The release of the watchOS 10.1 beta to developers on Wednesday brings the cool new “double tap” gesture that allows one-handed use of Apple Watch in certain cases (though it can’t be enabled yet).
In other words, it’s a way to operate the wearable without touching its screen. And once iOS 10.1 arrives in October, Apple Watch Series 9 and second-gen Apple Watch Ultra users can try it. However, even folks with older Apple Watches can try a version of it right now.
