Viber, one of the most popular internal calling services, has expanded its service area. Windows 8 users can now download the app from Microsoft Store for free. The app has already been out on Windows and MAC since the first half of this year. Only now, a fully touch-optimized version for Windows 8 has been released. Conversations can be pinned to your start screen, and contacts can be searched for using the universal search bar on Windows 8. Also, the ability to dock a video call at one corner of the screen while carrying on with your other tasks lets you put your multitasking skills to use.
Viber is turning up the heat on rivals Skype with its new Viber Out service that offers much cheaper rates than the competition.
