Whatsapp announced that it user will now be able to use
whatsapp features in a native desktop app. This native app will be available
for modern version of OS of Window 8 and above and mac running OSX 10.9 and
above.
Although Whatsapp Web is still available to both OS
regardless of Version.
To start using this Application is very simple. First, Visit
whatsapp.com/download with your browser, download and open the pertinent app,
scan the QR code with the whatsapp Application of Your Mobile Phone.
If you are stuck on how to scan the QR code, go to setting
> Whatsapp Web. This deskop
application is the same with the mobile what but the little different I see is
that it has a customized notification, better keyboard shortcut etc.
