HBO's new standalone service will launch in April, the network announced on Monday. But you may not be able to get it on all your devices just yet.

HBO NOW, which for the first time will provide access to all of the cable channel's programming without an actual cable subscription, will be available on any computer, but will also launch exclusively on iOS devices. Customers can subscribe for $14.99 using the HBO NOW app on their iPhone, iPad or iPod touch, or directly on Apple TV. (HBO says it is still negotiating with other companies to make the service available on other devices in the future.)

"HBO NOW is the next phase of innovation at HBO," Richard Plepler, chairman and CEO, HBO, said. "With this new partnership, a natural evolution for the network, we have access to millions of Apple customers who are used to getting their favorite apps immediately. Now, they can do the same with an HBO subscription."

Added Eddy Cue, Apple's senior vice president of Internet Software and Services: "HBO NOW offers a new generation of HBO fans many of the best TV programs in the world without a cable or satellite subscription. Now, with the same simplicity as buying an app, customers can subscribe to HBO NOW and instantly start viewing their favorite HBO programs as they air - this is huge."
