Yuefan is an iOS app that helps busy Chinese college students conveniently find time slots for group meals that work for most people's schedules. The app allows users to set up meals, record other users' availability, and find a time that works for the majority, minimizing the effort to coordinate schedules and invite people compared to other social media options. It aims to help students like Xiaoming, who wants to have a big Chinese meal with friends but finds it difficult to coordinate due to differing schedules without bothering everyone for their availability.
