VRV is a "fan-first" media streaming app that has a little of everything. From your favorite video, anime, gaming videos, cartoons and more. It gives you a huge collection of tons of content that's easy to cast to the big screen.
If you watch Cartoon Hangover, Mondo, CrunchyRoll or Nerdist, you'll love this app. Instead of subscribing to a lot of these services individually, get access to them all with the VRV app. You don't have to use Chromecast with it, but it makes viewing everything a little better.
