Event Calendar started as a replacement for an antiquated script to generate meeting invites with attached ical. It has since grown to be a full fledged event calendar system for public events. Important to Event Calendar is the theory of multiple interfaces, where any data in the system should be accessible in a multitude of ways. For events, this means via nice HTML, iCal, XML, and JSON. Event Calendar also includes integration with Google Maps for directions to event locations.
MoodTrack is a record of observations, events, notes, medications, and doctors that describe a patient. Metrics can be defined to measure the patient's mood, behavior, or other aspects of interest. Caregivers may export the data and send it to medical professionals who have a copy of MoodTrack, and they can import it and then review it to decide if a change in medication or treatment is required. It is not meant to take the place of visits to the doctor, but rather to increase the amount of information available to the doctor.
