Engadget reports that HBO has released its own streaming video apps for Android and iOS (iPhone/iPad). Both apps are free. However, you need to be an HBO cable service subscriber in order to access the content.
One interesting and important difference between HBO’s video streaming app and Time Warner’s is that HBO subscribers can watch streamingn video outside of the home using 3G or 4G wireless data service. I would be cautious about how much video I watch if my 3G or 4G service had monthly data bandwidth caps.
Note that there are at least two apps from HBO for both Android and iOS. “HBO GO” is the name of the streaming app for both platforms. The other app named simply “HBO” (again for both platforms) provides clips and background information.
