Sky subscribers are now able to watch films and Sky programming on the go, without having to be connected to the internet.
Sky's brand new service, Sky Go Extra, will allow subscribers to download and watch Sky content from across all of the provider's channels - including the latest releases on Sky Movies - wherever they want. Once the content has been downloaded onto a device, users can store the films and programmes for up to 30 days.
The service, which lets users register up to four internet-connected devices, costs an extra £5 on top of a Sky package and allows subscribers to download as much as their device can hold.
Sky's Managing Director of Sales and Marketing, Stephen van Rooyen, said the new service helps Sky to "deliver helpful and innovative ways for Sky customers to enjoy even more flexibility over when, where and how they enjoy Sky."
Sky already offers Sky Go, which allows subscribers to stream movies and programmes, and an On Demand TV service.
The BBC launched a similar app last year for iPlayer, which allows viewers to download programmes to tablets and smart phones. The free service allows users to download multiple programmes and keep them on their device for 30 days.
