Sangha is a new (free) iOS app communications/calendar app for schools. This is a great app that gives teachers/parents the same calendar across any platform. This way educators can schedule anything they want (i.e. parent conferences), classroom reminders, etc. and then parents can sign up via a e-signature form. Also, teachers can send messages w/ attachments as well as private message others and organizations.
