Enter your flight times and get a science-backed light and sleep schedule that resets your body clock — arrive rested, not wrecked.
Beat jet lag before it hits. JetLagPlan builds a personalised, day-by-day light and sleep schedule that shifts your body clock towards your destination — so you land sharp instead of wrecked.
Most jet lag apps just tell you the time difference. JetLagPlan does the circadian maths for you: enter your route and flight times, and it works out which direction to shift, how many days it takes, and the exact hours to seek light, avoid light, take melatonin, and sleep. Every recommendation is timed to your departure and arrival time zones — not generic advice.
WHAT YOU GET
- A full day-by-day plan that resets your body clock before you arrive
- Advance or delay shift direction, worked out from your route
- Exact seek-light and avoid-light windows — the fastest lever for shifting your rhythm
- Personalised sleep, wake, and melatonin timing for your route
- Caffeine start and stop times, plus anchor-meal timing to lock in the new schedule
- Reminders for every action so you never miss a light or melatonin window
- Unlimited trips and custom time zones, tracked in one place
PERFECT FOR
- Long-haul and overnight flyers who arrive exhausted
- Frequent business travellers crossing many time zones
- Anyone with one big trip they can't afford to feel wrecked for
- Travellers who want a plan grounded in circadian science, not guesswork
WHY NOT JUST GOOGLE THE TIME DIFFERENCE
Knowing it's 9 hours later doesn't tell you what to do about it. Light at the wrong hour pushes your clock the wrong way and makes jet lag worse. JetLagPlan turns your route into a concrete schedule of when to get light, when to hide from it, and when to sleep — so your body is already adjusted when you land.
LEARN AS YOU GO
The Learn tab has plain-English articles on the science behind circadian rhythms and light exposure, with cited sources — so you understand why each window matters. Melatonin timing is wellness guidance to help you adapt, not medical advice or a prescription.
