Wallpaper Engine is an application for Windows and Android that allows users to use and create animated and interactive wallpapers. It was released as a paid product on Steam in October 2016 as an early access title and left its early access stage in November 2018. The wallpapers are shared through the Steam Workshop functionality as user-created downloadable content. Wallpaper Engine comes with a powerful editor for turning static images into complex animated sceneries. It also allows users to customize the look and feel of their wallpapers. The core of Wallpaper Engine is highly optimized for performance and will automatically pause when playing games or using maximized apps to ensure high system performance. The Wallpaper Engine mobile companion app allows users to import their live wallpaper collection onto their Android device with ease.
