Some of the services available in Channels include HBO, Showtime, CBS All Access, Nickelodeon, Epix, and Starz.

Other features of Apple's new TV app include Family Sharing, which lets up to six family members share subscriptions using their Apple ID and password, and the ability to download shows and movies for offline viewing. There's also a dedicated Kids section that highlights handpicked shows and movies for children.

Apple is releasing watchOS 5.2.1 for the Apple Watch today, too.
