Red Eyes removal does not work well on iphone 4 photos

I bought this app mainly because the red eyes removal tool. But it does not work very well on photos taken by iphone 4 with flash enabled. Some people get eyes very bright. Not only red. Until now there are no app that works well to correct this problem. It would be great if this feature was enhanced in this app.
