Jetlag Coach: Jet Lag Planner

Jet lag isn't bad sleep. It is your body clock still running on the time zone you left. Jetlag Coach builds a personalized plan to shift that clock faster, timed by science.

You give the app your usual sleep schedule, your chronotype, and your itinerary. It returns a continuous timeline covering the days before you fly, the flight itself, and the days after you arrive. Each block tells you when to sleep, when to seek bright light, when to avoid it, when caffeine helps, and if you opted in, when to take melatonin.

Two flights with a long layover in Doha? A round trip where the return leg arrives before you've finished adjusting? Jetlag Coach handles any combination — one-way, round trip, multi-city, multiple layovers — and merges everything into a single coherent timeline. The engine accounts for the time zone of every stop, not just your final destination.

What you get:
- A personalized plan based on your sleep pattern, chronotype, and trip
- One continuous timeline across pre-trip, in-flight, and post-arrival days
- Multi-leg trip support
- Sleep, light, caffeine, and optional melatonin timing
- Notifications at the moments that matter

The body clock responds to environmental signals, and the strongest of these is light. Light delivered at the right time relative to your current phase pulls your clock toward the destination. Light at the wrong time pushes it the wrong way and slows adjustment. Sleep timing and caffeine reinforce the shift. Melatonin, taken carefully and only if you choose, can support it. Jetlag Coach applies decades of circadian science, the same principles used in aviation, military operations, and elite sport, to your specific trip. The plan adapts as your clock shifts. Each day is timed to where you actually are, not just where the destination clock says you should be.
