YouCanTutor! is a mobile app focusing on improving the academic performances of college-level students in the United States. We build a social network system which allows students to register and provide or receive tutoring and other academic services. Within the app, you can search for available peer tutors and perform interaction including befriending, chatting, and rating,. Our principle is to provide a students to students experience instead of a professor to students experience, which allows more freedom and effectiveness, as well as concentration on individuals. (The current version is only suitable for University of Southern California)
