You Tube's become so big -- full of cat videos, music, let's-plays, vlogs, comedy and much more -- that it's hard to find the specific videos you want.
With a You Tube Red subscription, you can download videos to watch offline with the i OS and Android apps, plus listen to videos in the background while you do something else on your phone or turn off the screen.
Use this app for: Listening to music, watching music videos and discovering new tunes, online and off.
Watching other people play video games is a recent cultural phenomenon, whether it's to share the frustration of a difficult level, learn how to beat part of a game or just be a spectator while someone else plays and entertains you.
The main You Tube app is the most widely available; you can use it on Android, i OS, the Microsoft Xbox One, Xbox 360, Sony Play Station 4, Play Station 3, Nintendo Wii U, Wii and 3DS, plus many smart TVs.
Use this app for: General-purpose You Tube viewing and keeping up with new videos from your subscribed channels.
