LANDSCAPE!!! Face detection only works well when phone is in a landscape orientation. App authors should put this in the description, this would probably stop some of the 1 star reviews.
Not that great There are many false positive. A rack of books at the shelf is regards as a face.
Useless Viewing a friend's face and the app is displaying green rects around him. Maybe they're ghosts!
As a developer view, its great
Worst app. Doesn't open properly
It won't take the green box out of one face even when I shake it too hard!
Application updated with OpenCV 2.4.3 release.
