An almost full-fledged Google Maps app pops up on Android Wear
Version 9.9 of Google Maps for Android brings a dedicated Google Maps app straight to Android Wear that can either be fired up by launching it from the drawer or by saying "open Maps" when your smartwatch is listening to you. Previously, you could only get directions to a specific location, but now you can experience a mostly full-fledged version of the app, which allows you to browse it
Core Google Maps features like pinch-to-zoom, true north/ device direction switching, and scrolling around are on board; you also get a handy virtual zoom in/out buttons and a power-saving display mode, which displays the map in black and white. Still, the app is quite limited at this time - if you opt to start navigation from Google Maps on your watch, it redirects you to your phone and opens app on it.
It's also worth saying that actually getting the app on your Android Wear watch is a bit tricky (just as anything Android Wear-related). First of all, you need to have Maps v9.9 on your phone, then you need to re-sync your apps, and finally, if you are lucky, a simple restart of the smartwatch will do the job and bring Google Maps on your smartwatch.
