On devices that allow a rotation of the home screen, Wallpaper Rotate enables you to take full control of your wallpaper image in both portrait and landscape orientation. You can choose to enjoy the same image in both orientations but with different cropping to best suit the composition. Or you could opt for different images and enjoy both as your device orientation changes.
The full version - which is an in-app purchase - adds the ability to manually crop your selected images and also enables scrolling across several home screens.
This app is implemented as a live wallpaper. To access the wallpaper from any home screen, place a finger on the display and long press. From the context menu that appears select Wallpapers -> Live Wallpapers and choose Wallpaper Rotate.
Please note that this app builds on existing home screen functionality. It will not add the capability to rotate or scroll the home screen on devices where this is not supported.
