The 'ultimate rugby' app is the best by a good margin. Has all international and domestic rugby matches with kick off times and live scores once the match kicks off. All tier one matches also have live text commentary. Player profiles with stats and appearances. The ability to mark teams, players, leagues and tournaments as favourites so you can get notified when they're about to kick off. News aggregation and daily news roundups on there too.
They do and it's a good app, although it has a few little things that irritate me.
