WeChat is a complete mobile communication tool made in China, but with world standards.
The app started in China in 2011 and took some time to expand to the world. Now it has gone viral and has hundreds of millions of users around the world, and stands as serious competition to WhatsApp , Viber , and ChatON .
It has more features than those and is free for good. It comes with instant messaging, voice calling, high-quality video calling and a lot of other features. The interface, however, is not that easy to grasp, but for any tech-savvy mobile user, getting acquainted is not a problem.
