Works fine but needs more fine tuning.

It works well for me but I wish there was a way to save corrected picture right next to the original. Or better yet replace it entirely. Currently corrected pictures are saved as if they were new pics taken at the end of the camera roll.
Also, app color scheme is rather unappealing, it would be great if it matched closer overall Apple esthetic.
