Apple today seeded the third beta of an upcoming watchOS 4 update to developers, just over three weeks after seeding the second beta and more than a month after introducing the new update at its 2017 Worldwide Developers Conference. The new version is build 15R5321h.

Once the proper configuration profile has been installed from the Apple Developer Center, the watchOS 4 beta can be downloaded through the dedicated Apple Watch app on the iPhone by going to General --> Software update.


To install the update, the Apple Watch must have 50 percent battery, it must be placed on the charger, and it must be in range of the iPhone.

watchOS 4 features three new watch faces, including a dedicated Siri watch face that displays dynamic information unique to each individual and is perhaps the most significant new feature in the update. There are also new complications for Now Playing and Apple News, and an enhanced Workout app that supports High Intensity Interval Training and new swimming options.

Gymkit, a new technology platform, will let the Apple Watch interface with gym equipment for workout data sharing purposes, and the Activity app will offer up intelligent coaching and tailored workout encouragement along with new monthly activity challenges.

Many other small tweaks and changes have been introduced, all of which are outlined in our dedicated watchOS 4 roundup.

watchOS 4 is only available to developers and will not be provided to public beta testers, so non-developers will need to wait until the software is officially released in the fall to try it out.

Installed and left over night.

Woke up and progress was on 100% on the ring / apple watch. Waited another hour. Nothing. Pressed crown and side button till it turned off. Turned on, entered pin and working again.

One to watch out for if anyone gets those symptoms. :)

For a second I thought it had bricked! phew!

Much needed. Slightly later than expected, but here none the less.

The release isn't even showing up in updates yet so it may have just been released. It keeps saying watchOS 4 is up to date.
