Yo! Wutup is a social event management service that allows users to create and promote events, invite friends to events, and register for events. Events can be searched by category, geography, sponsor, or date range. The service connects to social networking sites like facebook and twitter for promotion and registration, and exposes a RESTful API so developers can generate any number of clients (web, mobile web, iOS, Android, an so on).

The project was developed by the LMU CMSI 401 Software Engineering Laboratory class during the 2012 fall semester.
