Chrome client instead arrives with Android, BlackBerry and Windows support
MESSAGING APPLICATION WhatsApp is now available via Google's Chrome browser, unless you're an iPhone user.
The web client will allow users to send and receive messages within the desktop Chrome browser.
But Koum is keen to point out that WhatsApp Web is only an extension of the service's mobile apps, so you'll still need your phone nearby to take advantage of it.
"Today, for the first time, millions of you will have the ability to use WhatsApp on your web browser," he said.
"Our web client is simply an extension of your phone: the web browser mirrors conversations and messages from your mobile device. This means all of your messages still live on your phone."
However, while iPhone users are typically the first to get their hands on new apps, WhatsApp announced that - for now at least - WhatsApp Web won't be available on iOS, citing "Apple platform limitations".
Instead, WhatsApp Web currently plays nice with Android, BlackBerry, BlackBerry 10 and Windows Phone.
