As you all know youtube is an video Sharing website though it is the worlds second largest search engine the content available cannot be expected to be of quality and even cinsiderable because anyone can post a video that means anyone, The app seems to do well not as well as the youtube site, as the site offers many options rather than on the app. The youtube app supports offline mode but again it only works in the app itself, and also your cell has to have internet cinnection every 29 days or your offline videos are no more, overall it needs improvement in UI and ih god they really have to lwork on their video recommendation’s on home page.
