Can K9 keep porn off your kid's iPad or iPhone?

K9 Web Protection Browser for iOS is a free family-safe Web browser app for iPads, iPhones and web-enabled iPod Touch devices which promises to provide "immediate and highly accurate protection from content that is not appropriate for young children" which includes pornography, hate/violence, illegal drugs and gambling as well as basic phishing and malware protection for good measure. But it's what it doesn't do that disappoints, namely allow parents to configure what their kids can or cannot access.
