Waste of Money
Load a photo, rotate it, zoom in, zoom out, do whatever you want. Save it to your photos. Then try to set it as your wallpaper on your iPad with iOS 7. It still does the same old thing. It will only display a small part of the photo. Theres still no way to scale the picture to fit the screen.
Also, there are no clear instructions about how to save the new version of the photo. And it seems like it replaces the old picture.
