The hardest part of improving at jiu-jitsu is not finding more techniques. It is knowing what to focus on, remembering the details that matter, and turning training into steady progress. Kaizoto is built around three things: focus, techniques, and tape study. FOCUS Keep your current training priorities clear. Track what you are working on, what needs attention, and where your game is developing. Instead of collecting random notes, Kaizoto helps you stay connected to the specific areas you want to improve. TECHNIQUES Build your personal technique library. Save positions, attacks, escapes, transitions, and details in a structure that matches your game. Organize techniques into folders, attach media, add notes, and keep the important details easy to find when you need them. TAPE STUDY Study your own footage. Upload training clips, pause on key moments, draw directly onto the video, and record voice notes as you analyse what happened. Use tape study to close the gap between how a roll felt and what actually happened. Kaizoto is for practitioners who want a clearer way to train, review, and improve over time. Small improvements compound. Kaizoto helps you keep track of them. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
