The wedding of Prince William and Kate Middleton will have its very own app in what has got to make it one of the geekiest wedding accessories ever - well unless you count a Royal Wedding GE fridge.

According to details sent to us by the Royal Collection - that’s the division of the Royal household that deals with these kinds of things - the new Royal Wedding application will tell the story of seven royal nuptials from Queen Victoria and Prince Albert in 1840, to the Prince of Wales and the Duchess of Cornwall in 2005.

“Apps enable us to place works from the Royal Collection in the hands of a worldwide audience. It is fitting and exciting that the first Royal Collection App will share the stories of past royal weddings and offer a wealth of historical context for the ceremony on 29 April,” said Jemima Rellie, director of publishing and new media for the Royal Collection.

The Royal Weddings app, which will be available in eight languages, is the first in a series of Royal Collection Apps to be launched this year.  Forthcoming subjects include Changing the Guard and State Banquets.

The royal weddings app is priced at £1.79 and will be available to download for Apple and Android phones from 18 April.

Highlights of the Royal Weddings app include:

- The sapphire and diamond brooch given to Queen Victoria by Prince Albert on the day of their wedding.

- A watercolour sketch by Queen Victoria of her bridesmaids’ dresses.

- A sketch of Queen Victoria’s wedding cake, which is said to have measured over 9 feet (3 metres) in circumference and weighed over 300lbs (140kg).

- A photograph of the roses given to Prince Edward by his fiancée Princess Alexandra on the day of their engagement, 9 September 1862. The Prince carefully pressed the roses and kept them with a note written in his own hand as a keepsake.

- Her Majesty The Queen’s wedding dress, designed by Norman Hartnell.

But the official app isn't the only royal wedding app on the block, numerous developers, and media outlets are getting in on the action, with The Mirror amongst others launching an app to celebrate the big day on the 29 April.
