Domino's Pizza has seen a doubling of orders taken on mobile devices during 2012, the company has announced.
The takeaway delivery company said that for the 53 weeks ending December 30 a total of 19.7% of online orders were made through smartphones and tablets.
The figure was almost a doubling of mobile ordering from a year earlier, when 10.1% were made via those devices.
Domino's said 55.7% of all UK sales in 2012 were made online, up from 44.3% in 2011.
It sold 61 million pizzas - up from 56 million a year earlier and opened a record 69 stores.
Although it also closed two stores, it now operates 805 stores in four countries and created 1,500 new jobs.
It expects to employ around the same number of new staff this year.
The statistics were announced as it released its annual preliminary results, showing like-for-like sales up 5% in its 612 mature UK stores, with UK operating profit up 15.7% to £45.2m.
Results for the group, which operates stores in the UK, Ireland (OTC BB: IRLD - news) , Switzerland and Germany, showed company-wide sales increasing by 12.8% to £598.6m, with record pre-tax profit of £46.7m, up 10.8%.
Chief executive Lance Batchelor said: "Despite a very challenging economic environment, our people and our franchisees have delivered another impressive set of results.
"This performance further demonstrates the resilience of the Domino's Pizza home delivery market."
But the company admitted that snowfall in January has significantly affected its new year business, with more than 60% hit by closures.
Mr Batchelor said: "Clearly the recent spell of poor weather and widespread snow in week three and week four has had an adverse impact on trading.
"During these two weeks, we had a total of 498 stores closed at some point - almost two-thirds of our UK store network was impacted."
