Felipe Costa has added another way for teaching Jiu-Jitsu to his fans.

The black belt is launching an iPhone App.

Two times world champion, Costa focused on techniques for passing the guard in his first App.

The application is a digital version of one of Felipe’s personal training program seminars.

Here is a video of the App.
