LumiSync - Jet Lag Planner

Adapt faster with light timing

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Losing the first days of every trip to jet lag? Get a personalized, day-by-day plan for when to seek light, sleep and eat — tuned to your own flights. Losing the first days of every trip to jet lag? LumiSync is a jet lag planner grounded in sleep research. It tells you when to seek light, when to avoid it, and when to sleep — all tailored to your trip. No pills: just light and your daily routine, timed to shift your body clock to the destination faster. WHY LIGHT? Jet lag happens when your internal body clock is out of sync with local time. The most powerful signal for resetting that clock is light. LumiSync estimates your core-body-temperature minimum (CBTmin) and uses it to work out, day by day, when to get light and when to stay out of it. KEY FEATURES • Personalized plan — built from your usual sleep pattern, chronotype (morning/evening person), age group and flight times • What to do now — the home screen shows "get light / avoid light / time to sleep" at a glance • Adaptation timeline — a graph of how your schedule shifts over the days after arrival • Destination clock — local time and home time, live, side by side • In-flight plan — when to sleep or stay awake during the flight, layovers included • Meal & caffeine timing — eat on destination time to help the shift along • Melatonin (optional) — if you take it, guidance on the right timing • Reminders — so you don't miss light, sleep and meal windows • Short-trip mode — for 2–3 day trips it suggests staying on home time instead of forcing a full shift GREAT FOR • Frequent long-haul travelers and business trips • Anyone who wants to feel good from day one at the destination • People who prefer to reduce jet lag without sleeping pills • Athletes, crew and others for whom jet lag management matters THE SCIENCE Designed from research in sleep and chronobiology: the light phase-response curve (Khalsa 2003), clinical jet-lag guidance (Eastman & Burgess 2009), and meal timing and peripheral clocks (Fuller 2008). PRICING Your first trip is free with every feature. For later trips, unlock the day's plan with Premium (an annual subscription, a lifetime purchase, or a single-trip pass) or by watching an ad. Core features like the destination and home clocks stay free. NOTE LumiSync is an informational tool, not a medical device. It does not replace medical advice. If you have a sleep disorder or are considering medication (including melatonin), consult a professional. Beat jet lag with light. Arrive ready with LumiSync.
