Abstract: The disclosure provides for a system for correlating user behaviors with wellness outcomes. The system includes a wearable electronic device including a sensor subsystem. The sensor subsystem yields sensor output data spanning multiple days during which the wearable computing device is continuously worn by the user. From the sensor output, behavior(s) and wellness outcome(s) of the user are determined, and a correlation is identified between one or more user behaviors and a wellness outcome. A message based on that correlation is presented on a display associated with the wearable electronic device.
