Duh?

Reviews I read must be from idiots. "DIGITAL" zoom, means it zooms in on the photographed image, "OPTICAL" zoom means the actually lens length is increased. There will be no app that will magically increase the length of your lens in your iPhone. That is dumb. For what it says its supposed to do, it works. BUT...
Sometimes ads have no close button or "x", even after waiting 15-30 seconds. (If any app allows 1-minute ads, they will not be privy to my expert use and reviews - aka - they can go pluck themselves.)
