## What is Chronicle (Baylor TECH Study)?

Chronicle is a passive sensing application for behavioral research studies. Participants must first be enrolled in an approved research study and be possession of a unique enrollment link provided by the researcher in order to provide data. This application also queries, but does not collect step counts from HealthKit as a workaround to known SensorKit limitations.
