If your Smart TV has a Google OS, you can directly download the app and use it.
If your TV does not have a Google OS you can use Chromecast OR Onn with Google TV to use the AruvoTV app. You can purchase the Onn device from Aruvo. It comes preprogrammed with the AruvoTV app installed and connected to AruvoTV.
Given that the AruvoTV app is compatible with all TV with HDMI ports, AruvoTV does not suggest any particular TV.
