Now that I’m back with an iPhone, I find I have a usable mobile plat­form for doing cool stuff. I started using video with my stu­dents in the last few months as I recov­ered from elbow injuries, and found it to be quite useful.

In par­tic­u­lar, I like to take very focused short bits of video to help stu­dents see what I see in their technique.

Turns out there’s an awe­some iPhone app for doing just this… this app will take video, let you anno­tate it graph­i­cally, and then share it with the stu­dents. You can even slow down or speed up the video to make your point. It’s really cool.

If you coach, mar­tial arts or any­thing, you’d be silly not to try Coach’s Eye. It’s quite afford­able at $4.99 too!

My friend George tried it out and posted a video so you can see how it works.
