Viber is an all-in-one communication application for Windows PCs. You can share instant messages, make live audio or video calls, and express yourself through expressive stickers. It also facilitates you to communicate with your friends via group chats. Since the software runs in the background, it doesn’t waste system resources. The notifications appear in the system tray to keep you updated. All you need to do is to create your account with your mobile phone number and you can use this tool for free. Rakuten Viber launched this software in 2010 for smartphones and later released its desktop version to facilitate users.
Skype is a free communication application that works with desktop systems as well as mobile operating systems.

It’s a resource-efficient tool that doesn’t negatively affect your system’s performance. It helps you keep your contacts in one place and stay in touch with your social circle.
