Amazon announced that starting Thursday, Apple's TV app is now available for download to Amazon Fire TV devices, namely the newest Fire TV streaming stick and the Fire TV Stick 4K. Amazon says the app is coming soon to more Fire TV devices, including older Fire TV streamers, the Fire TV Cube, Fire TV Edition televisions and the Nebula Fire TV Edition sound bar.

The app is the exclusive home for the Apple TV Plus service, due to go live on Nov. 1. The service is a Netflix rival that will launch with nine confirmed titles, including a drama called The Morning Show, starring Reese Witherspoon and Jennifer Aniston, the post-apocalyptic thriller See starring Jason Momoa, and a comedy about poet Emily Dickinson. It costs $4.99 (£4.99, AU$7.99) a month, but buyers of new and refurbished Apple devices will get a year of access for free.

Amazon joins Roku, which added the Apple TV app last week, and Apple's own Apple TV media streamers, iPhones, iPads and Mac computers, in offering the Apple TV app. The app is also available on Samsung smart TVs, and is coming "in the future" to TVs from Vizio, Sony and LG, according to Apple.

Beyond access to Apple TV Plus, the app also lets Fire TV owners watch iTunes TV shows and movies they already purchased. Unlike with Roku and other devices, however, Fire TV doesn't offer the ability to buy or rent iTunes content from directly within the Apple TV app; you have to make iTunes purchases elsewhere.

The Apple TV app on Fire TV does offer Apple TV Channels, which lets you subscribe to and watch services like HBO, Showtime and Starz from within the TV app, without having to download those individual apps. Apple TV Channels is very similar to Amazon's own Prime TV Channels feature.

Apple's app works with Fire TV's built-in Alexa voice assistant to allow voice searches for particular shows, for example, "Alexa, play Dickinson." Alexa commands can also find and open the TV app, but don't work for finding iTunes content.

Similar to the Roku version, the Fire TV offers no AirPlay support for streaming content off of iPhones, iPads and Macs. Smart TVs from Samsung, Vizio, Sony and LG, as well as the Apple TV box itself, do work with AirPlay.

Amazon's representative also confirmed to CNET that "Dolby Vision and Dolby Atmos will not be supported at launch, but we're working with Apple to add additional support for this type of content in the future."
