It looks like Google is gearing up for the Glass Explorer program, launching the MyGlass companion app and a new Glass setup page, both accessible to the general public.
The companion app relies on Google's now-signature "Card UI," and the listing's screenshots show off some of the app's functionality, though Google reminds us "if you don't have Glass, then downloading this will be a waste of time. Sorry about that." The description goes on to comfort readers, however: "But if you swipe the screenshots to the right, you'll see there's a picture of a puppy in pajamas. So not a total waste of time after all."
Of course, users can still install the app, though it (obviously) won't be able to complete Glass setup properly without an actual Glass unit.
