Wallrox Wallpapers has far fewer images available by default than others here, but it's for this curated approach and the overall design of the app that we've decided to include it in this list. Wallpapers are divided into categories of image type (Blur, Christmas, Crystal, Geometric, etc.) rather than what it's a picture of, and you can select how many columns of images you want to display on the screen at once. There's also an integration with Pushbullet, if you want to get notifications when new wallpapers are available. You can control some Muzei settings from within Wallrox too, like controlling which categories of wallpapers you want to automatically update, how often and on what type of connection. It's not as fully-featured as some of the others in this list, but it's well worth a look and stands above many, many more basic ones. Wallrox can integrate with both Pushbullet and Muzei / © AndroidPIT
