We use so many apps. But the most popular one is Facebook. I suppose for everyone in my country, Facebook is a part of their daily life. For most people, they can't live without using Facebook app even for a day. But that's my opinion based on myself. Most people use this app to share their photo and life experiences to the wider public audience. And they made online business like online shopping. Another thing is we can't go to university and schools because of covid-19 and political issues. So they decided to keep learning something through online class. Some use Instagram too. But it's not convenient like Facebook for most people. But Instagram has its own advantages too.
By using Facebook, we can catch up the latest news by following and subscribing the news media.
