This pphour is made for people who have the PCH or popcorn hour media streamer and or a Plex Server running. You can control your PCH ( popcorn hour ) via this app. If you have a home Plex Server running you can interact with the server to view media. If you have plex running and a popcorn hour you can fling your content from plex to the popcorn hour. That last step includes you also having installed the free NMT software Plonk or something similar. I have also added some Apple Watch functionality to it as well. You can now view / play media via the watch as well as some basic remote controls for the PCH ( popcorn hour ). You can add 1 or many popcorn hours as well as one or many Plex Servers. I have two popcorn hours an a100 and a c200. It works well with both.
