Ripdev offers developers a third-party protection service that works to prevent piracy. The company says "With Kali Anti-Piracy your application is being wrapped in the additional layer of protection engineered by experts in Mac OS X and iPhone OS architectures, giving potential hackers much harder time in achieving the precious 'crack.'
