Roku announced in a press release that the Apple TV app would be available on its streaming devices starting today:

For the first time ever, Roku users can add the Apple TV app via the Roku Channel Store to discover and watch movies, TV shows and more, including accessing their iTunes video library and subscribing to Apple TV channels directly on Roku devices. Starting November 1, Apple TV+, Apple’s home for all-original shows and movies from the world’s greatest storytellers, will be available on the Apple TV app on the Roku platform.

Like the TV app on Samsung smart TV sets, the Roku version of the app offers access to all iTunes movie and TV show content, as well as all Apple TV channels options, such as HBO, CBS All-Access, and soon Apple TV+. However, content from non-channels like Hulu or Amazon Prime Video, which are accessible on iOS and tvOS devices, will not be present on the Roku version of the TV app because it lacks third-party app integrations. Moving forward though, I expect that all of Apple’s new content partners with the TV app will be full-on channels rather than legacy app integrations.

Earlier this year Apple announced that the TV app would also be arriving on Amazon Fire TV devices and TV sets from more manufacturers, so as we get closer to the November 1 launch of Apple TV+, I expect we’ll see those other vendors all follow Roku’s lead.
