Beat jet lag with a personalized plan. Science-backed sleep, light & caffeine timing for your exact flight. Arrive refreshed, not exhausted.
Jetly helps you beat jet lag before it starts. Enter your flight details and get a personalized, multi-day adjustment plan based on circadian science
— so you arrive feeling sharp, not shattered.
HOW IT WORKS
1. Add your flight — Enter your route, departure time, and travel date
2. Get your plan — Jetly calculates a day-by-day schedule starting before your flight
3. Follow the timeline — Clear visual guidance for sleep, light exposure, and caffeine timing
YOUR PERSONALIZED JET LAG PLAN INCLUDES
• Sleep Schedule — Know exactly when to go to bed and wake up, with gradual shifts starting days before departure
• Light Exposure — Timed recommendations for seeking bright light, some light, or avoiding light entirely to reset your internal clock
• Caffeine Windows — Precise times when coffee helps your adjustment and when to cut it off
• Flight Day Strategy — Optimized schedule for sleeping on the plane and transitioning to your destination timezone
• Post-Arrival Routine — Continue your adjustment after landing with daily guidance until you're fully synced
BUILT ON SCIENCE
Your circadian rhythm shifts at roughly 1 hour per day. Jetly uses this principle to calculate optimal timing for light exposure, sleep, and caffeine
— the three most powerful tools for resetting your body clock. Plans account for flight direction (eastward vs westward), timezone difference, and
your personal sleep pattern.
DESIGNED FOR TRAVELERS
• Works for any flight crossing 3 or more time zones
• Supports over 114,000 flight routes worldwide
• Pre-flight preparation starts 2 days before departure

PERSONALIZED TO YOU
Set your usual bedtime, wake-up time, chronotype (early bird, night owl, or neither), and caffeine preference. Jetly builds every plan around your
actual sleep habits — not generic advice.
