The YouTube Go app has arrived in India. You can get the beta version (no stable release for any market yet) of the app from Google Play in the Asian country. YouTube Go is trying to improve video watching experience in regions with comparatively slow internet. It's similar to the regular YouTube for Android app, except that it gives the option to download a video for offline viewing. The app only offers Basic and Standard viewing quality (144p and 360p) - no HD quality available. Source | Via
