United StatesCreate highly personalized jet lag plans based on your chronotype, sleep pattern, itinerary, and personal preferences. // Condé Nast Traveler: “Say goodbye to jet lag” // The Wall Street Journal: "Indispensable" // Travel + Leisure: “Game-changer” Travelers are constantly bombarded with bad advice from non-experts and false product claims, resulting in many persistent misconceptions about jet lag and how to alleviate it. It's time to replace the myths with real circadian science: 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 making your jet lag worse. Timeshifter will help you reduce 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.

Really great UX
I really enjoyed this app. The best feature is being able to plug in just flight numbers have everything populate without spending forever manually entering everything. This app was exactly what I was looking for for a trip to Singapore and AUS with crazy long flights and many time changes. I loved how the schedule starts a few days before you leave to ease you in. I found it difficult to follow during the trip and on the way home, but just knowing when to sleep on my first day of 20 hours of flights was great. Even not following it exactly I felt great my whole two week trip.
United StatesWaste of time
Does not help. Don’t waste your money
United StatesWorks
Over all we didn’t have any trouble sleeping, 16hours difference between US and Japan will make you tired etc, but we did not experience any significant jet lag at all. ❤️ I followed the instructions 90% of the time. It worked, I’m very happy with it. Im definitely trying it again in the future with different time zone. Super simple and friendly app.
United StatesThis app helped so much!
I have never left an app review but this app worked so well that I feel compelled to tell everyone! We flew from California to Japan, and on the way there experienced a little jet lag on the first day (mostly owing to our 7 year old who couldn’t follow the plan quite as well), but on the way home I experienced almost zero. I was stunned! Last time I travelled internationally I was a mess for 4-5 days each way. I will absolutely be using this app again. And I will be telling my friends and family!
United StatesTimeshifter is a great app and it works!
I got Timeshifter because I was going to Rome and staying one week. I did not want to waste even one day being out of it. I followed the directions which were simple and had no jet lag. The people I traveled with had very bad jet lag for about two days. It wasn’t just fatigue but headaches, stomach issues, dizziness, and feeling zoned. The app sent me a text when I was to avoid light or be in bright light. It was very easy to follow. Best of all it worked!!!
United StatesI’m sold
I started using this program a couple of years before it became available via an app. To the extent that I follow it, I get excellent results. I use it mostly for vacations. I usually follow the pre-travel program rigorously before outbound travel but not very well before return travel; I give higher priority to enjoying my vacation. Particularly impressive was my experience when I spent 35 hours, and two overnight flights, traveling from Seattle to Botswana. My first afternoon in Botswana I took a game tour with some tourists who were amazed that I had just arrived and was functioning normally. I had gone to Botswana to work and had scheduled a recovery day before starting work. The recovery day was quite unnecessary.
United StatesLife Altering
As someone who is extremely prone to jetlag, Timeshifter was literally life altering. I flew from LA to the UK, and had not one minute of jet lag. I was able to hit the ground running and truly maximize my limited time on UK soil. Super easy to use, this app is now a permanent part of my travel plans. Thank you Timeshifter!!
