Wechat is another messenger service much like BBM, WhatsApp, Viber and etc. WeChat supports Video Call function over WiFi or 3G networks. This app supports social network integration and you can link WeChat to your Facebook profiles too.
Using WeChat, you can just press the “Hold to Talk” button, record your message and it is sent. Don’t confuse it with Voice Search. Your message actually goes as a voice recording and not as text after voice search. Using the Look Around feature, you can look at the active WeChat users in a particular area and connect with them.
Wechat is cross platform and is currently available for iPhone, Android, Windows Phone, Symbian and BlackBerry.
