iFond Wallpaper Changer is a free Android application that allows you to personalize your device with your favorite photos. Developed by Artemis Beefeater, this app lets you select your preferred images and choose the best fragments that fit your screen. You can set them to change on the lock and/or desktop upon any timed interval.

One of the best features of iFond Wallpaper Changer is that it uses original unmodified photos from the gallery and does not save any cropped intermediate images, thus keeping your memory clean. You can also set several different fragments from one photo, like two sides of one wide landscape picture. Additionally, the app is free, with no ads or trackers.
