WWDC 26: Apple previews upcoming smartwatch update, focusing heavily on Siri and Apple Intelligence
Apple’s WWDC 2026 keynote was a departure from the norm. Instead of the usual segment-by-segment breakdown detailing exactly how your Apple Watch will track your next workout or monitor your heart rate, the Cupertino brand spent almost its entire presentation focused heavily on Siri and the broader rollout of Apple Intelligence.
This hyperfocus on AI means its smartwatch ecosystem is heading into the next software generation a bit blind when it comes to traditional health and fitness overhauls.
However, beneath the overarching AI narrative, Apple officially confirmed the arrival of watchOS 27 and provided a clear picture of how artificial intelligence will live on the wrist later this year.
This guide serves as the hub for everything you need to know about the next Apple Watch update, including the rollout of developer and public builds, compatibility demands, and all the exciting features coming this fall.
When will watchOS 27 be released?
The final, polished version of watchOS 27 will almost certainly roll out globally in September 2026. Interestingly, although the Digital Markets Act (DMA) will delay Apple’s rollout of the revamped Siri AI on iOS and iPadOS in the EU later this year, watchOS is confirmed to be unaffected.
So, with that, we’re still expecting the software rollout to coordinate with the arrival of Apple’s next-generation hardware line, which should include the Apple Watch Series 12 (and perhaps even an Ultra 4).
And because the WWDC 26 keynote lacked the typical granular breakdown of upcoming native apps and upgrades, we may see Apple quietly reveal specific sports and wellness upgrades via developer beta document drops over the summer.
To be honest, though, we’re in slightly uncharted waters here; WWDC has always given us a ton of insight into what to expect from the software edition landing later in the year. This time, we have the more humble list below.
What about the developer beta?
If you’re eager to test the new software, Apple has launched developer testing for the new Siri AI features starting today across iOS 27, iPadOS 27, macOS 27, and visionOS 27.
However, Apple Watch fans will have to wait just a little longer, with the company stating that Siri AI features will drop in a future watchOS 27 beta rather than in today’s initial build.
Device compatibility for Siri AI features
Apple has also confirmed the baseline requirements for its latest AI-powered features—and there’s quite a lot of older hardware being left behind.
Users who enable Apple Intelligence on supported products will gain full access this fall across the entire software family (including iOS 27, iPadOS 27, macOS 27, watchOS 27, and visionOS 27).
However, running the new Siri AI features requires substantial processing power. For its smartwatch ecosystem, Apple Intelligence and Siri AI are only supported on the Apple Watch Series 10 or later, the Apple Watch Ultra 2 or later, and the current-gen Apple Watch SE 3.
Crucially, these Apple Watch models must also be paired with an Apple Intelligence-enabled iPhone nearby to process workloads—and that’s limited to iPhone 16 models (or later), iPhone 15 Pro, and iPhone 15 Pro Max.
New features coming in watchOS 27
While the stage presentation was light on fitness-related announcements, there was a robust list of core upgrades, Smart Stack changes, and under-the-hood performance tweaks that have been confirmed for watchOS 27.
As we mentioned above, we may see more feature upgrades confirmed over the summer, so we’ll update this section if and when we know more.
- Siri AI on the wrist: The Apple Watch will support a custom-tailored version of Siri AI optimized for smaller screens (shown above), allowing users to ask complex contextual questions and trigger actions from the wrist. Conversations will also sync across iOS and macOS via iCloud.
- Private Cloud Computing: To power these heavy Apple Intelligence features without draining the smartwatch’s battery life, data will be processed via Apple’s Private Cloud Compute rather than on-device, ensuring it remains completely inaccessible to Apple or third parties.
- A new layout: Siri AI will be accessible from a completely redesigned, dynamic app grid layout—shown in our lead image above.
- Menopause alerts: The native Health app is expanding its women’s health suite, adding the ability to detect and alert users to early signs of perimenopause and menopause.
- Smart Stack upgrades: The Smart Stack is getting smarter with dynamic suggestions, alongside the ability to display transit cards and digital IDs right in the widget rotation.
- System efficiencies: Early hints suggest improved overall battery efficiency, more accurate step tracking, faster app extension launches, and more efficient water detection.
- Everyday features: The update brings a consolidated Find My app, a new guest key function, viewable card balances in the Wallet app, and a new tap gesture. GymKit is also expanding directly to the iPhone, freeing it from being an Apple Watch-only feature.
The Wareable take: Siri overhaul steals the show
Apple is clearly prioritizing its broader AI narrative over individual device ecosystems this year. It’s a logical defensive move against Google and Samsung—especially given the tumult surrounding Siri/Apple Intelligence over the past couple of years.
But for Apple Watch users eager to learn what’s coming, this presentation leaves many questions unanswered. We didn’t get the usual deep dive into new fitness-tracking metrics or updates to the newly launched existing tools and native apps.
So, at least for now—and possibly this year—the focus is all on how Siri will improve the Apple Watch experience. Providing you have compatible devices, of course.
We’ve already got a quick glimpse into the everyday tricks it will power. However, the real test of the summer beta cycle will be whether Apple Intelligence can actually make fitness and health data more useful—perhaps by using Siri to interpret complex health trends on the fly—or whether watchOS 27 is simply a foundational bridge year for the platform as Apple plays catch-up.
Only time will tell, but we’ll be tracking all the latest watchOS 27 news from now until public rollout. Stay tuned for more.
