Zen Budokai Jujitsu system chart helper. This app loads and displays jujitsu chart information. In the Zen Budokai Aiki Jujitsu system, different jujitsu techniques are organized into collections called charts. A technique typically is written in the form of an "attack" followed by a "defense". This app lists many of the available charts and for any chart selected lists the techniques on that chart. If a technique is selected the user can choose to have a "text-to"speech" synthesizer read the technique. Or a technique can be read at random.
