JET LAG MYTHS VS. CIRCADIAN SCIENCE • Misleading advice on conquering jet lag – often promoted by non-experts or companies lacking real circadian science expertise – not only fails to help travelers but can make jet lag symptoms worse and may even cause harm. • Jet lag CANNOT be fixed with generic sleep advice, exercise, hydration, dietary supplements, special diets, or fasting. None of these approaches will reset a traveler’s central circadian clock quickly to new time zones. • Light is the key time cue to “reset” our circadian clocks, so the correct timing of light exposure and light avoidance, based on the traveler’s chronotype, normal sleep pattern and itinerary, is the only way to adjust to new time zones quickly. If the traveler’s timing is wrong, it will make their jet lag worse.
WHY WE MADE TIMESHIFTER Getting the timing right is both complex and unintuitive. We created Timeshifter to make circadian science accessible and help you apply it to conquer jet lag.
Timeshifter helps you tackle both the underlying cause of jet lag – the disruption of your circadian clock – as well as reduce the disruptive symptoms, such as insomnia, sleepiness and digestive discomfort.
Timeshifter was developed with Dr. Steven W. Lockley. A Harvard Medical School faculty member for over 20 years and former Neuroscientist at Brigham and Women's Hospital, he is an international authority on circadian rhythms and sleep with nearly 30 years of research experience. Dr. Lockley helps NASA astronauts and mission controllers, Formula 1 drivers, NBA players, and Olympic athletes perform at their best.

I have been using the app for the last 6 months. My first 2 trips to Europe, I experienced mild jet lag but the recent one last week was the best where I think I almost didn't have any jet lag. I would highly recommend, literally saves you days in a year not to mention the quality of your energy as you seamlessly adjust if you travel significantly. Takes the thinking out of it.

Timeshifted was very helpful and easy to use. You can see the whole plan in the app and the notifications where helpful for prompts of getting sunlight or getting sleep or caffeine at certain times. I traveled from Colorado to Italy and did not really have any jet lag going or coming back. Which was great because we did a lot of on our trip and I had to get right back to work when I returned. I would absolutely use this app again for travel.

To use the app, you need to create an account and allow notifications. I hate every app that does this.

*Update 6/20/26: Trying this app again with my Pixel 8. I got the first 2-3 notifications, then they stopped coming. Frustrating that they haven't fixed this after at least 4 years. Lots of apps use notifications. Why can't this one? Original Review: Great concept, but notification don't work on Android phones (pixel 8 and 4a in my experience). That means you won't get push notifications telling you when to do what. I used this app 2 years ago and had the same problem.

Nice idea, but completely unusable. It seems to assume that one just teleports to the plane. Advises me to sleep until 9 when I have to be at the airport by 10:30 with a 3h drive...
★☆☆☆☆Jeffery Klein· Jun 27, 2026
Terrible customer service and idiotic limitations my flight plans changed at the last minute bc of a minor emergency. I needed to take a flight 2 days later, but the app assumed I had already left which is reasonable. However, there was no way for me to add a new schedule or delete the previous one. Their Ai bot said the app now thinks I am in the new time zone, so I can't add another trip. The only way to reset the trip was via a customer service report and the wait time was over a day!
