This application tracks anonymous groups of anonymous people.
To track your anonymous group, name it and share it with your friends (i.e. the "We" entry).
As they name themselves as members of this group, you (i.e. the "Me" entry) and all your group members (each having their different "Me" value) will have access to their latest location report.
A location report is made upon accessing the application, and linked to your group and individual names.
