Not sure if app for tv or roku I use it on a shield, Apple TV, fire stick and my iPad all from one aerial and across lan it works great,Can it run through Plex or LG WebOS or Roku? I am trying to find a solution for humping Freeview around the house via IP to TV's.
With my ipad I can watch anywhere in world
Currently in Kos and have watched a few shows in evening which were recorded on my home server
So yes costs 8 dollars a month but for me well worth it
They have a pretty good forum so might be worth looking on there for more info
