我刚刚在 iphone 上查了一下，iphone 里的应用的确是叫 WeChat～ 然后我在网上搜了一下、
WeChat (Chinese: 微信; pinyin: Wēixìn; literally "tiny message") is a mobile phone text and voice messaging communication service developed by Tencent in China. The application was initially launched as Weixin in China in January 2011, with international language support in October 2011, and re-branded as WeChat in April 2012.
所以如果你想用英语解释这个单词，那么可以翻译成 Tiny Message / Tiny Chat.
不过如果你是想用英文来跟某人介绍的话，可以直接用 WeChat、The WeChat App.
