Circadian rhythms drive much of our health, but are not well understood. Our App, Metabolic Compass, is designed to collect information on when we eat, when we sleep, and when we exercise. These events are displayed for users to quickly see their daily behavior within a weekly context. Our long-term goal is an understanding of how daily timing decisions impact our health.
