Weixin, launched by Tencent on January 21 2011 as a iPhone App, is a free mobile communication tool. You can send voice, video, photo and text messages on Weixin, do group chatting, and find people nearby according to location data.
If you are familiar with Talkbox or Whatsapp, you roughly know how Weixin works; it now works on iOS, Android? Windows Mobile and Symbian devices.
Users can login to Weixin with their QQ ID or sign up with phone number or email address.
Tencent CEO Pony Ma announced on Tencent Weibo that total number of Weixin users has reached 100 million milestone. Tencent is also internally testing a related product called Weiyun, which works in a similar way as iCloud.
Weixin had about 50 million users in 2011 which doubled in less than three months’ time. If this trend continues, it might reach 200 million users by the end of this year. And, the growth of Weixin is very important for Tencent as many of its products find it hard to reach high end users.
