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.

• Round screen-borders of a square device
• Completely round display on a square device
• Some "prank"-overlays included, like broken LCD
• Set own custom overlays (needs PRO version)
