You train three times a week. Ask yourself what you got caught with last month. Most of us can't answer. The rounds blur together, the same mistakes keep happening, and progress feels like luck. Rolls is a training log and technique library built for BJJ. Log your session in a minute after class. Over a few weeks your game shows up in plain numbers: what you finish, where you get tapped, which positions you win and which ones you lose. Pay once. No subscription. No account. Your training stays on your phone. LOG A SESSION IN A MINUTE - Time spent drilling, positional sparring and rolling - Submissions you finished and submissions you got caught in - Positions you won and positions you lost - Notes for the details you want to remember - Add your own positions if something is missing SEE YOUR GAME - A-Game: the submissions and positions that work for you - To Improve: where you keep getting tapped or losing position - Switch between this week, this month and this year - A calendar with every session and a weekly goal ring for your training days - Share a session card when you have a good week STUDY THE MOVE, NOT THE INTRO - 100 positions across guards, top control, leg entanglements, submissions and standing - Each one breaks down the key details, common setups, what goes wrong and how to fix it - Over 100 short videos walk through the transitions step by step, with no intros and no filler SHOW UP ON YOUR DAYS Pick the days you train and Rolls reminds you that evening to log the session while it's still fresh. YOURS FOR GOOD One price, every feature, every update. No subscription to cancel, no sign-in, no account to lose. Technique videos stream, so they need a connection. Everything else works offline. Built for every belt. White belts use it to see their first patterns. Blue and purple belts use it to find the holes that keep costing them rounds. Brown and black belts use it to keep the details sharp.
