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"

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.

Ratings and Reviews
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.
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.
It really works!
I travel a lot and there are all sorts of tricks folks recommend to manage jet lag - I was looking for something that was actually proven in an research type of way (I’m a technical guy).
I tried Timeshifter on my recent trip from Houston to Guam since I was crossing dateline - i plugged in my flight schedules and dates for the trip and it gave me a nice detailed plan when steps to take each day (including days prior to travel and after return). It also sent me me regular notifications of each step while I was on the trip
What I found was that if you follow the recommended sleep times, light, and caffeine intake/avoids - it really made jet lag a non-event. I didn’t quite follow it religiously - I might miss the sleep times by an hour or so and light recommendations are sometimes not easily accomplished BUT even with this effort I found myself easily adjusting to time zones and more importantly the return home was really easy.
My colleagues were all dragging about and saying I’m so tired - I was like I’m not - let’s work!
So I guess you can called me a true believer in timeshifter and will use it in my long trips always.
PS I asked several questions along the way and I always go a response from them very quickly - that’s nice
