In addition to the Siri watch face, new Toy Story watch faces bring to life favorite Pixar characters including Woody, Jessie and Buzz Lightyear, while the Kaleidoscope watch face turns static images into mesmerizing patterns.

Perhaps the biggest update WatchOS 4 will bring to the Apple Watch is dynamic watch faces. Instead of using their arms to portray the hour and minute hands, the faces are fully animated and feature fun little vignettes when you activate them.

They may seem like small changes, but Apple obviously felt the need to add more inspirational tools into the Activity app to keep its native app fresh and competitive.

The Activity app has also gotten a minor update with watchOS 4. Whenever you achieve any of these, the watch will display a pretty new animation.
Finally, there's a redesigned app dock in watchOS 4, which will let you scramble throw your apps by simply rotating the dial on the side.
