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 that takes your sleep pattern, chronotype, flight plan, and a range of personal preferences into account.

Timeshifter® is developed by world-renowned scientists based on the latest sleep and circadian neuroscience. With Timeshifter, you can create your own personalized jet lag plans and arrive at your best.

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 first jet lag plan is free. After your free plan, purchase individual jet lag plans as-you-go or subscribe for unlimited plans. Timeshifter is a paid service.

All the features you need:

// Practicality Filter™ adjusts advice to the "real world"
// Quick Turnaround® advice for short business trips
// You can start adapting even before your departure
// Notifications offer advice - even without opening the app

Timeshifter is 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, the Timeshifter jet lag app can help optimize your performance, enjoyment, and health when traveling.

Introducing Timeshifter 2: We have listened to our timeshifters, and worked tirelessly to design an even better experience. Every traveler will benefit from this update, but our frequent timeshifters are going to be extra happy.

Let's dive into the enhancements you'll find in the update:

* Multi-city trips: Going beyond one-way and round trips, you can now add complicated itineraries with multiple destinations.

* Unlimited stopovers: We all prefer to fly nonstop, but if you can’t, you can add as many stopovers as needed.

* Unlimited trips: Tired of adding one trip at a time? Now, you can add all of your future trips into Timeshifter.

* Flight editing: Did your plans change? No problem. Update the departure or arrival times, or replace the impacted flights.

* Quick trip entry: No more cumbersome entering of all the flight details. Just enter the date and flight number.

* Auto-merge of overlapping timeshifts: Arriving back home just to leave again right away? Timeshifter will automatically take any unfinished plans into consideration.

* Improved user experience: New navigation menu, contextual guidance, and much more.

As always, if you have any feedback or run into issues, please use our live chat in the app. We love to talk.
