Viber has been available on mobile devices for a few years now but finally a desktop client has been released for Windows and Mac.

Rock-solid syncing with mobile devices

The desktop version of Viber is an interesting competitor to Skype and Messages for Mac. Millions already use Viber to chat and make video call on mobile but until now it wasn't possible to use Viber from your desktop. Although it doesn't offer all the functionality of the mobile versions, it's still a very worthy alternative.

The developer of Viber for Mac is keen to highlight that it has superior mobile syncing than competitor products. Viber does a good job of making sure that wherever you left off on your mobile device, your chats can be picked up. Contacts are also synced, although some users already report some problems with this. You can make calls and video chats with other Macs but you can't yet make video calls to mobile devices or do video conferencing using Viber for Mac.

Slick, easy to use interface

The interface is very elegant and easy to use. Anyone who has used Skype or Messages will have no problems using Viber. You'll need to sign-up for a Viber account if you don't have one, which you are prompted to do when you setup the app.

Reliable syncing and good quality video

Viber for Mac generally syncs very reliably and efficiently and the quality of video-to-video on Mac is as good as anything Skype can offer. However, some users have already reported problems with syncing and the lack of ability to call mobiles is a bit disappointing.

A solid IM and VoIP client

Viber for Mac is a solid IM and VoIP client that's worth trying for anyone that's had enough of Skype and Messages.
