded Siri AI experience and a standalone Siri app to Apple Watch after announcing both at WWDC in June. The first two developer betas omitted these features entirely, leaving developers waiting for the promised AI overhaul.

The new dynamic app grid now positions the Siri app as the center option, with surrounding icons intelligently selected by the system. The Siri app syncs across iPhone, iPad, Mac, and Apple Vision Pro, letting users continue conversations with full context between devices — a first for Apple's wearable.

Updated watches may need time for the Siri experience to fully load before AI features become available. This brings a ChatGPT-like conversational assistant to the wrist, positioning Apple Watch as a more capable AI wearable.

The delayed arrival in beta 3 suggests Apple needed extra optimization for the Watch's constrained hardware. Cross-device sync could make Siri genuinely useful for multi-device owners, but real-world latency, battery impact, and offline capability remain untested until public release.
