About Entrain

Jetlag is the result of a disrupted circadian clock. Entrain simulates your circadian clock on the phone and makes mathematically optimal lighting recommendations to help you adjust as fast as possible to new timezones and schedules. The recommendations, which tell you when to seek light and/or dark, are based on new research in the journal PLoS Computational Biology. Learn more at entrain.org.
