Free calls app announces it now has 200 million regular users – although that is fewer than a third of its Microsoft-owned rival.
The free calls app Viber is to challenge Skype's domination of the free internet phone services market by extending its service to desktop computers for the first time.
The move comes as the company announced it now has 200 million regular users, up from 140 million at the end of 2012. The figure is a major milestone for the Cyprus-based firm – but it is still dwarfed by Skype, which has more than 600 million users, and the heft of its owner, Microsoft, behind it.
Like Skype and free texting phone app Whatsapp, the Viber mobile client offers free messaging and calls. The desktop version is the first in its suite to offer video calls.
