Luxury department store Harrods has launched a GPS-assisted interactive iPhone app.

Following a sneak preview on Twitter last month, the app will be available from iTunes tomorrow.

It aims to help shoppers navigate around the store through an interactive location guide. There is also a news and events page, a history of the store and 3D visualisation.

Harrods store image director, Mark Briggs, said: “The Harrods iPhone App is an exciting new way for us to further engage with our customers. We are continuously aiming to offer our customers the optimum level of service through use of new technology. With its useful tools and services, the Harrods App is set to become a vital part of the shopping experience at the store.”
