The whole TAGB syllabus in your pocket, from your first lesson to 5th Dan. Fifteen grades, 10th Kup white belt through to 5th Dan. For each one: what the belt colour means, the pattern you are learning, the Korean terminology that grade introduces, and the line work you will be asked for. PATTERNS All 26 patterns, move by move — 994 movements in total, each one numbered exactly as the syllabus numbers it, with its ready posture and movement count. From Chon Ji's 19 moves to Ge Baek's 44. KOREAN 206 terms with their meanings, filtered by belt so you only see what your grade asks for. Stances, blocks, strikes, kicks, and the vocabulary of the dojang. BUILT FOR THE DOJANG Everything works offline. No account, no sign-in, no setup. Made to be readable at arm's length on a hall floor. NO ADVERTS. NO TRACKING. NOTHING COLLECTED. This version removes every third-party framework the old app carried. No adverts, no analytics, no crash reporting, no identifiers. The app stores nothing at all — not even your place in the syllabus. FOR TAGB AND ITF STUDENTS The grading structure and line work follow the TAGB syllabus. The patterns and Korean terminology are common to ITF Taekwon-Do generally, so students in other ITF associations will find most of it applies to them too. ALSO FROM APPYAPPSTER TKD Quiz — 251 questions across the colour-belt syllabus, scored grade by grade.
