This iPhone app will either put a literal smile on your face, or completely terrify you
That's not nearly all the app does, though the rest of the functionality borders on the terrifying. For example, it's able to age you like even a rigorous daily regimen of nicotine and regret won't. Or change your gender to the point where you see the result and start asking yourself some very uncomfortable questions. So we suggest sticking to the smiles and exploring the rest of the app while feeling particularly confident, or more than a little tipsy. FaceApp is a free download.
