Monitor your body's circadian clock using your smartphone. Adjust faster to new time zones and schedules.
Entrain is a free app that connects users to lighting schedules developed by researchers at the University of Michigan. These schedules are mathematically proven to adjust you to new time zones as quickly as possible. Light is the primary driving input to the circadian clock, and by recording your lighting history, we can simulate your body's clock and make recommendations for behavior.
