Its probably the most downloaded app from playstore and appstore. The interface is very simple and Its so easy to use. What I like the most about this app is that almost everyone who has a smartphone , has this app. So you will find all your friends and relatives on wa. It comsumes very less data, so you will msg them, call/video call them at almost zero cost. It consumes surprisingly very less data which is awesome. Be it 2g/3g/4g whatsapp always works on even the slowest net connection.
Hit like if you liked my review.
