You call these junk wallpapers Retina? I checked the resolution and they are very low wtf. And the ad pops up way too much and cant even do anything. You gotta give some time until a user analyzes some walls before purchasing adfree. But of course you dont want them to analyze because the walls are not actually retina and they are junk!
