The app allows customers to browse and buy from the independent merchant’s new-look digital catalogue.
They can also read the stories behind the bottles and access exclusive offers in a format specifically designed for the tablet.
Managing director Glenn Caton said: “It’s great to see the uplift in mobile and online sales as it shows that our customers are really responding well to the development of our digital offering.
“However, we are not neglecting those who prefer to buy in-person or on the phone – we bucked the downward trend for high street retailers with our shops achieving an 11% year-on-year revenue uplift in December 2012.
“People can buy from us whichever way is most convenient for them – whether it’s online, on the go, on the phone or in person. That’s not something many merchants can offer and the figures show that our customers really appreciate this multi-platform approach.”
In December 2012, wine orders from smartphones also grew 140% at Laithwaite’s.
The launch of the iPad app follows the redesign of its website and the launch of its mobile app last year.
That app which allows customers to browse and buy, as well as find bottles by photographing the label.
