OnePlus WellPaper is available for all Android devices and aims to change wallpapers according to your usage. It uses the data that your phone displays on the screen and organizes them into 6 categories - social, lifestyle and communication, entertainment, gaming, information and tools. Each category has its own colour.
OnePlus said that the application does not consume a lot of battery, as a live wallpaper would. This is because WellPaper animates the wallpaper only when the phone is turned on.
