Today I had the opportunity to try out iStopMotion ($9.99). This is by far the best app I have seen for creating stop motion movies. It is very intuitive and easy to use. I think that most people would be able to teach themselves quite easily. The one feature that makes this app worth the money is the onion skinning of the last photo taken. This semi-transparent view of the previous image allows the user to precisely place the objects being animated in respect to their previous position. (see below)
I’m looking forward to using this app with students. Below is the animation I created today.
