Black Tablet

Apps for your iPhone, iPad and iPod Touch



This futuristic, yet retro technology allows you to break the secret codes supplied in the 1960s Sci-Fi comic "TV Century 21". Not only that, but you can encode your own messages to surprise your friends on Twitter.

The original issue of the comic on January 23rd 1965 came with a functionally identical code-breaker but, almost 50 years later they are a rare beast indeed and possibly chewed and mouldy as they were made of thin card and paper. So, if you have some old copies of the magazine and you've been yearning to know what those secret messages at the foot of the pages were then this is just the app you've been looking for!
