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).
