Stupid As....s app

What is the sense of this app??? Not a navigator. Camera shows you what it see on to the iphone screen and a small map on the corner. You can just look out through the windshield with your own eyes like you are already doing. Stupid as it can get. People reviewing saying see potential. I see potential of deleting as soon as I post this review.
