Jetlag Coach

Jetlag Coach creates a personalized circadian schedule to help you adjust faster across time zones. Enter your itinerary and preferences to get timed guidance for sleep, light exposure, caffeine, and optional melatonin.

It uses research in circadian biology to start adaptation before you fly and realigns each day's plan as your body clock shifts. Following the schedule helps reduce fatigue, recover alertness sooner, and make the most of your trip.
