Timeshifter

I used it on a trip from US West Coast to India. It worked amazingly well and I had insignificant Jetlag. I followed the plan about 90%. Withheld one star as the UI could use some improvements otherwise the plan itself worked very well. I will be using it on all my long-haul trips.

I’ve used this app for many years and it was really terrific, but on the last few trips, it has been buggy to say the least. Today, a day before I’m flying long distance, it wants me to drink caffeine from 9 AM to 11pm. I’ve tried twice to send a chat to tech-support, without any response. maybe someone bought this app, as it is a shadow of what it once was. And that is very sad!

We flew from the war coast of the US to Iceland (+7 hours) and days later went Sweden (+2 more hours). We followed the recs of the app and it worked like a charm! The least amount of jet lag we’ve ever experienced. We felt rested and ready to go and will follow the recs on our return trip too. Highly recommend!

To me, the value in this app is not so much in their insights, which are wise and well-communicated but fairly common sense, as the discipline that the app provides to actually APPLY the insights. Huge help. Minimal jet lag!

I just used this app on my way to Venice. I have gone to Europe several times because my best friend lives in France and have always been affected by jet lag. But, this time, using the app, I did not have any jet lag. I will purchase this app for my trip next year. My husband used it last year to travel and said it was amazing. He is right!! I also used it on the way home from Italy and it worked beautifully! I had no jet lag at all. This app is wonderful!!

I will shout from the rooftops at how well this app worked for me. I spent three weeks in Australia and was dreading coming home and experiencing terrible jet lag. I had friends telling me to prepare for two weeks minimum (14 hour time difference). July 31 I started Timeshifter to begin my return home on August 1. I followed the recommendations 100% and I ended my plan today (August 6) and I have felt very little jet lag. Only one wake up in the middle of the night and plenty of energy coming back to work! I will be using any time I travel outside of the Eastern time zone again!

I tried this app and it really worked. I am a retiree and thought its hard to teach an old dog new tricks. But I did learn! I had a roundtrip to Rome (9 hour difference) and this app was very helpful to reduce any jet lag. I was quite awake and alert upon arrival and return! I happen to have an upcoming trip to China (15 hour difference) and plan on using this so I don’t spend time sleeping while there!

This app works! Following the plan is not difficult. Highly recommend. PHX-LHR. Able to enjoy the trip from Day1.

I’m based in America for school but most of my family is in Japan. I make an effort to go visit them as I can, so have made the trip back and forth from NYC to Tokyo several times over the years. What a difference this app has made! Depending on the time of your flight, the plans can be easier or harder to follow, but if you follow it as closely as you can, you’ll be surprised by the effectiveness.

The app was recommended to me midway through a round trip from Philadelphia to Barcelona and was very helpful in minimizing my jet lag while in Spain and on my return to the states. The app provides clear instructions on when to sleep, consume/avoid caffeine and when to get light. The user interface is a little complex but the realtime notifications are super helpful.
