Real Madrid have announced that it will be totally free to watch Real Madrid TV on the official Real Madrid App. You can download the App for Android and iOS devices, and it will be available for Microsoft software soon enough as well.
Here's Real Madrid's article about it.
Realmadrid TV is now available to be watched free-to-air, both in Spanish and English, through the club's official application. Real Madrid's millions of fans can stay up-to-date with the latest club news via their mobile devices and anywhere in the world.
Realmadrid APP can be downloaded to smartphones on both the IOS and Android markets. It will also be available from the Microsoft Store shortly.
This is certainly good news for madridistas around the world, although the official TV channel still has room for improvement. In the meantime, you will now be able to catch pretty much every Real Madrid Castilla game live, if you're interested in seeing Zinedine Zidane's coaching skills.
