Great App!

This works perfectly if you follow it well. Sometimes I have to work the day after travel with long time shifts and it helps sooo much. Thank you!!

Super helpful!

I’m so glad I gave Timeshifter a go, the app is very user friendly, you pop your flight details in and it automatically sets a plan for the few days before / after your flight.

Totally love the app, but..

How wonderful would it be if you imported from TripIt or flighty?

Not Practical to Use

If you have a job, responsibilities, pets, and/or children, this app is difficult to follow. The timing for going to bed and waking up is nearly impossible to comply with. I’m glad I could try this for free for the first trip before committing.

Cracked the code on jet lag with Timeshifter!

Several tech industry execs and top tier road warriors told me Timeshifter is their secret to managing jet lag. A few months later I joined a project that requires bi-weekly trips from California to Japan. I tried the app on my first trip and managed to avoid jet lag almost entirely. I’ve been using Timeshifter religiously ever since (4 roundtrips) and feel like I have a super power. Timeshifter has cracked the code on jet lag. It is a game changer for anyone who travels regularly across time zones.

Timeshifter creates personalized jet lag plans based on scientific principles of circadian rhythms. It helps you adjust your body's internal clock to new time zones by providing specific advice on when to expose yourself to light and when to avoid it, aiming to reduce symptoms like insomnia and sleepiness.

How does Timeshifter use circadian science?

The app leverages the understanding that light is the primary cue for your body's circadian clock. It provides tailored recommendations for light exposure and avoidance, timed precisely to help your internal clock synchronize with your destination's time zone, addressing the root cause of jet lag.

Your first jet lag plan is provided for free with no commitment. After that, you can choose to purchase individual plans as needed or opt for a subscription to get unlimited plans for all your travels.

What kind of advice does the app offer?

The app offers practical advice that considers your real-world schedule, thanks to its Practicality Filter™. This includes guidance on light exposure, sleep timing, and pre-travel adjustments to help you prepare for your journey and minimize jet lag symptoms.

Who is Timeshifter intended for?

Timeshifter is designed for healthy adults aged 18 and older who frequently travel across time zones. It is not intended for pilots and flight crew on duty. The app aims to help users conquer jet lag and improve their travel experience.
