Judoka is a fast, beautiful reference for judo — every technique, every term, every list you need on the mat, fully offline. TECHNIQUES Browse the complete canon of judo techniques, organized the way judoka actually think about them: by family (nage-waza, katame-waza and their subdivisions), or alphabetically. Every technique includes a plain-English description, its classification, direction of movement, and official IJF code. COMBINATIONS & COUNTERS See how techniques connect: each entry links the combinations it chains into and the counters that answer it, with short practical notes. COLLECTIONS Techniques are cross-referenced into the lists that matter — the Kodokan syllabus and dai (Gokyo groupings), USJF and USJA rank curricula, and more. Build your own custom collections for your club's syllabus, your competition arsenal, or your next grading. TERMINOLOGY A complete Japanese–English glossary of judo terms — etiquette, commands, anatomy, philosophy — so you always know what was just shouted across the dojo. RULES AWARE Techniques banned or restricted under modern competition rules are clearly flagged, derived from the actual rulesets — so you know what scores and what gets you penalized. MADE FOR THE MAT • Works fully offline — no account, no ads, no tracking • Instant search across techniques and terminology • Favorites for quick access • Designed for iPhone and iPad Whether you're preparing for your next belt, coaching a class, or settling a debate about whether that was really kata-guruma — Judoka has the answer.
