As we all know, WhatsApp is one of the most known applications, available for any kind of mobile platform. There are many other applications and tools that tried to be like it, like KIK or Group Me tried, but in the end the result was truly bad, so they failed, although there is one exception and it is called the Viber applicaton. This tool doesn’t benefit of too many users as the WhatsApp does, but if you are going to make a comparison between this one and other tools, you will see that this is the most popular and much easier to use when needed.
The Viber application is completely free and can be downloaded right away from the Marketplace.
App price: Free
