Wechat is an app with which you can chat with your friends, it is not so well designed but can be easily accessed app, It has got many a features You have got here File Transfer, where you can transfer files with your contacts or with plugins, yes plugins too, you can connect twitter, facebook but they doesnot work properly Concept is very easy it’s a social app to connect with your friends, shaking feature of this app has poor performance, but has drift bottle feature which makes it unique, Being a Chinese social app, whenever you stumble upon on someone or someone stumble upons you he/she happens to be a chinese. Rarely you will meet an english one, fradulent app takes lots of time to load< it’s usefulness are that you can do voice messages, do videocalls, file transfer and etc, but not a reliable app, doesnot protects user data, donot care about your privacy, If I have to suggest something that is not to use the app bad app, fake application, uses RAM a lot, not useable kind of app.
