WhatsApp is a social messaging app to chat online free of cost.I am using WhatsApp from many years.After the WhatsApp Web update, I tried to use it.It’s main use is to use the WhatsApp on PC or Laptop.It sync all the Data and Messages in your Browser on PC like Mozilla, chrome or Internet Explorer.It works on the QR Code scanning.It scans the QR code on web.whatsApp.com and starting syncing.The main disadvantage of it is that for using on PC, it requires the Internet Connection on both mobile and Laptop or PC.So we need extra bandwidth cost.In fact still It’s a very convenient and easy way to use WhatsApp on PC or Laptop through syncing through Mobile.
