The guy who made the Alien Blue Reddit client for iPhone and iPad has come out with Jasmine, a Youtube client. It's a great minimalistic approach, and IMO has way better control over stream quality and subscriptions. Plus it's free, so just try it for yourself. I'm in no way affiliated with the dev, I just am a fan of this app (and Alien Blue). Here's a link: http://itunes.apple.com/app/jasmine-youtube-client/id554937050
Edit: Oh yeah, unlike Google's app, it also works on iPad!
