The $15 per month standalone streaming service is available now on Amazon Fire tablets, and will land on Android phones and tablets later today.

Although HBO Now is only just opening up to more platforms, analysts have already predicted the service has attracted a substantial amount of subscribers.

Three months ago, HBO made its programming available to consumers without a cable subscription, selling a streaming service called HBO Now on Apple devices. So now you can also watch on devices like the Amazon Fire TV and Fire TV Stick, current-generation Roku players, Roku TV models, Xbox One, and Android devices, as well as iOS devices, Macs, and PCs. If you download the app to your phone or tablet, HBO is tossing in a free 30-day introductory trial of HBO Now that can be accessed through Google Play or the Amazon Appstore.

With HBO Now no longer exclusive to Apple devices such as the iPhone, iPad and Apple TV after its April 7 launch, Android users can now catch up on HBO content like Game of Thrones or True Detective on-the-go. It lets you access all of HBO (TV series, movies, documentaries, sports programs, plus comedy and music specials) for $14.99 per month.

“Amazon has cultivated an incredibly vast and savvy base of customers that we’re excited to provide with unlimited access to all of HBO through HBO NOW“, said Bernadette Aulestia, Executive Vice President, Global Distribution Operations, HBO.

The number of households in the United States that subscribe to high speed internet but don’t pay for TV grew to more than 10.5 million past year, growing 16 percent over the same period in 2012, according to the research firm SNL Kagan. Selection for Amazon Fire TV has increased by over 700 channels, apps, and games since February, and almost 2,000 titles are now available, with HBO NOW coming soon.
