Harrods, the Kinghtsbridge-based department store, has launched an official iOS app.

Free to download from the App Store, the Harrods app is compatible with iPhone, iPod touch and iPad and requires iOS 4.0 or later.

It contains news about the brands stocked in London's most famous department store as well as a map of each of Harrod's seven floors.

In-store events can be added to iCal, and an audio tour of points of interest in the store is available as well.

Some users of the iPhone 3G and iPhone 3GS have reported problems with the app crashing, but Harrods has promised a fix for the problem soon.
