Ireland with TFI Live and TFI Go apps for busses is another level of hell.
You need to use Live to find the route and times and it is buggy as hell. Then every person in your party needs their own phone and copy of the Go app (including children) to buy tickets. You also need to register accounts for each phone (no guest buying) and card details. Oh and they sometimes log you out.
In Dublin using Leap cards was a lot easier but you have to get the Leap cards and make sure you maximise value.
