Just like with the other platforms, Viber for Linux allows you to place free voice and video calls to other Viber users, as well as send free text messages. You can also add stickers and attach photos to the chats. Another useful function is the possibility of creating group conversations among your contacts.
Viber imports all of your phone's contacts, so you don't have to worry about adding them one by one. It also imports all of the conversations that you've already started on other devices, synchronizing each and every one of them.
The interface is relatively easy to use, showing all of the active conversations at one glance, as well as a list of conversations in general. However, if you start a conversation on your computer and you want to continue it on your phone, you can also do so conveniently just by transferring it.
It's always good to hear that a universal communication solution is available for all existing platforms, especially if it includes Linux the way that Viber for Linux does.
