Used by astronauts, elite athletes, and top CEOs, Timeshifter is the most advanced jet lag tool available. Travel + Leisure: "This jet lag app will help you adjust to new time zones quickly" The Wall Street Journal: "Indispensable app for business travelers" CNBC: "Innovative new travel app that saves time and money" 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 taking your sleep pattern, chronotype, flight plan, and a range of personal preferences into account. Timeshifter is developed with Harvard Medical School Associate Professor Steven Lockley, Ph.D., and based on the latest research in sleep and circadian neuroscience. 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 Timeshifter algorithm is the most advanced of its kind: // Based on the latest research in sleep and circadian neuroscience // Practicality filter adjusts advice to the "real world" // Quick turnaround advice for short business trips // You can start adapting even before your departure // Notification system offers advice - even without opening the app // Works well across all times zones - even offline and in-flight – When you use Timeshifter for the first time, you will quickly realize how many things you could have done differently in the past. It’s 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 - with this app, you will arrive ready to go. – This app offers in-app purchases.

  • Does not work

    Sorry to say this app does not work. It is largely depending on sunlight exposure which is not possible at night!

    Entered travel details for a trip from Eastern Timezone to Japan and was provided a plan. The plan delivered guidance on when to sleep, seek/avoid light, caffeine, and take melatonin (which I substituted with Tylenol PM without acetaminophen). I followed the plan closely, but didn’t really do anything special with light aside from be aware of light around me and make small adjustments such as opening or closing plane window. I arrived in Japan and actually had energy to explore some the first night there and got a full night’s sleep. My first full day in Japan I felt completely normal despite the 14 hour offset, and the normal feeling persisted for the entire trip. Upon return, I again followed the plan, and had normal energy for work my first day back. Coworkers were actually surprised by my alertness. I’m a very routine oriented person and don’t typically adapt so well to changes. This app is amazing and completely worth the in-app purchase, gave me an extra day of vacation and extra day of productivity upon return. Also very well designed.
  • 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.
  • Works well!

    This app really helped coming back from halfway around the world. I had 35 hours of travel beginning at 1AM. I felt exhausted from a lack of sleep but my sense of time felt normal after my first night of sleep. I will be purchasing the year long subscription to help on trips in the future.
  • $24 Subscription. One free try. That one didn’t work.

    Couldn’t handle a trip from Seoul to DFW to Indy. Expensive unless you’re going to use it a lot!
  • Instant fail

    By Old Man Dancing
    This app failed right out of the box. I started to set up my flight to India and immediately hit their brick wall. For number of stops, it gave me the choices of none, one, or two. I have THREE. I’m sure this app works fine if you’re flying to Cancun for the weekend, or somewhere that you don’t really NEED it. But, if you’re going on a trip where jet lag is a serious problem, this app may prove useless to you.
  • Yes - it’s true - it does work!

    Just did SIN-TPE-SFO-PDX, and can honestly say I had no jet lag! I followed the app’s plan to the tee including all the light changes and use of caffeine. I used 500mcg of Melatonin. I was in the gym lifting heavy and hard the day after I landed and felt awesome! HIGHLY recommend!!! Great job guys!
  • Wow! This really works!!

    Remarkable! I travel monthly and am the worlds worse with jet lag for some reason. My husband bounces back and I spend a week waking up at 3 a.m. I am miserable and functioning poorly. My first trip using TimeShifter had me happily asleep all night from the day I left on my trip and again when I got home. I never had a sleepless or disjointed night sleep the begging of my trip nor upon my return. I am thrilled!!!! Easy to follow and works!!! On a trip to Zimbabwe some years ago I was really out of sync and losing it. Finally turned to sleep meds which are awful too. So groggy. Wish this App had been available sooner. Next big test is in January. Vietnam is a day and 13 hours off my time I believe. Can’t wait to try my TimeShifter then. Customer service is AWESOME by the way. So worth the minimal cost for more enjoyable travel!!!! Thanks for this great travel aid!!!!!!
  • Tripit integration

    Love the app, but love it more if I didn’t have to manually enter all my trip data. All the API’s exist. Get’r’done!
  • Use this app!

    I suffer terrible jet lag even going east with a 3 hour time change. Used this to adjust to a 9 hour time change to Europe and it was great!! Huge difference in how I felt so I could enjoy vacation. Great support with my questions too. Thank you!!
