Make fun of your friends by getting them to think this application can test their personality. You can find out if they are smart or dumb, beautiful or ugly, popular or geek, funny or boring, awesome or awful.
Preset the answers in the settings menu and then scan their finger. The application will respond according to the settings. If nothing was set, the answers will show up randomly.
You can also select what you want to detect.
