Apple has AirPlay, Google has Cast and now Amazon has Fling.
Once the content is on the larger screen, those users will have the choice of controlling playback via their mobile device or the Fire TV remote.
A couple of developers are already making use to the SDK, with the Karaoke Party app sending both the lyrics and the singer’s audio to the TV via a smartphone’s built-in mic.
A second app, Rivet Radio, has been adapted to allow audio news content to be sent to the Fire TV, allowing the whole family to listen in.

Amazon says Fling is able to “leverage two-way communication between Amazon Fire TV and mobile apps to create engaging second screen experiences.”
This opens the possibility for iOS and Android owners to use their mobile device to interact with apps already built into the Fire TV experience.
Amazon also pointed out how simple it would be for devs already using Google Cast to add Fling compatibility to their apps. To aid the transition the company is also providing support documentation.
