More than 110,000 Dubliners have signed up for the new smart phone Hailo taxi app, which now has the biggest group of taxi drivers in the city.
The success of the app has prompted the company to plan for expansion to Cork, Limerick and Galway before the end of the year.
The new service provides a photograph and the first name and taxi number of their driver before he arrives at your door.
The service calls on any Hailo taxi in the immediate vicinity, uses sat-nav to pick up clients and allows them to pay by cash or credit card without any extra fee.
It boasts an average pick-up time of four and a half minutes, does not charge a call-out fee and allows five minutes free waiting time.
Says Rob Cumiskey of Hailo's Dublin office: "It's gone incredibly well. Dublin was the second city to bring in Hailo after London and we are really, really happy with the feedback."
The service has been joined by 3,700 registered taxi drivers in the city, which is one of five across the world current using the app including London, Toronto, Chicago and Boston.
It is also being rolled out in New York, Tokyo, Madrid and Barcelona with plans for further expansion.
Founded by three London Black Cab drivers and three internet entrepreneurs, Hailo is available as a free download from the iTunes App Store and Google Play.
