Disappointing.
I purchased this app, despite having my suspicions as to the method. My suspicions were correct...the method used to employ this effect can be quite noisy, and somewhat transparent. While the tutorial suggests performing in an environment with enough "ambient noise" so as to disguise the sound of the gimmick being used, I dont generally find myself in such a noisy location ! As almost everybody carries a smartphone with them nowadays, I tend to think most spectators will quickly clue-in, as to how this effect is done.
