Fully supported platforms
Android TV and Google TV cover Sony Bravia, Nvidia Shield, TCL, Hisense, Chromecast with Google TV, Xiaomi Mi Box, and ONN Walmart boxes. Fire TV Stick Lite, 4K, 4K Max, and Fire TV Cube support SmartTube through Downloader sideloading.
Samsung and LG smart TVs
Samsung Tizen and LG webOS do not run SmartTube APKs natively. Plug a Fire TV Stick or Chromecast with Google TV into HDMI, install SmartTube on that device, and use it as your YouTube front end.
Searches like smart tube samsung tv or smarttube tizen describe this workaround rather than a native Tizen app.
Chromecast models
Chromecast with Google TV (the remote model) installs SmartTube like any Android TV device. Older cast-only Chromecast dongles cannot sideload APK files.
Android phones and desktop
Android phones and tablets are the easiest way to download the latest SmartTube APK and send it to your TV. The app UI is built for television screens, so daily viewing works best on Android TV or Firestick. iPhone, iPad, Windows, and macOS users should use the official YouTube app or add an Android TV stick.
