VIBER Desktop-PR_MaciPhoneViber yesterday launched desktop applications for both Windows and Mac OS X that feature support for video calls (in beta), making it a head-to-head Skype challenger

Viber has been focused squarely on making its service available on as many mobile platforms as possible, releasing apps for iOS, Android,Windows Phone, BlackBerry, Symbian and even Samsung’s Bada.

But today marks the release of Viber Desktop for PC and Mac, desktop versions of the service that integrate with the existing, aforementioned mobile versions of the app. It also comes with the same dead-simple setup process that employs a user’s phone number as their ID.

Desktop users will be able to transfer calls between Viber Desktop and mobile apps with a single click or tap, sync received and sent messages, and be able to delete conversations on whichever device they choose.

Viber Desktop for the first time allows users to make video calls. This new (beta) feature lets users make desktop-to-desktop video calls to other Viber users for now, but the company will likely bring the functionality to mobile platforms in the future.

The launch of the desktop apps is not the only product-related announcement Viber is making today, however, as it is also rolling out Viber 3.0, a major update to both the Android and iOS versions of the communications service, and a new app for BlackBerry that ensures voice calling as well as compatibility with Viber Desktop.

Viber’s Android application in addition now features a completely redesigned “Holo” interface and a number of other, Android-specific optimizations.

Viber also announced yesterday that it had hit 200 million users from 193 countries across all supported platforms, up from 140 million users at the end of last year and 175 million users at the end of February 2013.

It has added support for eight new languages, bringing the total of languages supported to 27 languages overall.
