The PriceRunner application is now free to download via a text shortcode, or from the Vodafone and Vodafone Live!, the multimedia portal.
Shoppers will be able to search for a specific product on their mobile phone, and the application will automatically compare prices, product specifications and retailers.
Gary Goodman, marketing director at PriceRunner.co.uk, has responsibility for launching the mobile version and is hoping to tap into a new audience, driving more traffic to the site.
Goodman said: "Our mobile application is a natural extension of our website, and will mean consumers can access our price comparison service wherever and whenever they wish, thereby giving them the confidence to know they are getting a good deal when making a purchase."
Al Russell, head of content for Vodafone UK, said: "We're very pleased to be working with PriceRunner and to be including their service in our range of iconic internet brands on Vodafone live!.
"We believe it will add real value to our customers who are looking for a good deal and want to compare prices on the move."
