The popular free calling and chat service Viber has expanded its availability today and has now hit the Windows 8 Store.

The release comes 7 months after the company released Viber for PC and Mac and the new app is fully optimized for the Windows 8 touch interface. You can now pin conversations to the Start screen or dock Viber on the side of the display with the Windows 8 Snap View feature.

Viber has also integrated with the universal search of Windows 8 and you can look up for contacts using the search charm. Switching between desktop and mobile modes is easy too and requires a single button tap.

Talmon Marco, the CEO and founder of Viber commented on the release saying this is a natural next step for the service following the support for Windows Phone 8. Viber recently unveiled it’s Viber Out calling service that gives Skype a run for its money.
