Timeshifter

With much of international travel this app became indispensable for me. Yes, you would need to follow instructions thoroughly, and it often includes a certain level of hardship. Yes, instructions aren’t always as clear as I would like and lack practical examples of behavior patterns. But if you do it all right, the results will amaze you.

I travel abroad on average once month, sometimes back to back. This app has helped me tremendously adapt to different time zones without stress. Highly recommend

全く時差ボケになりませんでした。全て指示通り完璧に実践する必要はないとアプリにも書いてあり、どうしても従うのが難しい場合も少しだけでもその行動を取り入れさえすれば、しっかりと効果が得られます。 初回は無料だったのですが、次回からも絶対に課金して使いたいと思うアプリです。

時差ボケなく旅行を楽しみたかったので利用しました。 アプリから定期的に時差ボケを防ぐための指示が旅行会社日の3〜4日前か送られてきます。睡眠、カフェイン摂取、光量調整などの行動を指示通りに行うと全くと言っていいほど時差ボケを感じません。 金額的にも大変お手頃だったので、有料版を使いました。高くない旅行代金と貴重な時間をこのアプリによって無駄にせずに済むので高くない買い物です。

I’ve used this app time and time again for many overseas trips and it really helps to reduce jet lag. While it doesn’t get rid of it entirely, I find I am able to get acclimated quicker and have more energy throughout my trip. Highly recommended! Four stars as it is a little pricey for what you get, especially as we’re not traveling as much as we used to.

I have many international business trips, and I have been experiencing severe jet lag every time (e.g. waking up super early morning). After started using this app, I am having much better traveling experience!

I traveled from the east coast of the US to Japan with 9 friends. The time difference between the two locations is 12 hours. I followed the Timeshifter plan with about 85% compliance, and I was the only person in our group with no ill effects from jet lag. I was dumbfounded at how well the app guidelines worked. I have recommended this app to numerous friends—it worked beautifully for me, and I have already added my flights to England for my next trip. I do not intend to travel without it. Thank you for creating this fantastic tool!

This app made the 12 hour time difference completely doable. We followed about 95% of the directions (missed some of the naps) and arrived ready to hit the streets exploring. Not a day wasted trying to recover from jet lag. I could not recommend this app more. We signed up for the annual because we have several trips planned for 2025 and will use it for them all. A trip to Japan who is 14 hours ahead will be a snap with help from this app. I tell everyone who travels about Timeshifter.

I’ve now used it for Lisbon, Japan and Tanzania. I still cannot believe how well it works. I follow it as much as I can. Sometimes I can’t sleep/nap when it wants me too. And I won’t wear sunglasses inside an airport. But I do use caffeine, melatonin and bright lights, etc. I used to have terrible multi day jet lag. Now I can’t even consider myself someone who experiences jet leg. Like at all. It’s pretty magical.

Timeshifter is the single most impactful travel tool I have ever discovered! In the past I have always assumed the first day of a trip to be a wash and planned my return a day early to readjust and be rested for work. With Timeshifter it feels like we gain two extra days of vacation for the cost of a few cups of coffee! For our most recent trip to Europe we arrived in Paris early morning and spent the day wandering the city without any signs of jet lag. On my return I arrived late and followed TimeShifter’s advice to stay up till 1am. I then slept like a baby till my alarm at 7am and woke up well rested and able to dive back into work without feeling jet lagged !
