There are two aspects or roles to Plex Companion:
- Controller: This is the Plex app you use for control. Think of it roughly as the “remote control device”.
- Receiver: This is the Plex app that’s used to actually display and play back the content.
Many Plex apps are able to play either role, but some are more restrictive.
