Ignore the negativity.
This is a really great app no matter what others may say. Since Picnik closed, Ive been looking for an alternative way to edit photos; mainly in the teeth department. It works well for me. Yes, if you whiten to the maxium it appears a little light blueish, but if you only up it one or two notches it looks completely fine.
