YouTube 13.19.7 for iPhone - Download
The official YouTube application is here
Enjoy the site's extensive video catalog from the palm of your hand, playing everything from home videos to official music videos from some of the world's hottest bands.
You have two options to search for videos; you can type in your query or speak it into the iPhone's microphone.
You can also vote on videos, read and leave comments, and enable subtitles from the application - in other words, practically any activity you would normally do on the web browser version of YouTube, including sharing any video through Google , Facebook, or Twitter.
YouTube is a priceless app for registered YouTube users who are actively uploading videos, leaving comments and votes and otherwise taking part in the video portal's active community.
