The document discusses an app that allows users to quickly send a message to their friends asking if they want to hang out. It would simplify the process of finding friends who are free by letting recipients respond with just a yes or no, and the sender could then initiate a message conversation with those who said yes. Currently, messaging each friend individually takes time and is repetitive. The document also briefly mentions the app has a major competitor called "Free" as well as other competitors like Facebook Events and SMS. It provides the problem of time-consuming individual messaging that the proposed app solves through a streamlined notification and response process.
