Ehh... – Retina Wallpapers Free - HD Wallpaper for iPhone, iPod and iPad, customize and edit High Definition pictures and photos in iOS 7 and iOS 6, Lock and Home Screen Wallpapers optimized for Retina Display Review

I guess because it's a free app I don't have much room to complain. I wouldn't label this as a "retina display" wallpaper app, however. Most of the wallpapers I viewed were distorted or a little fuzzy. None of the abstract photos were even close to high quality. Overall, this app is mediocre.
