If you have a Samsung Tizen Smart TV with a model after 2015 there's a put.io app for it! You can search for "put.io" in the Tizen app store and start using it.
You can also use the same interface from other smart TV's by visiting https://tv.put.io from the TV's browser.
P.S. Good news! We are working on a new Samsung TV app and with this we aim to make the streaming experience better for you guys!
