Best Wallpapers for Android helps you get some holiday cheer on your home screen
It's a very straightforward app; you get a list of categories, including Recently Popular, All Time Popular, Nature, Babes (yes, it has babes, but they appear to be mostly clothed) and a whole bunch of other categories.
At this time of year, the Recently Popular category is chock full of Christmas goodness, which is where the "holiday cheer" comes in. If you're looking for great Christmas wallpapers for your Android device, you've just hit the jackpot.
Bottom line: Simple and well-made. And I like my new wallpaper with the cute puppet (top-left in the screenshot).
