Soul, exploration, stranger. Nico is a social entertainment software. In nico, friends can interact through interests, topics, nearby dynamics, life circles and so on. The system will also recommend like-minded friends for users. Everyone on nico runs Soul, Explore, Momo and other apps, all of which are software and social entertainment apps. Because Soul, detective, momo and other apps can completely replace nico in function, the functions should be more perfect and diverse.
