v3.5 is here! Polished design with redesigned plan view, clear visual indicators, and circadian science. Plan multiple trips and beat jet lag.
CURE YOUR JET LAG BEFORE IT STARTS
Jet Lag Cure uses proven circadian science to create personalized recovery plans that help you arrive refreshed and ready. Unlike generic advice, our algorithm analyzes YOUR specific travel details to generate a custom body clock adjustment schedule.
WHY JET LAG CURE WORKS
Your body has an internal clock that controls sleep, energy, and alertness. When you cross time zones, this clock gets disrupted causing fatigue, insomnia, and poor performance. Jet Lag Cure helps you strategically shift your circadian rhythm BEFORE and DURING your trip.

- Flight crews managing irregular schedules
THE SCIENCE BEHIND IT
Our algorithm is based on peer-reviewed circadian rhythm research. We calculate the optimal timing for light exposure, darkness, melatonin, and sleep based on your specific circumstances. This isn't guesswork - it's science.

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.

Feedback like yours helps us prioritize the right updates—thanks again!
It works!

This app made such a difference on my last trip. I usually struggle with jet lag for days, but following the plan really helped me adjust way faster. easy to use and effective!
Not worth it

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. ☕✈️
Scam app

This is NOT Timeshifter and is trying to confuse unsuspecting customers. Timeshifter should get this off the App Store. The recommendations are useless and ridiculous. I now downloaded Timeshifter and am really embarassed that I was played.
