Travelers are constantly bombarded with misguided anecdotal advice from non-experts on how to alleviate jet lag. It's time to replace the myths with tested and validated circadian science.

Timeshifter is the leader in circadian technology, uniquely offering the only scientifically-validated advice proven to quickly adjust you to new time zones and alleviate jet lag symptoms.

In your brain, you have a 24-hour circadian clock that regulates nearly all of your biological functions. Jet lag is caused when your sleep/wake and light/dark cycle shift too quickly for your circadian clock to keep up. The only way to reduce jet lag quickly is by shifting your circadian clock to the new time zone.

Light is the most important time cue for “shifting” your circadian clock. Light exposure and avoidance, at the right time, will significantly accelerate your adaptation. Seeing or avoiding light at the wrong time — as often recommended by non-experts — will shift your circadian clock the wrong way – away from your new time zone – making your jet lag worse.

Timeshifter helps you eliminate jet lag by addressing the underlying cause – the disruption of your circadian clock – as well as alleviate the disruptive symptoms, such as insomnia, sleepiness and digestive discomfort.

All the features you need:

Circadian Time™:
Advice is based on your body’s clock

Practicality Filter™:
Adjusts advice to the "real world"

Quick Turnaround®:
Automatically detects short trips

Pre-travel advice:
Start adjusting before departure

Push notifications:
View advice without opening the app

Timeshifter’s benefits are well established. Based on ~130,000 post-flight surveys, 96.4% of the travelers who followed Timeshifter's advice did not struggle with severe or very severe jet lag. When NOT following the advice, there was a 6.2x increase in severe or very severe jet lag, and a 14.1x increase in very severe jet lag.

Your first plan is free. After your free plan, purchase individual plans as-you-go or subscribe for unlimited plans. Timeshifter is a paid service.

Works GREAT!

I just used this app for the first time for traveling from the USA west coast to Greece, a 10 hour difference. It’s easy to follow the recommendations - the plan before I left started 2 days ahead, telling me to go to bed progressively earlier by a couple of hours, and to avoid or seek light by no more than 2-3 hours difference than when I would anyway. It also told me when to drink or avoid caffeine, but I usually don’t do coffee, and mostly ignored that advice without problems. The only part that was a bit difficult was sleeping on the plane, which I’m very bad at, plus the plan wanted me to sleep until only an hour or two before landing which is basically impossible since that’s when the lights go back on and people start getting ready to arrive. But I took melatonin (as the app advised) and a Unisom and did manage to sleep several hours regardless. Once I landed the plan continued for another 3 days, but again with nothing crazy or challenging. I can’t say that I had no jet lag at all (I still felt like my body was vibrating at odd times), but the difference really was remarkable regardless; there never was a time when I felt like a zombie or wanted to sleep or stay up when everyone around me would be normally doing the opposite. I’m definitely going to keep using this app. I also love the pricing structure - the first trip is free and then is pay per trip which is very sensible.

I’m sold! This app is amazing!

Recently flew from JFK-HKG-ICN-HKG-JFK. I was worried because I usually get pretty hard with jet-lag, even on flying shorter distances - and I really had to hit the ground running when I arrived. Well I can honestly say that I never experienced any jet-lag effects during my trip - or upon my return. . My colleagues were all complaining and they would hit a wall at around 3-4pm and complain that they woke up in the middle of the night and could not go back to sleep. Meanwhile I was bright eyed and bushy tailed. One of the people I was visiting in Seoul, even commented on how refreshed I looked, given I had flown almost 20 hrs the previous day. I followed the app as close as I could. I also utilized those blue light blocking glasses when I was supposed to be avoiding light - but couldn’t completely control my environment. Regarding melatonin, I find that most people take too high of a dose. I would start with a 2.5 mg dose prior to sleep. If I woke up at least 4 hrs before I planned to - and felt I would have trouble falling back to sleep, I would take another .5 to 1.0 mg dose and would fall right back to sleep. On my outbound 16 hr flight to Hong Kong, my flight departed at 9am - and the app instructed me to sleep the first 7 hrs of the flight. Taking the low dose melatonin each time I woke up (approx) every two hrs - really helped. Will definitely subscribe to the annual plan and rely on this for all future long-haul trips.

Follow it & REALLY works - recommend to All

I came across the name of this app in an article and have since come across it in more online articles since downloading and using it. I was doing some simultaneous research on my upcoming trip to Europe (from the US) and also on helping my mom reset her circadian rhythm, as it’s become a major quality of life issue for all of us. I downloaded it onto my iPhone, for this first free trip, And was determined to use it as an experiment because I remember in the past having terrible jet lag upon arrival in Europe. I admit that I followed it to a T and started following suggestions on the app starting four days before departure. I know from experience that I was in a much better state of mind upon arrival. I’ve recommended this to friends and family, particularly for the distance that you have to travel, specially for those that travel often and or for business purposes. I really appreciate the simplicity and beauty of the app with the visual cues and also the ability to read more and learn why and how things work. Because I plan to do more traveling in the coming years I will definitely purchase use of the app. I have them for their review online and found more information and research behind the app and I’m sharing this with my mom who really needs to reset her circadian rhythm but has no guidance on that. Kudos to an exceptional app that is extremely user-friendly!
