Apple has released watchOS 27, featuring Siri AI, enhanced fitness tools, and a revamped Apple Watch interface.

      Apple has officially introduced watchOS 27 at WWDC 2026, marking one of the most significant updates for the Apple Watch. This new software brings Siri AI, enhanced Apple Intelligence features, advanced fitness tools, and a revamped user interface aimed at increasing the smartwatch’s daily utility.

      This update aligns with Apple’s greater initiative to integrate Apple Intelligence across its platform. While the Apple Watch has traditionally emphasized health and fitness, watchOS 27 seeks to make the device more proactive, contextual, and adept at managing everyday tasks directly from the wrist.

      A key highlight of this update is Siri AI, an AI-driven assistant experience specifically for the Apple Watch. Users can engage with Siri using natural language, ask follow-up questions, and execute tasks across applications more effectively. Siri AI, leveraging Apple Intelligence, is designed to better comprehend context, making interactions feel more conversational than in the past.

      Siri AI and Apple Intelligence take the spotlight

      Apple is also enhancing Apple Intelligence features on the Apple Watch. Siri can now offer more contextual support, while smart suggestions throughout the system aim to present pertinent information when users need it most.

      The Smart Stack has been improved with better predictive algorithms that recommend helpful actions and widgets based on users' daily routines. Messages also receive additional intelligent features, such as Live Translation and smart action suggestions that aid users in responding to messages quickly or sharing information like their location.

      Fitness continues to be a key emphasis in watchOS 27. The Workout Buddy feature returns with more personalized coaching and motivation powered by Apple Intelligence. The Workout app has been redesigned for easier access to frequently used features, while Apple Music can now automatically suggest playlists tailored to workout types and listening habits.

      Additionally, Apple has introduced features like automatic volume adjustment based on external noise, enhanced notification management, and improvements to the Notes app, which is now accessible directly on the Apple Watch.

      Which Apple Watches will receive watchOS 27?

      One of the major changes this year is compatibility. Apple has significantly limited support for older Apple Watch models. Reports indicate that watchOS 27 will be available for newer Apple Watch hardware, including recent Series models, Ultra models, and the latest SE variants, while several older generations will not be supported. Apple later specified that compatibility includes the Apple Watch Series 9 and newer devices.

      The developer beta is currently available, with the public beta expected to launch in July. Apple plans to release the final version of watchOS 27 later this fall alongside its wider software rollout.

      With the introduction of Siri AI, deeper integration of Apple Intelligence, and new health and productivity features, watchOS 27 marks Apple’s most ambitious effort yet to evolve the Apple Watch from simply a fitness companion into a more versatile everyday assistant.
