A:Answer This TV uses our SmartCast Platform which offers a host of built in apps, as well as support for Google Chromecast, Apple AirPlay 2, and voice support for SIRI, Google Home, and Alexa. If you find there is an app you want to watch that is not on SmartCast you may be able to cast it using Chromecast or Apple AirPlay from your phone or mobile device. However, if you would prefer to use a Fire Stick or Roku device, this TV is compatible with both devices.
