JetLagPlan: Beat Jet Lag

Turn your flight into a clear day by day plan. See when to seek light, when to keep it dim, and when to time caffeine and melatonin to help your body clock catch up.

Long flights leave your body clock in the wrong time zone. JetLagPlan turns your trip into a clear, day by day plan so you know exactly what to do with light, sleep, caffeine, and melatonin to help your body clock catch up.

Tell it where you are flying and when. JetLagPlan reads the time change, works out which way your clock needs to move, and builds a personal schedule for the days before you leave and the days after you land.

WHAT YOU GET • A plan built from your own flight: cities and times • The direction of the shift, the size of the time change, and how many days to adjust • When to seek bright light and when to keep it low, for every day • A day by day sleep schedule that eases toward the new time zone • A caffeine cutoff and an optional evening melatonin time • A body clock chart that shows your progress, about an hour a day • Plans for both eastward and westward trips • A plain language explainer of the science behind every step • Daily reminders that follow your plan, so each step happens on time • A pace control: shift gently, at a standard hour a day, or faster • One tap to build the return trip • Arrival readiness that shows how adjusted you will land • Backup and restore your trips to a file, all on your device • Cited sources on every guidance screen, from the NHS, the AASM, MedlinePlus, and the CDC
