Trakt for iOS
Works on iPhone and iPad.
I found this show greatly appreciated, good story and visuals despite some CGIs throughout the show, very enjoyable and quite worth watching if you like ancient history, different from the others show recently.
What started really well, plunged down completely throughout the following seasons. Shame as the idea was badly executed. I have watched it throughout hoping it will get better but unfortunately except for a few tiny moments, the series as a whole turned out to be a bit daft and boring and very predictable
