I know its not official, by Auntie Player (iPlayer App) is simply brilliant - the best iPlayer interface I've used on anything. It only takes a few minutes to load as long as you have a Mac and USB-C cable.Well except it's still missing BBC iPlayer, BBC Sport, All4, ITV Player, Demand 5, Animax, Blinkbox, Spotify ... Not to mention a modern looking Now TV app which isn't a pile of festering sewage.
But hey, Amazon is a huge win all the same.
