Jetlag App

A web app that builds a personal, day-by-day jet lag plan from your flight details.

Jetlag App builds a personal jet lag plan from your flight details. Instead of one-size-fits-all advice, it calculates how many time zones you cross, in which direction, and how hard your body will resist.

The result is a clear plan from three days before the flight to the days after arrival: when to sleep, when to get sunlight, when to stop the coffee. No signup is needed, and your data stays in the URL rather than on a server.

Key features

  • Just enter departure, arrival and date; no signup
  • A day-by-day plan from three days before the flight to after arrival
  • Timing for sleep, light, caffeine and melatonin
  • Grounded in circadian-rhythm research, accounting for flying east versus west
  • Add plan milestones to your calendar
  • Ready-made guides for popular routes

Who it is for

Business and holiday travellers crossing time zones, frequent flyers and cabin crew.
