Popular messaging app Viber, which already boasts 200 million users, now has you covered on your PC and Mac desktop computers as well as your smartphones and tablets.

The app, which allows users to send free instant messages and telephone calls, is one of a leading group of services such as Skype, Whats App and Google Voice, which are challenging the business models of mobile carriers and other telecommunications companies with their low-cost and no-cost services.

“People spend a substantial amount of time on their smartphones.

However, a lot of that usage takes place at home or in the office, where they have laptops or desktops close by,” Viber CEO Talmon Marco said in a statement, explaining the need for the desktop extension.

Besides working on desktops Viber 3.0 also includes video messages and the ability to toggle from one device to another with a single click or tap.

Viber is available in 27 languages and 193 countries and claims to be adding 400,000 new customers a day.
