The $.99 iOS Smize Yourself app gives users lessons in how to “smize” through photos and videos. Users can then add their own images and the app will add a “smile.” These images can be shared with friends via Facebook and Twitter.

“On America’s Top Model, I’ve always told my girls to smile with their eyes. We call it `smizing.’ Over the years, it’s actually become part of pop culture,” Banks told USA Today. ”I would be walking down the street and girls would say, ‘Smize!’ So many people asked me, ‘Tyra, am I doing it right?’ I decided to do an app. It does it for you, but exaggerates it, and makes it more like a fun bar tool or at-lunch tool.”
