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.
