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.
