Actual correcting works. Cropping lines act kind of erratic, unstable on my Seven/Plus. By saving you put the image in another extra iOS folder; ocassionally it crops your crop during the export (by it's own means) Apropos: Don't expect export into cam roll. I wasn't even smart enough to delete the auto-created image trash versions within their special folder.
It's a great tool, but unfortunately very hard to use on an iPad Pro 12,9" as it does't display it correctly.
Why can't I change the horizontal and vertical correction at the same time? I can either change the one or the other... Until this is fixed, 1 star.
