Draw what happens, not frames
A play is a list of things players do. You draw those; the timing, the ball and the animation follow from them.

Drag from a player
Line paint lays itself down behind the pointer. On release a chip lands at the arrowhead with the action the app guessed; one tap changes it. Every tool also has a single key.
Standard notation
Solid line for a cut, dashed for a pass, a wave for a dribble, a T-bar for a screen, two ticks for a handoff. Numbered offense 1–5, X for defenders.
Phases, the way you teach
Each phase starts where the last one ended. Actions in a phase run together, after one another, or with a delay you set. Mark an action as an option and it is drawn but not run.
A camera, not a second editor
Top, isometric, sideline and baseline are views of the same drawing. Orbit with a drag, zoom with the wheel or a pinch. Nothing about editing changes when the court tilts.
Nothing is lost
Autosave, undo everywhere, JSON export and import. Free plays live in your browser; on Coach they sync to your account.
Features
Simulated defense
Five defenders take their positions from the settings you choose and react to the offense you drew. Change one setting and run the same play again.
Video export
If you post plays, the diagram is the content. Export it in the shape of the platform, rendered frame by frame so it never stutters.
Quizzes
A play a player has answered questions about is a play you do not have to walk through twice.
Teams & playbooks
A playbook is one team’s plays, in the order you teach them.
