Earlier this week at its WWDC keynote, Apple showed off watchOS 7.
watchOS 7 includes a bunch of new features, such as the long-awaited sleep tracking.
Your Apple Watch will have a Sleep app, letting you mark your bedtime and time that you want to wake up.
Your Apple Watch will also give you a warning if you go to sleep with less than 30% battery life.
Faces can now have more than one complication from one app, and there's a new UI for configuring your watch face.
