Apple has released the public beta of watchOS 27, giving Apple Watch users an early look at the software update scheduled for a full launch this fall. This beta introduces several transformative features, most notably Siri AI integration directly on the wrist, along with refinements in navigation, gestures, health tracking, and system intelligence.

How to Join the watchOS 27 Public Beta

Before installing watchOS 27, users must update their paired iPhone to the iOS 27 public beta. The process is straightforward but requires careful steps:

• Visit the Apple Beta Software Program website and sign in with your Apple Account.
• Accept the program terms and enroll your account if you haven't already.
• Open the Watch app on your paired iPhone.
• Navigate to My Watch > General > Software Update > Beta Updates.
• Select watchOS 27 Public Beta.
• Return to Software Update, then tap Download and Install when the beta appears.

Your Apple Watch must have at least a 50% charge, remain on its charger, and stay near the paired iPhone during the update. The iPhone must also be connected to Wi-Fi. Once the beta is installed, downgrading to an earlier watchOS version is not possible—users must wait for a newer build if issues arise.

Compatibility with watchOS 27 is narrower than previous years. Supported watches include Apple Watch Series 9, Series 10, Series 11, Ultra 2, Ultra 3, and Apple Watch SE 3. The paired iPhone must be an iPhone 11 or newer, or iPhone SE (2nd generation or later), running iOS 27.

Siri AI Comes to the watchOS 27 Public Beta

The most significant addition in watchOS 27 is Siri AI, first introduced in developer beta 3. While the experience is still rough around the edges in the public beta, it represents a major leap forward for Apple Watch as an AI wearable. Siri AI can answer broader questions, understand personal context, and perform actions inside apps—such as locating a door code from an email or adjusting an Activity goal.

The dedicated Siri app syncs conversation history privately through iCloud, allowing users to start a query on an iPhone and continue it on the Apple Watch. Users can also pin important conversations for easy access. To test the feature, try asking a question on the watch that would normally require reaching for an iPhone, then follow up without repeating context. If consistent, watchOS 27 could make the Apple Watch a full-fledged AI assistant. Note that Siri AI requires a compatible watch and a nearby Apple Intelligence-enabled iPhone.

Dynamic App Grid and Smarter Smart Stack

Pressing the Digital Crown now opens a new dynamic app grid. The Siri app remains centered, while recently used and popular apps fill surrounding positions. This adaptive layout makes launching frequently used apps faster and more intuitive.

Smart Stack has become more proactive, surfacing relevant information such as a parked car location or a Siri conversation to continue. Before a holiday, it may remind you to adjust tomorrow's alarm. Location context adds further intelligence—Theater Mode may appear at a concert, while an ID can surface at the airport. These enhancements reduce friction by presenting the right information at the right time.

New One-Handed Tap Gesture

watchOS 27 introduces a one-handed tap gesture that complements the existing double tap feature. The sequence works as follows: double tap scrolls through Smart Stack widgets, a single tap of index finger and thumb selects the highlighted widget, and a wrist flick returns to the watch face. This allows navigation, selection, and dismissal without touching the display, making the watch more usable when the other hand is occupied.

Health and Fitness Upgrades

Three notable health and fitness improvements highlight watchOS 27. First, Workout Buddy now delivers Apple Intelligence coaching without requiring an iPhone nearby. It recognizes longer-term progress in distance, pace, and workout duration, and has added Spanish language support.

Second, new machine-learning algorithms improve treadmill distance measurements from the very first step, making indoor runs more accurate. Step counts in Fitness and Health apps now sync seamlessly.

Third, Cycle Tracking has been enhanced for users aged 40 and older. The feature can notify users when logged patterns may suggest perimenopause, and adds symptom logging and educational resources. These updates demonstrate Apple's continued investment in women's health and proactive wellness monitoring.

Additional Features in watchOS 27 Public Beta

Beyond the headline features, watchOS 27 includes several quality-of-life improvements. A unified Find My app replaces three separate apps, with Precision Finding supporting paired iPhones, second-generation AirTags, and AirPods Pro 3. Wallet can display custom passes created on an iPhone and pin them in Smart Stack. Call Context provides useful information during business calls.

Apple has refined Liquid Glass for stronger contrast and sped up Music playback. The system may also suggest disabling rarely used features—such as gestures, Start Workout reminders, or Raise to Speak—to extend battery life. These can be restored in Settings at any time.

For families, Apple Watch For Your Kids gains redesigned Screen Time controls, app-availability schedules, and approved-contact management. This makes managing multiple watches in a family easier and more secure.

9to5Mac's Take (Rewritten)

The integration of Siri AI is a monumental step for Apple Watch. Previous watchOS versions lacked a modern AI input method, but watchOS 27 changes that. The current beta is still rough—especially Siri AI performance—but the direction is promising. The challenge will be making Siri AI as fast and reliable as on iPhone, without degrading existing Siri functions.

Beyond AI, watchOS 27 brings welcome refinements. The new Liquid Glass look improves visual clarity, and the single tap gesture builds logically on the double tap feature, making screenless interactions easier. The dynamic app grid takes some getting used to but becomes natural after a month of use.

However, a few misses exist. Double clicking the Digital Crown to jump between apps no longer works—it now opens the app grid like a single click. Users hope this functionality will return in a future beta. Additionally, watchOS 27 removes Walkie-Talkie entirely, leaving fans without a native push-to-talk solution. Third-party alternatives may not replicate the seamless experience. The update also lacks new watch faces, and third-party faces remain absent; Apple typically saves new faces for hardware launches.

Overall, watchOS 27 is a promising but unfinished update. Siri AI performance must improve before the public release, but the foundation is solid. For now, Apple Watch finally has a modern AI experience worth getting excited about.
