Wechat is a downmarket chatting app for smartphone. Although it has many good features like funny stickers, voice calling, video calling, cool emos(:xoxo is my favorite) etc., it cant stand before whatsapp and hike messenger. It is too much slower than whatsapp and hike.
It takes extra data while chatting or sending files. Hike messenger has cool background changing option at chatting page but Wechat has nothing like that. The layout and design is simple and boring.
Now a days Wechat is offering talk-time and other prizes to attract people. All you need just have to send a sticker in a group chat. I use wechat only for this kind of offers, not for chatting. None of my friends use wechat.
