Whats fascinating and somewhat confusing is that so many of the Watchs core abilities are only in the Watch app, so interface ideas you learn there dont work anywhere else.
For example, the Watch app is the only place to access notifications after they appear. Notifications are the most important part of any smartwatch experience, but on the Apple Watch you can only swipe down to see your notifications when youre on the watch face. Once you click the Digital Crown and open the app launcher, the notification drawer goes away entirely and swiping down does nothing. Same with Glances, which are essentially single-screen status updates from various apps you access by swiping up from the Watch app. Theyre a major piece of the Watch experience, but they disappear everywhere else in the operating system. These are radically different interface patterns than iOS, where you can access the notification center and control center from virtually everywhere, and it makes navigating the Watch interface more confusing until you get it.
