Land ready, not wrecked. Jet Lag Time Zone Shifter builds you a personalized plan to beat jet lag before it starts, so you arrive sharp and sleep on local time faster.
Crossing time zones throws your body clock out of sync. This app uses your trip details and your personal chronotype to map out exactly when to seek light, when to avoid it, and when to wind down, helping your circadian rhythm shift toward your destination.
WHY TRAVELERS CHOOSE US

4. Follow simple daily nudges for light, sleep, caffeine, and melatonin timing
GROUNDED IN CIRCADIAN SCIENCE
Your plan is built on well-established circadian principles that researchers use to study how light, timing, and routine influence the body clock. We turn that thinking into clear, practical steps you can actually follow on the road.

- Vacationers who do not want to lose the first days of a trip
- Long-haul and red-eye passengers
- Crew, athletes, and anyone managing shift work or irregular hours

Start a plan a few days before you fly and let the app guide your light, sleep, and timing choices all the way to your destination and back home.

Illogical recommendations
D@isy271
This app’s recommendations are ridiculous. The best example of this is that it told me to get on my flight in the middle of a chunk of sleep. A good time shifting app should recognize that one has to do things… like go to the airport and get on a flight. Seems obvious. So yeah, this is an illogical app.
Developer Response
Hi, thank you so much for your feedback. You’ve raised a very valid point, and we truly appreciate you taking the time to share it. It’s important that the app better aligns with real-world schedules like fixed flight times, and we’re actively working on improvements to handle such cases more intelligently. Feedback like yours helps us prioritize the right updates—thanks again!
Not worth it
nwinlax
My biggest complaint is no way to edit or delete any trip that was created. Time for caffeine is not relevant. The usage of caffeine should be bases on person not by schedule. Presetting coffee schedule has no helps to adjusting jet lag.
Developer Response
Thanks a lot for your feedback! 🙏The caffeine schedule is actually optional — the app asks about your caffeine tolerance at the start, so that part only activates if you choose to include it.I totally agree though, being able to edit or delete trips is super important. It’s already planned for the next update.I really appreciate you taking the time to share your thoughts — feedback like this helps me make the app better for everyone. ☕✈️
