Now a days very social apps are developed but the whats app is the best app that I have ever seen it becomes so easy to text, voice chat and video chat on it compare to other app and many people dont like any other except whats app if you are new user on it you can easily register by simple steps and have fun.
I dont use and like any other app I use only whats app it has fast service but the quality of video chat is little bit not good. In the world almost people utilise it and it became utility of everyone the new version of whats app is full of new features like sharing location etc. I recommend to everyone who have not used it yet just try it for once.
Thanks to see my review
