PlayWrite
Coaches' Brain develops free and open source software to draw basketball plays. PlayWrite is a desktop application for windows that allows coaches to draw basketball plays and export them to PDF. Coaches can save their plays to their documents and edit them later. Coaches may archive their opponents plays and reference them easily to achieve strategic dominance next time they face off. Furthermore, the software makes distributing copies to players through printing or PDF simple and easy. PlayWrite includes touch screen support and many other features which you can see in more detail on the updates page.
