Wallpaper changer 2.3 Apk

Have you ever searched on the market an application to change the background at regular intervals of our beloved cell phone? All right. Either you are in charge or have very limited or, finally, are full of bugs. With this app you can do this with a minimum battery consumption and by setting only two parameters such as time and the display mode.
Nothing else. I hope that the simplicity and convenience are the best weapon for this application.
