No idea

Does anyone know if there's a youtube downloader app available on an android phone? I've been having trouble accessing youtube on my phone due to some technical difficulties (read: stupid phone). Some stuff I want to watch on youtube are not available to watch on a mobile device. Why is that I wonder? If it's connected to the internet, I don't see why it matters what device I use or not.

Oh well, I guess I'll never understand technology. Though I'm proud to say I've come a long way in comparison to where I was years ago in terms of computer technology.
