I am really enjoying Polarize for the iPhone. It adds a fun ‘Polaroid’ style border to photos taken with the iPhone camera. You can add a text note to the tab on the bottom of the Polaroid photo, the same as you could a real one.
You will find the app HERE.
My only wish, is that the app didn’t reduce the resolution of the photo as part of the process. This example is the actual size saved by the app.
