watchOS

watchOS is the operating system that runs on the Apple Watch. It’s a simplified version of iOS designed to run on a small screen.

It has many of the same apps, like Mail, Messages, Find My, Calculator and more. Extra features are tailored to the Apple Watch, like the customizable watch face, health sensors and Digital Crown.

New features coming soon.

watchOS 26 is the next major update currently in beta testing. It is expected to be released in September, 2025. It includes:

  • Workout Buddy, a feature that gives you personalized encouragement during a workout.
  • The Notes app comes to the Apple Watch for the first time.
  • If you leave your watch sounds on, it’ll automatically adjust the volume to match the ambient volume of the room.
  • Messages now includes custom backgrounds and message translation, like iOS.
  • On Apple Watch Series 9, Ultra 2 or later, you can flick your wrist away to dismiss a notification.
  • The Watch Face Gallery has been redesigned with faces sorted into different categories.
  • You can choose a workout playlist that plays automatically when you start a workout — or choose a recommended playlist based on the workout type.

Everything new in watchOS 26: Workout Buddy and 15 other features

watchOS 26 is a more modest update with one headlining new feature, Workout Buddy — on top of 15 other new tweaks. You might overlook the Apple Watch after the excitement of Liquid Glass on your iPhone and Mac, but your tiniest screen still has some stuff worth checking out. 

There are loads of smart new features for those with the latest and greatest. A new wrist flick gesture silences timers and calls. Your volume automatically lowers in quiet rooms. And everyone can appreciate that the Notes app finally makes its way to the watch. 

The update is out now; here’s what to expect. 

How to download the watchOS 26 public beta

You can download the watchOS 26 public beta right now. With it, you can try out the great new Liquid Glass design coming to the Apple Watch before Apple ships the update to everyone. And you can check out Workout Buddy, the AI-powered coach that gives you encouragement during your workouts.

Of course, there are a few things you should look out for. Beta software is buggy and can lead to data loss or apps that don’t work. This particular beta is a rough one, with lots of broken animations and features. A lot of apps you use probably won’t work correctly. I strongly recommend that you at least wait for the public beta — it’ll be available starting in July.

If you’re still sure you want to try it out, you’ll need to install iOS 26 on your iPhone first. I’ll show you how.

All the sweet new watchOS features we expect at WWDC25

What's in store for the next version of watchOS? A big name change might be just the start.

There’s less than a week to go until WWDC, the annual developer fest where Apple takes the wraps off its latest OS releases. While the rumor mill has mostly focused on iPhone this year, there’s plenty for Apple Watch fans to look forward to.

Rumor has it that the next big watch update — possibly dubbed “watchOS 26,” in line with Apple’s rumored naming convention shakeup — will get a fresh new user interface, Apple Intelligence, conversation transcriptions and a smart AI coach that delivers tailored health and fitness advice.

Let’s roll up our sleeves and take a closer look at what’s in store for Apple Watch.

Apple might switch all OS version numbers to years

Apple might make a major change to the naming convention for all its operating systems this year, switching all OS version numbers to years, according to a new report. The switch, which Apple reportedly will roll out at WWDC25 on June 9, would bring consistency across all its operating systems for the first time.

10 years of Apple Watch history: A timeline

For the 10th anniversary of its launch, we compiled over a decade of Apple Watch history into a quick timeline. Starting with the original three collections — including models in solid 18 karat gold — all the way to today’s far more advanced (and sensible) Apple Watch Series 10 and Ultra 2.

The Apple Watch was the first major product introduction of Tim Cook’s reign as Apple CEO. There was immense pressure on Apple to prove that it could still innovate without Steve Jobs. While the Apple Watch wasn’t as flashy as the iPhone and iPad, it’s grown into an incredible business rife with breakthrough technology, in one of the most physically constrained form factors yet.

Apple issued emergency software updates Thursday for iPhone, iPad and Apple Watch that patch security vulnerabilities the company says may have been actively exploited. Among other things, the release notes for iOS 17.0.1, iPadOS 17.0.1 and watchOS 10.0.1 indicate the updates fix a problem that could allow a malicious app to bypass signature validation.

The updates, which Apple recommends all users download as soon as possible, come just days after the company pushed its latest operating systems live. However, if you plan to pick up an iPhone 15 tomorrow, you might want to hold off. If you update your current phone to iOS 17.0.1, you would need to update your new iPhone as well before setting it up from a backup.

WWDC23Despite dumping massive engineering resources into its brand-new visionOS platform for the Vision Pro headset, Apple is bringing loads of new features to iOS, iPadOS, macOS, watchOS and even tvOS this year. Headlining features include NameDrop, StandBy, Journal, Live Stickers, pet tagging in Photos and blurring unsolicited nude pictures.

However, Apple didn’t have time during its jam-packed WWDC23 keynote this week to cover all the new features. Now that iOS 17 is out, here are some of the hidden gems people have discovered in Apple’s latest operating systems.

The first betas of iOS 16.6 and macOS Ventura 13.5 went to developers on Friday. The same is true for iPadOS 16.6 beta 1, watchOS 9.6 beta 1 and tvOS 16.6 beta 1.

The timing might seem odd because Apple is expected to unveil iOS 17, macOS 14 and the replacements for its other operating systems in a couple of weeks, but this is normal.
