Sport on the move is proving a real winner for Betfair

Online gambling firm Betfair said its investment in betting-on-the-move was paying off as it revealed the number of wagers placed on devices such as iPhones and iPads had doubled.

Some 7.4 million bets were placed with Betfair on mobile devices in the three months to the end of July, twice the number in the same period last year, while a third of all wagers with the company are now placed on a mobile product.

The group, which allows punters to set their own odds and bet against one another, said it upgraded its mobile services in the quarter, including improved live score updates and faster response times.

Betfair, which floated last October, saw total revenues drop 7 per cent to £80.8m in the period, but this was compared to a strong quarter last year boosted by the World Cup.

The improvements made to mobile services, which have also included a new iPad app, led to an increase in the amount of time spent on mobile betting and 78 per cent growth in mobile revenues to £4.2m.

The company, which has nearly four million registered users, enjoyed its best ever Royal Ascot, Wimbledon and Open golf championships.
