I use two apps and neither of them are the official app.
My main app is GRTransit. It gives realtime info, has a favourites list, shows all bus times, and can also find all nearby stops.
The other app I use, as of recently, is BusStop. I like this one because you can rename stops on your favourites list. With the other app, I'd have to memorize stop numbers if I have multiple stops from the same route on my favourites list but with this one it's just really easy to discern stops at a glance.
I'm on Android--I have no idea if either of these are available on iOS.
