Leap Card users in Dublin, Cork, Galway, Limerick and Waterford will be glad to hear that they can now top up their Leap Cards using just their smartphones. 

The National Transport Authority's Leap Top-Up app, which was launched yesterday, allows users to instantly top up their Leap Card, check their balance and collect tickets before hopping on public transport. 

The process is very easy and is outlined in full in the video below, however there is one catch; the app is currently only available on Android devices running Android 4.4 KitKit and later, so iPhones users and those with older Android devices will need to wait for a little while or upgrade to use this handy app.
