1. Introduction
● Societal Problem
o Organizing events around the schedules of multiple people can be difficult and
often involves back-and-forth communication as overhead. Existing calendar apps
are not well-suited to quickly and easily schedule social events to take place in
leisure time.
● Problem Characteristics
o Time wasted on communication overhead
o Existing apps target business and education
o What about social events in leisure time?
o Examples: friend groups, gamers
● Solution Statement
o We can streamline this process and make scheduling events outside of work and
school more accessible to everyone.
● Solution Characteristics
o Privacy controls at the event level
o Users specify available time blocks and preferred activities
o Users can view the availability of friends
o The system automatically suggests times when all people in a group are free
o Single calendar and friend list for each user
