There is no doubt that people all around the world use social media apps almost every day. People in different countries have their own favorite apps for communicating. When we open these kinds of apps, we have a lot of online friends, and we have joined a variety of groups to talk about different topics that usually refer to work, life, education, food, etc. In China, the social media app we use the most is called WeChat. It is a tool that is not only for chatting but also for payments, watching videos, or doing business. We can do everything via it. Our lives have changed a lot since it was created 12 years ago. It was developed to make everyone's life more convenient. In fact, we are not happy spending our lives only with a phone. Our lives should be full of plenty of interesting things. Cooking food is more exciting than ordering takeout. Taking a walk in a park is healthier than watching videos all day long. So, just because something is popular doesn't mean it's right!
Some of key corrections I made:
"most every day" → "almost every day" (more common phrase).
"favourite" → "favorite" (American English spelling; use "favourite" if British English is preferred).
"joined into a variety of groups for talking about" → "joined a variety of groups to talk about" (corrected phrasing).
"usally" → "usually" (spelling correction).
"etc......" → "etc." (correct punctuation).
"the social media app we use most called Wechat." → "the social media app we use the most is called WeChat." (added "is" for clarity and corrected capitalization).
"not only for chatting,but also for payment, watching video or doing business." → "not only for chatting but also for payments, watching videos, or doing business." (corrected punctuation and pluralized terms).
"Our lives have been changed a lot since it was created" → "Our lives have changed a lot since it was created." (simplified tense).
"to be convenient." → "more convenient." (corrected phrasing).
