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.

Now getting little or insignificant jet lag

As a regular long haul air traveller I was keen to use this App to reduce my jet lag and have now been a subscriber for over 8 months. During that time I have used the App’s programme for 4 return long haul flights involving time zone differences of 4-9 hours. It is not always possible to follow the exact timings of when you need to sleep on planes but I have always followed the advice on caffeine intake and exposure to or avoiding bright lights. I only used melatonin for the last trip as it’s difficult to obtain in the UK . I can safely say it has made a marked difference to the amount of jet lag experienced which was negligible on a trip just done with a time difference of 5 hours, as compared to all of my fellow travellers (not using the App). What I like about the App is that it is based on the established scientific understanding of sleep ( known as chronobiology).in addition, it is personalised for you taking into account your normal sleep habits eg when you usually wake up/ go to bed and how long you like to sleep. Once that’s in the system all you need to do is put in all your flight details of departure and arrival locations with timings , including any stop overs. The App then works out your programme which is displayed as an easy to follow timeline chart with symbols .
I would thoroughly recommend this App to all regular long haul travellers as it has worked for me every time!

THIS IS AMAZING

This app is totally incredible. I have suffered horrible jet lag for the last 20 years, just accepted it as part of being a regular traveler (usual LA TO London route being the worst). I followed this app to a T after putting in my flight details, I started the night before I flew and I had almost 0 jetlag. I went from sometimes feeling jet lag for a month after to having absolutely 0 jetlag symptoms by the 4th day and the only symptom I had the first 3 days was I would wake up at 1am for about an hour and then fall back to sleep blisffuly while sleeping 8.5 hours straight the first three nights - during the right hours for the timezone I was in. So aside from that one hour wake up in the night I had no symptoms. No brain fog, no fatigue, nothing. And by night 4 my sleep is totally back to normal. I did use Melatonin as well for the first time and I also did a red eye flight so maybe both those helped? Either way I will ALWAYS use this app from now on! I can't recommend enough, game changer!

London- LA round trip

I followed the plan very diligently, though with a little scepticism and am more than delighted with the results. As my trip was a short, wedding dress shopping with my daughter who lives in LA, one (5 days), adjusting immediately to local time meant I could take advantage of every moment. When looking at my return Timeshifter plan, I realised I had entered the incorrect flight departure time. I used the Timeshifter chat and had a very quick response, where the problem was resolved by deleting the return journey plan and re-entering the correct flight time.
On the return journey I was not popular with my immediate neighbours when I turned on my reading light. However, I feel it certainly assisted my adjustment to uk time.
Once home, I had to fight against the urge to sleep in early evening, but persevered and had a full night’s sleep and since then have felt completely back on UK time.
I’ll definitely be using Timeshifter again in October for the wedding in LA!
