A new transport app is replacing two others, which are to be stood down from next week.
The TFI Live App is an amalgamation the Real Time Ireland and Journey Planner apps.
Transport for Ireland has said the two older apps will "no longer be supported" from February 22nd.
This means they will be removed from the app stores and no longer be available for download.
The new app is going live from Friday.
It has a fully integrated trip planner, and shows real-time departure/arrival information for Bus Éireann, Dublin Bus, Go Ahead Ireland, Luas and Iarnród Éireann.

"The backend systems supporting the new TFI App are also newer and more modern," it said.
A spokesperson said this is about bringing the two apps into one place, and there will be some additional features.
This will include information on unplanned bus diversions along a route, and improved coverage of walking routes.
The apps will also be easier to maintain in this new set-up, the spokesperson said.

Asked about criticism of some unreliable information in the apps, the spokesperson said they are working on this but it will be a 'longer-term' project.
Users will also have re-input existing preferences, such as bus stop numbers, into the new app.
TFI said this is because this is an entirely new app.
"All customers will have to download and install TFI Live, as it will not automatically upgrade due to controls in place on the app stores that are outside of our control," the authority said.
