When I was using Pebble I used the Glance watch face. A nice feature of this was the ability to push the side buttons to do custom things. I had a semi-complex setup with Pebble Tasker so that when I hit the bottom button it would launch a menu screen, which would then allow me to pick a sub-menu, and then pick one of three options from there. I had, in essence, 9 "quick links" that either stated a phone call or adjusted audio settings on my phone or performed a basic task with my home automation.
All this can be done on Android Wear as well, but not nearly as quickly using the standard Android Wear interface. I've used a couple of other launchers and while they worked well enough, this one has some nice advantages. Specifically:
1. The ability to arrange the links how/where I want them. Others usually only let me put them in alpha order or most used order.
2. The ability to have 8 options on one screen. Others it's usually 4 or 6.
3. The ability to launch phone apps from my watch.
4. The ability to turn on/off things like WiFi and Toggle Audio states.
Now, having sung the praises so far, things are all rosy. There's still a few things missing, in my humble opinion:
A. Tasker integration. I want to be able to add tasker tasks as shortcuts. (The developer has said this is coming.)
B. Change images. I'd love to setup some "quick call" buttons have them be pictures of the people.
C. Option to auto-exit the launcher after a choice has been selected.
Over all I'd give it 3.5 out of 5 stars. It's best Wear launcher I've found so far, and given it's very young state it's a great start. But there's room for polish and improvement.
