It seems the day many people have been waiting for is finally here – WhatsApp is now available on your desktop, but only if you’re an Android, Windows Phone or BlackBerry user.
WhatsApp, the popular chat app, now has a web version, though you'll still need your phone to connect to it.
The new web client basically mirrors the app on your phone onto the web site. To use it, you need to head to the WhatsApp web page, scan a QR code with the WhatsApp mobile app, then get to typing your messages from there. Right now, the web app's only compatible with Google Chrome in combination with the Android, Windows Phone, or Blackberry version of the mobile app. iOS compatibility isn't on the way for now
