Apple today released watchOS 9.4, the fourth major update to the watchOS 9 operating system that first launched last September. watchOS 9.4 comes two months after the release of watchOS 9.3.
watchOS 9.4 can be downloaded for free through the Apple Watch app on the iPhone by opening it up and going to General > Software Update.
