If you want to experience refocusing a picture after you've made the exposure, take a look at FocusTwist, available for $1.99 in the iTunes App Store.
Once you've made an exposure, as explained in the graphic here, you can tap on different areas of the image do determine where the focus should be set. It's an engaging way to experience Lytro-like refocusing with a device you already have.
