As compared to other social chat apps now available whatsapp is the top most user friendly app. It means whatsapp is easily understandable by any new user, high quality and all types of smiley. The top most feature is the end-to-end encryption, it gives safe and secure chat between persons. I suggest that it is the best and good messenger app available in the playstore. I also used the most of the another messengers available in the net. But now I only use whatsapp, because it is the only app that give a and easily understandable environment.
