Use Whatsapp via Web!

>> This service can be used via chrome browser on desktops and ‘some’ Android devices. To try it navigate to web.whatsapp.com

>> When you head over to the website you’re greeted with a page with a QR code like the one in the image above.  The page shows us the supported devices which has been increased since yesterday. iOS support should be there soon.  Follow the instructions for each device type and scan the QR code.

>> At the moment, the web application works on Windows PCs and Android devices, but not in mobile or desktop Safari. However, it can be accessed on desktop Macs using Google’s Chrome browser, but not on iPhones and iPads running Chrome.

Seems support for more browsers is “coming soon,”
