Kata Book Stay

Kata Book is an offline-first martial arts forms and grading syllabus book for students who work one named belt track at a time. See exactly which kata keep you exam-ready and which have gone cold—before grading day, not after. Cold start opens a fullscreen belt-syllabus ladder: a vertical dojo-mat view of ranks from white belt to your current goal. Each rung shows required kata chips, practice freshness dots, and a readiness percentage ring toward the next grading. Stale-form badges bubble up anything outside your freshness window so weak spots are obvious at a glance. Set your active belt track with style name, current rank, next grading target, and custom rank labels that match your school. Browse the kata library per rank with short sequence notes, expected counts, and last-practised freshness. After training, tap a kata to log a run-through. Record reps, self-rate sharpness from 1 to 5, and add an optional free-text instructor note. The readiness engine recalculates a weighted checklist of required kata freshness plus minimum run-throughs, updating your next-belt percentage on the ladder. Use the grading checklist screen to toggle syllabus items complete or pending with notes for exam day. Open practice history per kata to review past sessions, sharpness trends, and instructor notes—so you know what to polish before you step on the mat. A seeded demo track (karate-style ranks and sample kata) makes the ladder useful on first open. All tracks, sessions, and checklists stay on-device for true offline dojo use. No account required—just your forms, your progress, and your next belt.
