Apple Announces watchOS 4 for Apple Watch with Siri Smart Watchface, More

iOS 11's features will be improved slightly, with iMessages synchronizing with other devices and saving space by uploading old photos to the Apple Cloud.

Then comes watchOS 4, Apple's major firmware update for the Apple Watch.

As is becoming the trend, the portion of Apple's WWDC conference dedicated to the Apple Watch featured a heavy focus on the watch's health and fitness features, which continue to be the wearable's hallmark feature set.

In a bid that reminds us of the Google Feed, the Apple Watch now has a Siri watchface coming with watchOS 4. Here's everything we know so far about WatchOS 4. All Watches will be eligible to release the operating system for free once it is released in the fall.

The Apple Watch is being marketed as the "ultimate device for a healthy life". WatchOS 4 is the latest version of WatchOS.

Apple has shown off watchOS 4 at WWDC 2017.

WatchOS 4: When will it be available?

You can expect an update to WatchOS 4 to hit your Apple Watch Series 1 or 2 from "this fall". Dubbed watchOS4, the software brings a few new useful features. On the surface, you'll get watch faces powered by Siri that utilize machine learning to observe your habits over time and display the information you'll find most relevant. Previously you could only choose one exercise, say running, to track at one time. With the update, you can navigate through the album art by turning the Digital Crown.

The first announcement from Apple is a new watch face with Siri built-in. The Siri face also shows time sensitive content first and the remaining later.

Finally, the Toy Story watchface isn't the same as Micky Mouse - it features Woody, Jessy, or Buzz in some amusing animations. Do you think there will be more hidden features in the platform? Raise your wrist and you'll even see special animations with the characters interacting. Users will also receive unique Monthly Challenges designed just for them. Also, the new iPad Pro will feature increased compatibility with Apple's stylus, and the Notes app will now serve to register the user's handwriting. Moreover, more activity rings have been added with new celebrations as goals are completed. This is called Gym Connect - and it's not likely the last.

Apple is also teaming with a number of fitness equipment providers like TurboGym, which makes it possible to directly sync workout data back to the Apple Watch. Your heart rate is read by the watch and is sent to the equipment, and data and speed and other data is sent to your watch. The Music app supports multiple playlists, too.

In watchOS 4, the Music experience is getting a redesign and revamp.

Other noteworthy mentions in this update are the improvements to music management, the inclusion of a news app, and activity notifications. WatchOS 4 will also support native core Bluetooth.
