Miguel Sanchez-Grice, creator of the iCombat app (a remake of the old Atari game), sent us these stats on piracy of his app after writing a blog post about the same thing, and I find them fascinating. Instead of building DRM into his app, he just detected if the player was using a copy that wasn’t from the App Store, and then forwarded them onto a web page that he could track. It seems like he equates unique visitors to his Pinch Media site as users (though he doesn’t go into detail about exactly where those “Pinch Media New Uniques” numbers come from), and then subtracts legit app sales from those numbers to get the number of pirates. And while he says the numbers are lower than he expected, they seem pretty high to me: there is a substantial number of people out there using cracked apps.
