Apple today seeded the fifth beta of an upcoming watchOS 4 update to developers, two weeks after seeding the fourth beta and two months after introducing the watchOS 4 update at its 2017 Worldwide Developers Conference. 

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 needs to have at least 50 percent battery, it must be placed on the charger, and it has to 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 need to wait until the software sees an official release in the fall to try it out.
