watchOS 27: Siri AI Is the Headliner, but the Small Stuff Might Win Me Over

Apple has posted its watchOS 27 preview, and the marquee feature is exactly what you'd guess from the headline on the page, an all new Siri powered by Apple Intelligence. The full release is coming this fall, though the part everyone wants, the smarter Siri, is arriving in English later this year rather than at launch.

That gap matters, and I'll come back to it. First, here's the short version of what's new.

Siri AI is the big swing

This is the feature Apple is leading with, and it's a real rethink of what Siri does on your wrist.

Siri AI is conversational now, so you can ask open ended questions, brainstorm things like a workout routine, and go back and forth naturally instead of firing off one rigid command at a time.

A few capabilities stand out.

Siri can tap into your personal context, meaning you can ask it to surface your driver's license number, the door code for an upcoming rental, or a detail buried in a note.

It can take action inside apps, like sharing your flight details, starting a song, or setting an Activity goal. And it can pull from broad world knowledge online to answer questions on the fly, which is the kind of thing the old Siri would punt to a web search.

This is genuinely the upgrade Apple Watch Siri has needed for years. But Apple is clear that Siri AI is in beta and English only to start, and it won't be in the EU on iOS and iPadOS initially.

So the wrist gets the most ambitious version of Siri ever, on a timeline that's a little fuzzy. I'm hopeful, but I'm reading "later this year" with the patience it deserves.

A dedicated Siri app

Alongside the smarter assistant, there's now a Siri app that collects your conversations in one place.

You can start a question on your iPhone and pick it up on your watch, pin the chats you want to keep handy, or kick off a new one straight from your wrist.

Pairing that with the new dynamic app grid, which automatically floats your Siri suggested and most used apps to the front, the whole interaction model on the watch is clearly being reorganized around Siri.

The small refinements I actually care about

This is where watchOS 27 wins me over.

The new single tap gesture lets you tap your index finger and thumb together once to select a widget in the Smart Stack, even when your other hand is full.

If you've ever tried to do anything on a watch while holding a coffee and a leash, you get why this is great.

Smart Stack suggestions are smarter too, surfacing things like a contact's birthday, your parked car's location, or your transit card balance when they're relevant.

Find My now consolidates devices, people, and items into one map first view.

Liquid Glass got a readability pass with more even refraction and better contrast. And Call Context can surface useful info while you're on a call with a business, like pulling a confirmation code from Mail when you ring an airline, though that one is coming in English.

There are quiet quality of life wins, too. Music playback starts faster, and the Fitness app's step count now syncs with Health.

Health and fitness keep marching forward

Workout Buddy gets new insights drawn from your fitness history covering pace, distance, and workout duration, it now works without your iPhone nearby, and it speaks Spanish.

Indoor run and walk distance tracking is more accurate thanks to improved motion algorithms. And Cycle Tracking adds perimenopause and menopause support, with notifications when your logged patterns suggest perimenopause plus educational resources.

Apple is careful to note these notifications are for ages 40 and up and aren't a diagnostic tool, which is the right call.

Compatible Watches

watchOS 27 runs on

• Apple Watch SE 3
• Series 9
• Series 10
• Series 11
• Ultra 2
• Ultra 3

and it needs an iPhone 11 or later, or an iPhone SE second generation or later, on iOS 27.

The headline feature is the one with an asterisk on timing, but the bundle of smaller refinements feels like the stuff I'll notice every single day.

What about you, is Siri AI the reason you'll update, or are the gesture and Smart Stack tweaks the real draw? Let me know in the comments.
