Want to see what you'll look like when you're older? Or how'd you look if you were a member of the other sex? Of course, there's an app for that. Download the app called FaceApp. There's a free version, or pa $3.99 for an upgraded version. Available for both iOS and Android, it uses artificial intelligence to take the photo of your choosing and show you what you’ll look like when you get old, what you’d look like as a male or female, or even make you younger looking.
