The best app where we can learn about everything and anything. Iam learning java classes using YouTube. They are really awesome. They explains everything in detail. We find lot of videos regarding every topic. Now a days am learning cooking classes in you tube we can find number of videos for single receipe.I have learnt some receipes and tried them too which was a good experience. We can find every video in any language we want dat is the good thing so that we can understand everything very easily. This is the platform where we can learn everything without any hesitation. There is no cost to pay for this app but the Internet is necessary and if not we can also save the videos to offline so that we can watch them offline also.really superb app for learning.
