WhatsApp Is Now Available Online
WhatsApp, the popular chat app , now has a web version, although you still need a phone to connect to it.
The new web client basically mirrors the app on your phone to the website. To use it, you need to go to the WhatsApp web page , scan the QR code with the WhatsApp mobile app, and then proceed to enter messages from there. Currently, the web app is compatible with Google Chrome only in conjunction with the Android, Windows Phone or Blackberry version of the mobile app. IOS compatibility is not expected yet.
