Framer allows you to set custom overlays on your Android Wear device.
Don't like the square screen? Add some round corners!
Would you like to know what your app looks like on a round device and only
have a square one? Set a round frame.
There are a few overlays to choose from. With the PRO version of Framer
you are also able to set your own images as an overlay.
320*320px 32bit PNGs with alpha channel are recommended. You can get
the unlocker for the PRO version either in the app or here:
