Ahead of the arrival of Apple TV+, the brand-new Apple TV app is launching on Roku devices, starting today. The app currently allows Apple customers to access their iTunes video library and subscribe to Apple TV channels directly from Roku devices. And, on November 1, it will also be home to the Apple TV+ streaming service, featuring Apple’s own original programming like The Morning Show, See, Dickinson, For All Mankind, Truth be Told, and others.

The new app will authenticate users with their Apple ID, so they can access their purchased content, get personalized recommendations, subscribe to paid channels (e.g. HBO, Starz, Showtime, etc.), and buy and rent over 100,000 movies and TV shows from iTunes. Additionally, Roku users will soon be able to subscribe to Apple TV+ right in the app for $4.99 per month.
