Basketball App?

I have been looking for a website or app that I can create plays on, and I was wondering what some of you guys use. Any input would be helpful. I feel that some kids need to actually do it and some learn better by seeing it. I am just trying to cover all aspects of how they may learn or understand the plays.

I'll email you info on what we use. Thanks.

I'd love to hear what you use as well. Thank you!
Mike
