自動壁紙チェンジャー is a utility tool for Android that allows you to automatically change your wallpaper at regular intervals. With this app, you can select the update interval and the source of the wallpapers, which can be from your device's memory, SD card, or the app's dedicated folder. There is no limit to the number of wallpapers you can have, as long as they fit within your storage capacity.

One of the key features of this app is that it automatically resizes the images to fit your desktop screen size. This ensures that the wallpapers always look great and are not stretched or distorted. Additionally, you can create your own wallpaper sets by transferring images to the app through the "Share" icon.

自動壁紙チェンジャー also offers a widget that allows you to change the wallpaper instantly with just a click. However, to preserve battery life, the wallpaper change is paused when the screen is turned off.

Please note that the developer has released 自動壁紙チェンジャー３, and as a result, updates for this version have been discontinued. It is recommended to use 自動壁紙チェンジャー３ for future use.
