This is a great app – Vernier Video Physics Review

I am a physics teacher, and this app is amazing. The best way to show it in the classroom is with (surprise) vernier's logger pro software. Record the video on the iphone and then send it to your computer. Then use logger pro on your computer and show it on the LCD. I am even able to avoid mac/pc issues when I use my school's pc's. The controls are a bit touchy when using the analysis tools on the iphone, but it just takes getting used to it.
