Now users of Apple handheld devices have a way to hide Facebook use at work like everyone else does, thanks to the release of Facade Book.

To date, the most common types of tools for deceptive Facebook use at work were designed for computers and involved the mimicking of popular software, such as the Microsoft Excel spreadsheet, in the case of Excell Book, which is no longer available.

This application for the iPhone, iPod Touch, and iPad, displays Facebook content in an interface identical to the Apple operating system’s to-do lists and contacts, hiding the fact that the user of the device is on the social network.

Facade Book is available free-of-charge for a limited time, after which downloading the app will set users back 99 cents.
