I am using whats app about 5 years if you are social-site lovers this app is best for you . you can easily share photos, video, document pic etc by simply using whats app you can make your own group and can send your personal review what you have been done towards your life etc. you can also use its calling feature for calling it is best for calling for any what sapp user if you dont have an account on whats app go makes them now and share your views about the app . I personally loved this app because all my work completed through this app but the minus point of the is there is no option of video calling so I give five out of four star to this app you can also try it please download.
