Apple at its WWDC 2021 developer conference this week unveiled watchOS 8, and made it available to testers. A public beta will be released in July, before general availability this fall. The latest version of Apple's watch-focused operating system is aimed at helping users "stay healthy, active, and connected." It includes a redesigned Breathe app that is now called Mindfulness, an upgraded Home app, and Messages with support for GIFs. (Credit: ANI)
