Showtime’s iOS app has been updated and now will allow users of the Showtime Anytime app to view live programming from both the network’s East and West Coast feeds. Before this update, users could only view on-demand streaming of Showtime series like Dexter, movies and its XXX nighttime movies. This update will let you watch Showtime programming as it is fed to customers on both coasts. So you can be among the first to see it.
You just have to verify your current subscription with Showtime through the cable operator. Current operators that are supported with the app include AT&T U-Verse, Comcast XFINITY, DIRECTV, Optimum and Verizon FiOS. If you are a customer of one of those cable operators and own an Apple iPhone or Apple iPad, you are good to go.
It’s nice to be able to watch stuff at the same time that the episode is debuting on television. This update also fixes some bugs while improving stability and performance.
