If you’re a basketball coach, player, or just a devoted fan, you can now use your iPad as a playbook. Use the PlaybookBball app from Daren to create step-by-step plays on a court drawn to scale. Select high school, NCAA, FIBA (Oct. 2010 rules), or NBA courts; select the number of players per team and their positions, and choose to show or hide opponents. You can watch animations of your plays and email a PDF of your play to your team. You can even include notes in your plan for later reference, or copy an existing play to try out modifications. There are some videos at YouTube demonstrating features of PlaybookBball. The PlaybookBball app (iPad only) is $4.99 at the iTunes store.
