Generic jet lag advice is, well… generic. It won’t reduce your jet lag and can actually make it worse. Each traveler and trip is different and requires a personalized approach that takes your sleep pattern, chronotype, flight plan, and a range of personal preferences into account.

Timeshifter® is developed by world-renowned scientists based on the latest sleep and circadian neuroscience. With Timeshifter, you can create your own personalized jet lag plans and arrive at your best.

Timeshifter not only provides advice to alleviate the disruptive symptoms of jet lag such as insomnia and sleepiness, but addresses the underlying circadian disruption by rapidly resynchronizing the circadian clock to the new time zone.

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

All the features you need:

// Practicality Filter™ adjusts advice to the "real world"
// Quick Turnaround® advice for short business trips
// You can start adapting even before your departure
// Notifications offer advice - even without opening the app

Timeshifter is a highly empowering experience, and it requires no special equipment. Just bring a sleep mask and your favorite sunglasses.

Join the community of Timeshifters around the world who demand a better travel experience. Whether you’re traveling for business, going on vacation, or competing in a sports event abroad, the Timeshifter jet lag app can help optimize your performance, enjoyment, and health when traveling.

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!

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!

This app WORKS

My god if you don’t download this app if you are a regular long haul traveller then you have no business being one. I followed the advice given as best as I could (some of it was difficult to do due to flight times) but I tried my hardest to access light and stay in the dark where I was told and I am now day 5 in Sydney having travelled across from the UK and not a SNIFF of jet lag do I have. Last time we came here we were bed bound for two days with hideous tiredness. I have felt the odd moment where I could have perhaps had a nap but honestly they pass as quickly as they come. This app has honestly saved us time feeling sick and tired and all we did was follow the clear instructions on the app. Amazing... Thankyou so much
