Try SnappyCam

For 99 cents, I bought yet another iPhone application, SnappyCam.  It's an app that allows you to take a very rapid series of photos with your phone.  It is incredibly easy to use and works great for action series.

I was playing golf with Chad yesterday and he SnappyCammed me so I could see my swing.  Between my backswing and my finish, there are about 30 shots. From what I read, an iPhone 5 will take shots even faster than my 4S.

If you have any fast action stuff you want to capture, this is a great way to spend a buck.
