As many of you have already noticed, iOS7 brings in certain limitations in part of using an image as a wallpaper on the lock screen or home screen.

Particularly, if the image has different proportions than the iPhone's screen then it is scaled and positioned so that the entire screen is covered with it, cutting the edges of the image off.
Such a cropping is applied to almost any image you might want to use as a wallpaper, even those taken with the iPhone itself, because in most cases images are much more rectangular than the iPhone's screen.

I don't like the way iOS is limiting me in that. And I know many people don't like it too, considering how often this question is raised on the internet.

So I made this simple app to allow anyone make their own iPhone wallpapers, freely composing images from your photo library, scaling and rotating those as you wish.
It could be a single image or a photo collage made from multiple images. All positioned and scaled in any crazy way you like, without any limitations.
A very simple app serving a simple purpose.
And I really hope someone will find this app useful.
