Nearly three months after the launch of the latest major iteration of Apple’s mobile operating system, WhatsApp Messenger has finally been updated for iOS 7.

This means, of course, that the popular messaging app has been redesigned with a new interface based on the visual style of iOS 7.

Even while on iOS 6, WhatsApp already felt outdated and looked — for lack of a better word — ugly. So, its new iOS 7-optimized look and feel is indeed a sight for sore eyes.

As expected, WhatsApp’s iOS 7 interface is cleaner, simpler, and flatter. It actually arrives as previewed from a beta version of the app’s update a couple of months ago.

The latest update to WhatsApp also adds support for one of the new features in iOS 7, Dynamic Type. As a result, WhatsApp now uses the systemwide text size as configured in the iOS Settings app.

But perhaps the most notable feature introduced alongside WhatsApp’s iOS 7 interface is support for broadcast lists. Similar to BBM‘s Broadcast messaging feature, this enables WhatsApp users to send messages to multiple contacts at a time.

The new WhatsApp update also delivers the following enhancements:

  • improved share location: 3D map view, hide places, search places
  • large thumbs: see more
  • new notification alerts and sounds: WhatsApp Settings > Notifications > New Message.
  • new improved User Interface for managing your blocked contacts: WhatsApp Settings > Chat Settings > Blocked
  • crop image before sending

Also featuring a flatter app icon, the new iOS 7-ready version of WhatsApp Messenger is available now in the App Store for free. The app is optimized for iPhone and iPod touch running iOS 4.3 or later.
