Just minutes into the opening keynote, the tech giant (AAPL) unveiled the latest iteration of its smarwatch operating system, watchOS 4. The software, which is backbone of the company’s Apple Watch, has a new watch face powered by Apple’s virtual personal assistant Siri. The feature learns how users interact with the device and provides relevant information throughout the day, based on what’s going on in the person’s day.

Apple Watch’s Activity and Workout apps, which provide fitness information, has added several features, including monthly challenges, which are meant to help users with their exercise routines. Apple’s watchOS 4 can also communicate with popular gym equipment so users can track their activity on a treadmill, elliptical, and other products. The feature will be available in the fall.
