It’s a great concept but I think it’s primarily strength is access to broadcast radio stations.
Has a large catalog of radio stations from most countries. However, I noticed USA and Cuba are missing. The TV stations available are very limited and mostly news stations. Also, you can get most of these by going directly to the station’s website and stream in high quality with native support for casting.
It doesn’t seem to support casting but you can open google chrome and cast your whole desktop. I think the media library would be more useful if it organized your personal collection. Better yet, if this had a plugin/addon for Kodi, Plex, Emby, or Roku, it would make this app a must-have for your home theater.
