There isn’t anything different in the version for Android, it contains OneGuide support, the ability to find and favorite channels, universal remote, and more. However, it’s Beta, and there are known issues listed right on the Play store download page. Potential users should read these and beware of certain bugs that could prove frustrating.
The app is free to download, requiring users to be running Android 4.0 or newer of the operating system. That should encompass most users at this point, as Gingerbread has finally begun to disappear, after once seeming as though it would be the XP of Android.
