Whatsapp is very useful and best messaging app.I am using this app from more than 3 years now.
nowadays everyone is using WhatsApp Messenger because it is very useful and easy to use app.
we can share photos videos songs and even PDF files.
the user interface of WhatsApp is very easy to use.we just need our mobile number to create an account on WhatsApp.
it is way better than many social apps because you add only those people who are on your contact list.
easy to use interface and it's useful features makes it the best messaging app.
