Definitely helped

Compared with previous trips, our jet lag was much improved after using the app. We had to adjust some timings a bit due to travelling whilst in India the day before our flight home, but all in all it worked quite well for us. Would definitely consider using it again but not sure we would pay the one off price.... it seems a bit too steep. Sorry x

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. I’ll definitely be using Timeshifter again in October for the wedding in LA!

First experience using Timeshifter

Very cool UX!! App looks great and user interaction is fantastic! Got a try-out coupon at Websummit 2018. Regarding taking sleep during a flight I think it is impossible to sleep in the first and last hour, so suggest to modify the algoritm for this. Also I expected to have some food advice, in my experience it enhanced my adoption to the new timezone when I modify the times and amounts of food I take. All the best with your further developments!

Works great!

I’ve used the TimeShifter app for several trans-Atlantic trips, and the recommendations from the app have helped me greatly reduce jet lag in both directions. Follow the guidelines as much as possible and get the reward of more energy and active time - instead of restless hours in bed and dizziness during the day.

NO jet lag!

Timeshifter is the best product by far that I’ve used for fighting jet lag. On a recent trip from NYC to Tokyo, ZERO jet lag in both directions. Using it for upcoming trips to Australia, Barcelona, Milan. Recommended it to all my colleagues. Try it!

Wow! This really works!!

I am adding to my original review which follows. We went to Vietnam and Timeshifter again worked amazingly well. The time was almost exactly the opposite of our time. We were only gone 8 days. Timeshifter had me sleeping all night the first night in Vietnam and functioning great from the first full day there. Upon my return I slept well the first night and never experienced jet lag. I could not be more thrilled!!

Game changer

I’ve always felt like a zombie travelling from Canada east to Europe. Heard about this app in the Globe and Mail. It’s fantastic. It lays out a plan a few days in advance and after flight. Felt great on arrival and I adapted effortlessly for my vacation.

Beat jet lag the scientific way!

In a period of 17 days I had - Singapore, Japan, Australia,Singapore, Atlanta (USA) and back to Singapore (home). I used this app to a tee on the singapore - Atlanta - Singapore portion. I had very little jet lag on the way over to the USA and NONE on the way back to Singapore. This is a first in traveling all my working life ..... brilliant, brilliant! If you travel beyond 3+ hours in time difference this app will really help ... highly recommended!!

Max jet lag? No problem!

I just got through a return trip from Ireland to New Zealand thanks to the Timeshifter app. I have done the trip a few times and was amazed at how much easier it went, under guidance from Timeshifter. Obviously jet lag doesn’t get any worse than that, but I was somehow able to function immediately on local time at both ends. Highly recommended.

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.


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. 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.

Great idea, great UI/UX!

Love the design and can’t wait for my trip in December to see how the concept actually works in real life, and how the reminders work. One tiny thing for now: I would definitely pay for the app IF the flight details can be auto filled in upon entering only flight date and number. Anyway, will update my review once my trip is over.
