Apple today released the fourth beta of watchOS 5.3 for testing on the Apple Watch. This comes a couple of weeks after the third build was seeded.
The new software can be installed by going to the Apple Watch app on your iPhone and searching for a new software update. You’ll have to have your Apple Watch connected to its charger in order for the update to install.
With this update, it’s expected that Apple will include bug fixes and security improvements. Of course, if any user-facing changes/features are spotted in watchOS 5.3, we’ll let you know.
