## Description

Jet lag isn't beaten with willpower — it's beaten with correctly timed light. Lumezone tells you when to seek light and when to avoid it, day by day.

Jet lag isn't beaten with willpower — it's beaten with correctly timed light. Lumezone builds a day-by-day shift plan from published circadian light-timing principles (advance ~1 h/day eastward, delay ~1.5 h/day westward, the "go the other way" rule past 9 hours) and lives on your wrist where the reminders actually reach you.

FREE, WITH NO TIME LIMIT
• 60-second setup: destination, arrival day, your usual wake time.
• Today's instruction: when to seek light, when to avoid it, and today's wake and bedtime targets.
• Optional pre-flight shifting.
• Works completely offline; asks for NO permissions except notifications.

LUMEZONE PRO
• The whole plan, not just today — every day of the shift, before and after the flight.
• Save and switch between trips.
• A tap on your wrist the moment a light window opens.
• Last-caffeine time, every day.
• Complications on your watch face.

Pro is a monthly or yearly subscription. The price in your own currency is shown in the app before you buy.

No account. No servers. No data collection — the trip you type in never leaves the watch.

If you bought Lumezone while it was a paid app, Pro is already yours, permanently and at no extra cost.

Lumezone is a general travel wellness planner. It does not diagnose, treat or monitor any condition and is not medical advice. If you have a sleep or health condition, talk to a qualified professional.

Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically unless auto-renew is turned off at least 24 hours before the end of the current period. You can manage or cancel it in your Apple Account settings.
