A new "medical prediction" app aims to help you easily uncover what really comes between a boy and his Calvins.

Reportedly developed by a Toronto-based family physician, "The Predicktor" attempts to predict a man's penis size, using stats such as his height, sexual orientation and finger length while cross-referencing trends from scientific studies, according to its website.

Though the site stresses that the app is strictly for humorous purposes, Dr. Chris Culligan nonetheless tells Raw Story he also hopes the Predicktor to dispel myths and relieve the "penis-related insecurity, anxiety or dissatisfaction" men have about themselves.

“It’s not how long your pencil is, but how you write your name,” he says, quoting his father.

Though he says a man's race "has never been shown to be related to penis size in any reasonable published study," Culligan refers to studies that found that many gay men have longer, thicker genitalia than heterosexual men on average. “Gay pride just got a little prouder,” quipped Culligan.

At present, the app is only available for Androids. Check out its website for more information.
