WarnerMedia announced last week that its new HBO Max streaming service will launch in May for $15 per month. Now, WarnerMedia has announced that it is teaming up with Apple on the launch to ensure a seamless experience for iPhone, iPad, Mac, and Apple TV users.

According to the announcement, HBO Max will be available through and fully integrated with Apple’s TV app at launch on May 27. Through this agreement, customers who are billed through the App Store or through Apple TV Channels for HBO Now will be “upgraded automatically to HBO Max at no additional charge.”

If you’re not an existing HBO Max customer, you’ll be able to sign up through Apple’s platforms for $14.99 per month. Presumably, this includes in-app purchasing as well as accessing HBO Max through Apple TV Channels, but exact details are somewhat unclear for now.

As expected, there will also be a new HBO Max application that’s available for the fourth-generation Apple TV as well as iPhone and iPad. Those using an older Apple TV model will have to use AirPlay to stream content from their iPhone to the TV. This is unsurprising given HBO’s other recent announcements regarding support for the 3rd-gen Apple TV.

The standalone HBO Max app will fully integrate with Apple’s TV app as well.
