YIN is a social networking app designed for college and university students to connect with peers on campus and in their city. With YIN, users can stay updated on events, questions, and stories happening in real-time within their campus and surrounding areas. This app allows students to interact with one another, manage their student life, and find like-minded individuals based on shared interests and personalities.

YIN enables users to create polls, use GIFs for posts and comments, and connect anonymously with other students nearby. Developed by students at Cal State Fullerton, YIN aims to provide a platform for students to engage with their campus community and beyond.
