Its not a scam, but not worth your energry – Screen Mirror for Samsung TV Review

It does work, but the application is very limited. It has you use the iphone screen record feature to help trick the iphone into casting to a smart tv device. its clever, but it also simultaneously clogs your phone with sometimes length videos of your screen recorded broadcast. just buy an apple tv on amazon like I just did.
