WatchOS 2 is the second version of the operating system that powers the Apple Watch lineup, and it arrives about five months after the wearable’s debut — and five days after it was originally expected. Even though it’s been only a few months since supplies caught up with the initial high demand, development of the underlying operating system has continued.
WatchOS 2 is designed to fix a few of the complaints rightfully aimed at the Apple Watch software and to tweak the feature list to better meet users’ needs. These changes should provide faster app launch times, more display-on time so the watch’s screen doesn’t turn off before an app loads, more comprehensive apps and better standalone functionality.
