watchOS 27: 12 New Things To Check Out on Your Apple Watch

Apple released watchOS 27 on September 14. The features and changes aren’t limited to owners of new Apple Watch Series 12 and Apple Watch Ultra 4 models. If you have an Apple Watch model that supports the latest update, here are 12 features and changes to check out after installation.

To do so, open the Watch app on your iPhone, then tap General ➝ Software Update, strap your watch into a charger, and follow the onscreen prompts.

Check Out the Dedicated Siri App

Siri has finally caught up with the AI revolution, and apart from having contextual awareness, it now has an app of its own that collects every conversation in a single view and syncs them privately across your devices over iCloud. Just ask something on your iPhone and you can pick the thread up again on your Apple Watch, as well as pin conversations worth keeping, or even start a new chat directly from your wrist.

Try Siri Modular Watch Face

The new Siri watch face is a genuinely useful one. Its rectangular complication shows you whatever sits at the top of your Smart Stack, and it automatically updates through the day based on time, location, and other factors.

The Dynamic App Grid

Pressing the Digital Crown no longer produces the honeycomb app view by default. Now, watchOS 27 shows a dynamic grid made up of suggested apps, your most-used apps, and your most recently used ones. The Siri app sits in the middle, but the alphabetical list remains available – simply turn the Digital Crown to navigate through all of your apps.

New Tap Gesture

Apple has added a third gesture to Double Tap and Wrist Flick. The new one is simply called Tap. A single tap of your index finger and thumb opens the highlighted widget in the Smart Stack. You can still navigate the Smart Stack with Double Tap and dismiss notifications with Wrist Flick.

Walkie-Talkie Has Been Deleted

Walkie-Talkie is gone, and not merely hidden. The app is unavailable after updating to watchOS 27 and cannot be reinstalled from the App Store. You can keep the app by staying on watchOS 26, but you won’t be able to start a conversation with a contact who has updated.

Live Rewind (Not Yet)

This is the change most likely to catch people out. In watchOS 26 and earlier, a double press of the Digital Crown opens the App Switcher, where you can jump back to the previous app, scroll through recent ones, and swipe to force-quit anything misbehaving.

That’s changed in watchOS 27, in which a double press shows the new dynamic app grid instead. The gesture has been reserved for Live Rewind, an upcoming feature (exclusive to Apple Watch Series 12 and Ultra 4) that produces a transcript of the last fifteen seconds of speech in your environment.

Fortunately, the App Switcher will still be available when watchOS 27.2 is released later this year, but it will open with a different gesture. If you’re already on the latest beta, simply long press on the bottom of the app that you’re in, and that should open the App Switcher.

Find My is Now One App

Find Devices, Find Items, and Find People have been folded into a single Find My app with a map-centric layout, which also includes shortcuts for directions and for items nearby.

Workout Buddy No Longer Needs Your iPhone

Introduced in watchOS 26, Workout Buddy previously required your iPhone within range. In watchOS 27, your Apple Watch can run it if Wi-Fi or cellular is available. It also draws new insights from your training history, tracking gradual gains in pace, distance and workout duration, and it now speaks Spanish as well as English.

New Cycle Tracking Features

Cycle Tracking in the Health app can now notify you if your logged patterns are suggestive of perimenopause, alongside symptom tracking and educational material. The notifications only draw on your logged cycle history and apply to users aged 40 and over. Apple says the feature is not a method of birth control and is not a diagnosis.

Treadmill Distance Is More Accurate

In watchOS 27, new machine learning motion algorithms measure distance more precisely for indoor runs and walks, and Apple says the improvement starts from the first step, as opposed to settling after a few minutes. Fitness route maps are more accurate too, and step counts finally stay in sync between the Fitness and Health apps.

The Smart Stack Gets More to Say

The Smart Stack’s contextual suggestions are now a lot smarter. A few examples provided by Apple include new widgets surfacing your parked car’s location, a close contact’s birthday, a change in your transit card balance, the Noise app immediately after a loud-noise alert, a reminder that Theater Mode is still on, pinned messages, celebrations, and identity cards.

New Models Get a Steps Counter

On Apple Watch Series 12 and Apple Watch Ultra 4, the redesigned pedometer model and S11 chip allow watchOS 27 to provide more accurate step counts. There’s also a new Steps complication on the latest models to track your steps in real time, right from your watch face. Will we see the feature come to older devices? Your guess is as good as ours.
