Plex is a media streaming powerhouse for all of your content needs. Not only does it organize your video, music, and photo collections, giving you instant access on all of your devices, but Plex is also the last app you will ever need for personalized video news. AND, with our premium Plex Pass, you can record over-the-air television and watch anywhere with a supported digital antenna and tuner. Using the free Plex Media Server software on your computer, NAS, or favorite cloud drive (Google Drive, OneDrive, or Dropbox), plus the Plex app, you can enjoy all of your media–even that DVR-ed content!–on all your devices.
Note: If you’ve already purchased the app through the Google Play store or you have a Plex Pass, you do NOT need to purchase again! Your previous purchase will be automatically detected.
BONUS FUNCTIONALITY: Fling photos and videos from the Camera Roll on your phone or tablet to Plex apps on virtually any platform; unlimited streaming of any media on your Plex Media Server to other Plex apps; remote control Plex on your big screen using your mobile device. LIMITATION: Playing media from your Plex library on the device running this app is limited (one minute for music and video, watermark on photos) until the app is unlocked. FOR FULL FUNCTIONALITY: Remove the playback limitations on the app with a Plex Pass enabled account -OR- make a small, one-time, in-app purchase for only app access.
