Apple’s own iMessage app, which comes gratis with Mac OS X, is a great app.  However, it does have a drawback: it doesn’t allow cross platform messaging (Which is Really important!). Well, all is not lost! Just download the latest version of Viber: an application for Windows, Mac and Linux, which allows for messaging across platforms.

Viber is freeware, which provides two key functions. There’s text chat, which is much like SMS messaging, but with the ability to send images too. Then, there’s voice calling; Viber boasts high definition audio for superb quality and clarity.

One outstanding feature of Viber is that it allows users to transfer a call from one device to another – a superb feature that its competitors inexplicably lack.
