Build your first complete plan free. See sleep, light, and caffeine steps in each city's local time, then save the full itinerary as an image.
Jet lag is not just about bedtime. Your body clock responds to the timing of sleep, bright light, caffeine, and travel across time zones.
Jet Lag Bye turns your itinerary and usual sleep schedule into a personalized, day-by-day adjustment plan. See what to do before departure, during your flight, and after arrival—so every recommendation is clear and practical.
YOUR FIRST COMPLETE PLAN IS FREE
Create your first full travel plan free as a one-time local offer, with no card required. Choose a one-way or round-trip itinerary, follow the complete recommendations, and keep the plan saved on your device. Reinstalling does not reset the offer; restored app data may preserve prior eligibility.
PERSONALIZED FOR YOUR TRIP
• Search by airport code, city, or address
• Plan one-way and round-trip travel
• Get guidance tailored to your route, flight times, and normal sleep schedule
• Prepare before departure, manage flight day, and adapt after arrival
CLEAR TIMING, NOT VAGUE ADVICE
• Target sleep and wake times
• When to seek or avoid bright light
• Caffeine timing and cutoff guidance
• Optional melatonin timing
• A step-by-step travel-day timeline
• Each action labeled with the correct departure or destination clock
BUILT TO FOLLOW
• Check off recommendations as you complete them
• Revisit your saved plan and trip history
• Save the full itinerary as an image in Photos
• Use optional reminders to stay on schedule
• Read comfortably in light or dark mode
MORE PLANS WHEN YOU NEED THEM
After your free itinerary, choose the access that fits your travel:
• Single Trip Plan: create one additional complete travel plan with a one-time consumable purchase
• Annual Unlimited: create unlimited one-way and round-trip plans while your subscription is active, plus access Reset Sleep for everyday schedule changes
Payment is charged to your Apple Account at confirmation. Annual Unlimited renews automatically unless canceled at least 24 hours before the end of the current subscription period. You can manage or cancel it in your App Store account settings. Availability may vary by region.
PRIVATE BY DESIGN
No Jet Lag Bye account is required. Your plans and sleep preferences are stored locally on your device. A non-identifying local marker remembers whether the free itinerary was used and may remain after reinstalling; device backups may preserve other local access state. Location search is used to identify places and their time zones.
IMPORTANT HEALTH NOTE
Jet Lag Bye provides general educational guidance, not medical advice. Recommendations may not suit everyone. Consult a qualified healthcare professional before changing your sleep routine or using melatonin, and whenever you have a medical condition or concern.
