The apps which might make me feel comfortable and relaxed would be my favorite, or let us say I am really into the apps which help me learn something. Some sorts of social apps used to be my favorite, I can get to know some new friends there, or just like Tiktok for example, which gives me more opportunities to rest my mind and fulfill my leisure time. So, the social apps and Tiktok could be my favorite, till now. That is it.
