Most secure and most personal social networking app in the world! There is Snapchat, hike but that cannot take on whatsapp becuase it’s not exaggerted in features every thing is really functional and logical. But recent update of live status was a bit bummer but I’m glad they bring back old style of status which was signature WhatApp feature. WhatsApp now more secure and safe with dual encryption and it has document support gif support and so on. Nobody can disturb you in here. I think it’s the best social network with maximum privacy and control.
