HBO's new standalone streaming service will launch next month with Apple as its exclusive launch partner.

HBO CEO Richard Plepler made the announcement during Monday's Apple event in San Francisco. HBO NOW will debut in April for $14.99, and customers can subscribe using the HBO NOW app on an iPhone, iPad, iPod touch, and Apple TV. Once you're signed up, you can also watch on PCs via HBONOW.com.

HBO will offer a 30-day free trial period for those who sign up in April. Those who sign up will get it in time for the April 12 premiere of Games of Thrones, Plepler said, before debuting a brand-new trailer for the next season of the fantasy drama.

For those who don't have an Apple TV, CEO Tim Cook announced that its set-top box will get a price drop, from $99 to $69. He did not announce any upgrades for the device, however, which last saw a makeover in 2012.

For those on other platforms, HBO said it "continues to be in discussions with its existing network of distributors and new digital partners to offer HBO NOW."

HBO said HBO NOW will be similar to HBO GO, which offers Internet-based access to the company's full lineup of content, from original series and documentaries to movies and sports programming.

HBO first announced plans to launch a standalone streaming service in October. "We will work with our current partners. And, we will explore models with new partners," Richard Plepler said at the time. "All in, there are 80 million homes that do not have HBO and we will use all means at our disposal to go after them."
