About Timeshifter - The Jet Lag App
// Condé Nast Traveler: “Say goodbye to jet lag”

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 (one way or roundtrip) 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.

Two of us use this to change our body time from California to Australia time, about 17 hours difference in time. We found it made a huge difference and we had very little problem once we got to Australia blending right into the normal time there. We would highly recommend it. Our return flight was changed due to the...
Nice app, really worked the first time I used it, I find it kind of expensive (first trip was free) but can't deny it works.
