As a wechat user(I made my account during a study abroad in China) I think one of the most interesting feature is the mini programs. They're basically javascript applets within wechat with their own API that do whatever an html5 website can do, but specifically integrated with the platform making account registration and payments more frictionless than even "login with facebook"/Apple Pay. For example you may have heard of their bike share(Mobike), uber equivalent(Didi), and grubhub equivalent(ele.me). For Chinese users, these are not simply separate phone apps, but actually accessible within WeChat so they never even have to tab out.
