For Sensei
Keiko Spinner
Build lessons in one tap. Drills, segments, and class outlines.
What it does
組
Assemble the class
Stack warm-up, kihon, kata and kumite into one clean outline.
時
Time each segment
Give every block a length. The class keeps its own clock.
引
Reuse what worked
Save an outline and bring it back next week in a single tap.
Walk onto the floor with the lesson already made.
Plan the hour before you tie your belt, then teach from a glance — not from a notebook you left at home.
