This app is pretty damn good. Makes replaying games so easy from previous rounds and offers live streaming of games if you have a foxtel account which is good if you are on the run. The feel of the app is pretty good as well.
I think I read it was coming to android devices but slower to come out due to so many different tablets and making sure the navigation work seamlessly on all.
Unfortunately it is not unmetered yet. There is the NRL Telstra Live app that is unmetered on the iPhone but it costs $90 a year but you don't need foxtel.
