It is an App installed on current iPhones, iPads, and Apple Watches. It just outlines features in the products, e.g. new iOS 15 features, “Essentials”, What’s new in watchOS 8, “Health”, “Beyond Basics”, “AirPods Max”, “AirPods”. I think various sections show up depending on what you buy or add to your Apple ID, and usually I’m able to learn a few things a year from it that I missed in the announcements or didn’t see covered elsewhere.
