Apple today announced watchOS 6 for Apple Watches. The update adds a full App Store directly on the watch, offering independent apps, which no longer require a companion app on an iOS device. Apple also added a new streaming audio API for live sports and more as well as support for audiobooks. A new Noise app continuously monitors sounds levels to detect loud levels that could damage your hearing. Also new is a Cycle Tracking app for menstrual cycles and fertility, also coming to the Health app in iOS. A voice memo and calculator app have also been added, including a tip calculator.
