Nudifier can do a lot of things, but one thing it can't do is work like an X-ray type of app to show you what's under someone's clothes. I wish that's how it works, since it's advertised as an app that can turn any picture into a sexy naked photo, but unfortunately, it can't do that.
Instead, it 'nudifies' photos in an entirely different way. Remember how TV channels pixelize stuff to censor out faces and body parts so they can still show it on cable? Well, now you can do that to any picture you want to with Nudifier.
All you have to do is open up the image you want to nudify, select the matching skin tone of the person who you want to mess with, and hit the orange camera button for instant nudification.
It's obviously not what you expected, but give it a shot and use your imagination. You'll be surprised at the results. You can get the Nudifier app from the iTunes App Store.
