In this iteration at least, Android Wear has taken an Apple (simple) approach and Apple Watch has taken an Android-of-old approach (more complex). Android Wear doesn't have an app launcher except for a buried start feature in the options menu. Android Wear is not supposed to be used to launch apps. It's supposed to be an accessory to your phone, showing you phone notifications and allowing you to respond and address things that pop up. It is mainly interacted with by vibrating and showing you a notification and swiping it away. Or by talking to it by holding it up at the angle you'd look at a watch and saying OK Google followed by "Text Susan I'll be 5 minutes late" or "When did Georgia become a state" or "How do I get to the nearest post office". For the final one, a single tap confirms that you want to enter navigation mode. One of my friends loves his. I got one for developing but haven't used it much.

The array of app icons and the crown on the Apple Watch makes it seem like it's trying to take over functionality that is much better handled by your phone with its larger, more mature UI. Perhaps the end goal is that Apple Watch is supposed to be more of a standalone device, which is why it has beefier hardware and a much beefier price tag (starting at $349 as opposed to the $80 I got my LG G Watch for).
