One of my friends was one of the designers of this phone app, so I thought I would put in a plug for it. It is called "Coache's Eye" and allows you to video from your smart phone and then play back the video frame by frame and also has illustrative tools to "draw" on the video to help coach from the clip. It is a great tool for an instructor to be able to go frame by frame and show someone their motion and give feedback that they can see to make the changes needed.
