App bookings now making up 11 per cent of all business.
London-based taxi firm Addison Lee expects to rake in a whopping £20m in revenue in 2011 from customers booking cars through the company's iPhone app.
The firm received 75,000 bookings through the iPhone app in the month of May alone, which brought in £1.4m in revenue, which was a record month since the launch back in January 2010.
The free app, which has been used by 43,000 people to book taxis now and now accounts for a sizable 11 per cent of its business, also has a version for Android and BlackBerry soon to arrive in their respective app stores.
The app allows you to easily book cash or card taxis and will give you a quote before you confirm. You can also just enter your address and the nearest free cab will be sent directly to you, along with the driver's contact details.
"Most customers now use smart phones with GPS and we've seen a huge surge in demand for mobile app bookings," says IT director Peter Ingram.
"We've recently been testing our Blackberry and Android apps and getting very positive feedback from customers via Twitter, so we're confident both new versions of the iPhone app will be a big success."
