Apple on Monday released watchOS 10.3 to the public, its third major update to the watchOS 10 operating system that was released in September. watchOS 10.3 brings a new Unity Bloom watch face to celebrate Black History Month, as well as unspecified improvements and bug fixes.
watchOS 10.2 can be downloaded for free through the dedicated Apple Watch app on the iPhone by going to “General” -> “Software Update.” The Apple Watch needs to have at least a 50% battery charge, needs to be on a charger, and needs to be in the range of the iPhone.
