Useless.
I think the app only makes the photos worse. Not only it changes the geometry of faces but it also changes the colour balance so that the picture looks just unreal.
Sorry guys, but this app is nothing special but a set of selected filters which in rare cases do their job, but again only 1/5 of the photos look good.
The tests were made with different photos takes in different weather and light conditions - the result is just the same.
