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.

Roller is an app to server as a journal for your Brazilian Jujitsu journey. There are 3 main things you should track. Classes, Rounds, and Submissions! Tracking them right after class is the best way to get accurate data. Use Classes to keep track of the moves you learned, track your comfort over time, and keep track of how many times you've drilled. Use Rounds to keep track of mat time, know that you're going to do differently against different belts. View rounds over time and see the difference between day one and today. Use Submissions to find your strengths and your weaknesses, find which submission you're caught in the most and which you land the most.
