I’m looking for a great client that is usable across Android TV, iOS, Fire TV, Windows, and Roku (if possible) with an interface that’s easy enough that my grandmother could use it. Is such a good client out there? I’m willing to pay a little money per device need be if the support is great and the client won’t be going anywhere anytime soon. Thanks!
My vote is TiviMate, hands down. It is still having features added, and at this point there are only a few that I would say are "missing" but otherwise it absolutely gives you the experience you would expect from a TV app.
