This app is currently with Apple awaiting approval to the App Store. It has been developed by Tinrocket LLC the developers of the very popular iPhone photography app, Percolator. Unlike Percolator which took the combined efforts of several people and many months to develop, Popsicolor has been developed entirely by John Balestrieri, who heads up Tinrocket in only 7 days.
This app should be approved in a week or so. We managed to get hold of a few screen shots and output images to give you an idea of what's coming soon.
