Dundalk taxi drivers have started to use the Hailo taxi app in the last few weeks.
Hailo is a smartphone app that allows users to hail a taxi using just their phone, and without calling a taxi service.
The user places a pin on an on-screen map to guide the driver, or allows the phone to use their GPS co-ordinates.
There are no extra charges with the app, compared with other taxi services which can include a call-out charge, and journeys can be paid for using card.
All drivers are already licensed drivers.
The company says over four million trips have been made using Hailo in Ireland since the app first launched here in 2012, and was rolled out to Dublin, Cork, Galway and Limerick.
Taxis using the service are now available in Ashbourne, Bray, Greystones, Balbriggan, Celbridge, Navan, Trim, Athlone, Leixlip, Mullingar, Maynooth, Drogheda, Sligo, Ennis and, of course, Dundalk.
The company intends to roll the service out to Arklow, Letterkenny, Longford, Roscommon, Carrick-on-Shannon, Clonmel, Thurles, Ballina, Castlebar and Westport in the coming weeks.
It is also available in cities like New York, Toronto, and Barcelona.
The app has been downloaded more than 400,000 times in Ireland.
