tal of 30% of smartphone and tablet owners in the UK intend to bet on the 2014 World Cup with their device, according to a report launched today by app performance firm AppDynamics and Goldsmiths, University of London.

The average wager size on these devices is estimated to be £62.65.

Mobile could prove vital to bookies’ success as one third of people surveyed for the study said they would spend more money with an organisation that had a good mobile app.

Tom Levey, EMEA technical evangelist at AppDynamics, said: “Betting online on the World Cup is a high profile example of what happens every day on a monumental scale.

“Web and mobile apps now play a prominent role in people’s lives and are central to a huge, growing digital economy."

However smartphone users are characterised by high expectations and a willingness to switch apps; 82% have deleted an app because of poor performance.

Jyoti Bansal, founder and CEO, AppDynamics, said: “In so many ways, for so many businesses, success is now defined by software, as customers expect seamless performance and reliability from all digital services."

The total amount wagered online could top £500m, with twice as many people favouring websites over betting shops.

The research was conducted by surveying 1,000 UK and 1,000 US adults.
