Yes, Youtube is the best app in the google play store indeed. You can see all the things you want to know in Youtube. For me, I've been using youtube since 2010 as a platform and as a source of income. I made a channel before for just fun and lately I discover that I can actually earn by that. Youtube helps me a lot especially in making myself more creative. Youtube keeps on improving and upgrading. Making it as one of the most popular website and app in the market.
