As being a WhatsApp user I can say that the whatsapp is one of the best app.
the app was launched to chat with your friends freely through internet.
the layout and the design of the app is created by the experts which looks too good and works faster.
their are so many features which can be used in the app such as messiging and calls and you can also apply a
profile picture which could be showed to your friends on their whatsapp .
the features are also same as other messingers but through this you can also make calls so this thing makes this app more good than other apps.
it is used to chat or send some photos, videos, audios etc.
