There is also w version for Chrome.
Honestly, I wouldn't use an app. It seems like you're solving an already solved problem. I can type pretty much any film/show into Google and it'll give me all the cast, links at the top to RT and IMDB, along with a score for each etc etc. There's literally bar at the bottom of my phone screen to type into, with a microphone if I don't want to type.
But an app on my iOS device is not the solution. I’m not going to hold up my phone and have it scan the thing on my TV screen across the room, then rinse and repeat that action for every single thing we might watch.
But Amazon Prime is stuffed to the gills with shitty movies (and they only display the IMDB rating for some of them, not sure what the algorithm for that is), and looking them up all the time takes too much time :(
I think you misspelled Android...
