The Elf on the Shelf is everywhere. That's kind of the point, right? It bounces around various spots in your home until Christmas, keeping an watch on who's naughty and who's nice, reporting back to Santa each night before staking out a new hiding place. You can't hop on Facebook or Instagram or walk through a store without seeing one of these things.
And, yes, the Elf has an app. A game, actually, with the slightly double-entendre'd title of "Slide n' Glide." (Remember, even Santa has a naughty side, too.) The premise is you move the Elf to determine how far a package will fly off a chute and onto a platform. Get all the presets loaded, and you move onto the next level.
It's a simple (and free!) game, and adults won't get much out of it. But your kids? Chances are we just found another reason they'll be fighting you for the phone. (Plus there are more than Slide n' Glide available.) We've got some demo video on a Galaxy S3 (the game apparently is having issues on some phones) after the break.
