About this app

Kodokan Judo Theory is a structured study companion for students who want a stronger understanding of techniques, terminology, and core judo principles. It is built to help you revise with more depth than a simple glossary, and with more structure than scattered notes or saved videos. Whether you are preparing for grading or strengthening your knowledge between sessions, the app gives you a focused way to study judo on iPhone and iPad. Inside the app you can: - Review key judo techniques across ukemi, throws, groundwork, submissions, safety, scoring, and related study areas - Study each core technique with summaries, movement or step counts, signature ideas, end position notes, focus points, common mistakes, related techniques - Practice Japanese terminology with meanings, transliteration, flashcards, and audio support - Improve pronunciation and terminology recall alongside technical understanding - Revise important judo concepts such as kuzushi, tsukuri, kake, control, efficient movement, safety, randori, kata, and grading knowledge - Reinforce learning through quizzes covering terminology, theory, and technique recognition - Mark items as learning, confident, or mastered to make revision more intentional - Save favourites, return to weaker areas, and use built-in progress, XP, readiness, and streak-style study cues to keep momentum - Switch between supported languages for easier study and wider accessibility The app is designed to help you go beyond recognising throw names. It helps you connect Japanese terms to meaning, pronunciation, and real technical context, while keeping your revision organised and easy to return to. If you want a cleaner, smarter way to study Kodokan judo between training sessions, Kodokan Judo Theory gives you one place to review language, concepts, and techniques together. A practical study support for serious judo students.
