If you own an Amazon Kindle Fire tablet and Fire TV streaming box, then you can access a handy new feature. Called Amazon Fling, it lets you beam whatever's on your phone or tablet – including video, audio and still images – to your TV screen.
It works just like Apple AirPlay or Google Chromecast.
You'll need an Amazon tablet (or Fire Phone, though we'd advise against that) and a Fire TV set-top box or Fire Stick dongle to use it.
Developers can also implement "two-way communication" between the corresponding devices, to make "engaging second-screen experiences".
This has great potential for looking up trivia during a TV show, say, or displaying secondary information like ammo and health during a video game.
The app Karaoke Party, for example, uses Fling to show song lyrics on the mobile device, and to send audio from its microphone to the TV. Rivet Radio, meanwhile, lets you listen on your mobile device with the option of sharing it with everyone by playing it through the TV.
Let's hope we see some cool new uses soon.
