Plot out all your flat-track strategy on your iPad: an interactive, animated whiteboard for Roller Derby plays.

- Keyframe animation: set the skaters in their appropriate locations at specific times, and it will animate between them (skating along the course)
- Customize team colors (primary, accent colors, and number text colors)
- WFTDA specified track layout dimensions
- Automatically calculates pack and engagement zones (using official WFTDA "box" method to determine 10' proximity)
- Includes a whiteboard to make annotations on the track, as well as textual detail (with special "cleanup" logic to make easy straight or circle players)
- Supports unlimited number of documents (including being able to duplicate the current document, making it easy to diagram out multiple scenarios)
- Connects to external monitors to use with projector/large screen
- Plays can be emailed to another Derby Playbook iPad user, the current frame can grabbed as an image (to paste into another app), or all the keyframes can be emailed as a PDF or printed
- Configurable of penalty box placements, track background, skater icon styles/sizes
- Undo/redo
