How many times you wondered how Santa keeps track of who’s been naughty or nice? There is an app for that. In the video below, the Naughty or Nice Live App helps Santa watch out for who’s been good or bad, delivering that information directly to a live tile on his bright red Windows Phone.

Santa Clause isn’t the only North Pole resident using Windows Phone. Earlier this week Microsoft posted a video of the Snowman using Windows Phone while at a speed dating event.

Jessica Alba, Gwen Stefani, and Will Arnett also currently appear in videos and ads where they show off how they use Windows Phone (in slightly warmer climates).

If you are interested there is also a Naughty or Nice Facebook app.

Have you been naughty or nice? Let us know in the comments.
