SCAM
This app does the exact same thing that IOS does. It does not stretch photos to fit your screen. Square to rectangle for example. All it does is zoom in on the picture. Total rip off and a blatant lie. I will be contacting apple support for a refund, and asking for this app to be removed on the basis of false advertising. DO NOT WASTE YOUR MONEY.
