This article explains how to add apps to your Vizio Smart TV with SmartCast. Additional information is provided for older Vizio TVs with Vizio Internet Apps (VIA) and Vizio Internet Apps+ (VIA+).
How do I install apps on a Vizio Smart TV?
SmartCast TVs come with a wide selection of over 100 pre-installed core apps that are available on your SmartCast home screen. There is no functionality to download additional apps; however, new apps are released periodically and are available immediately following an update.
If you want to use an app that isn't available on your screen, you may still be able to access its content by downloading the app to your mobile device and using the TV's built-in Chromecast or AirPlay technology.
Casting to your Vizio TV works the same as casting through a Chromecast device.
