LumiSync: Jet Lag Planner

✈️ 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 all features. For later trips, unlock the day's plan with Premium (annual subscription, lifetime, or a single-trip pass) or by watching an ad.
