Well, I think all possible kinds of apps. Many people use news apps because it's important for everyone, especially nowadays, to keep up with current events and know what is happening in the world. Also, a number of people play mobile games just to relax or pass the time while waiting for somebody or queuing. Apps for business are popular too, for example, email apps, apps for editing documents, reminders, notepad apps, a currency converter and a calculator. People want to be able to do their work wherever they are, even on the go. Finally, many people in my country use productivity apps such as a photo editor, an alarm clock, some trip planners, to name but a few.
