Having used the Arriva live tracking app on and off for a while now, Black Friday and its inevitable delays prompted use of the GNE app for the first time yesterday.
Whilst the display and set up is similar to the ones used by train operators in showing the movement between specific stops, I much prefer the live tracking seen on the ANE version.

I could tell my GNE bus was on its way, but couldn't identify if it was moving, stuck at a stop etc. It was a case of 'it's passed X, but not sure where it is in relation to Y'.

However, when I tested it out on a service running in pairs, the app didn't translate that. It just said when A bus was due. Not that there were two.

Still useful, compared to not having a clue if it was running or not.
