The Roku app on mobile devices is primarily an alternate remote control for Roku devices and TVs.
Streaming rights for televisions, desktop computers, streaming devices, and mobile devices are all licensed separately. You can view Roku's own The Roku Channel via their mobile app, but not other channels for which Roku does not have the right to stream to mobile devices.
