The are a few Polaroid apps for the iPhone, and I have had a hard time finding good comparisons of them, so here are three photos created using the three most popular apps using the same original image.

ShakeItPhoto uses a square frame, Polarize and ShakeIt use a frame that looks more like the original Polaroid format if I remember correctly (I have never actually owned a Polaroid camera).

The best experience award goes to ShakeItPhoto. The best value award goes to Polarize (free) and ShakeIt has the nicest frame. Only Polarize allows you to add a text note to the image. I think I will be using ShakeItPhoto mostly.

The original used to make the polaroids in the three apps can be seen here http://www.flickr.com/photos/finurlig/4174564256/
