Reduce jet lag with personalized plans based on the latest sleep and circadian science. Timeshifter creates a plan for every flight and time zone, tailored to your chronotype, sleep pattern, itinerary and personal preferences. Used by NASA astronauts, F1 teams, NBA players, Olympic athletes and frequent travelers - and rated "as good as it's going to get" by The New York Times. - The Wall Street Journal: "Indispensable" - Condé Nast Traveler: "Say goodbye to jet lag" - WIRED: "Will help reset your [circadian] clock" - Travel + Leisure: "Game-changer" WHAT YOU GET Jet lag plans that show exactly when to seek light, when to avoid it, when to sleep and when to nap, and how to use melatonin (optional) and caffeine correctly (optional) - hour by hour. PROVEN RESULTS Based on ~130,000 post-flight surveys: - 96.4% of travelers who followed their plan avoided severe jet lag entirely. - Travelers who ignored the advice were 6.2x more likely to experience severe jet lag - and 14.1x more likely to experience very severe jet lag.

KEY FEATURES - Circadian Time™: advice timed to your circadian clock - Practicality Filter™: adjusts advice to the "real world" - Quick Turnaround®: automatically detects short trips - Pre-travel advice: start adjusting before departure - Push notifications: view advice without opening the app JET LAG MYTHS VS. CIRCADIAN SCIENCE Jet lag cannot be fixed with generic sleep advice, exercise, hydration, dietary supplements, special diets or fasting. None of these reset your circadian clock quickly to a new time zone. Light is the key time cue that resets your circadian clock. Individually-timed light exposure and light avoidance - based on your chronotype, your normal sleep pattern and your itinerary - is the only way to adjust to a new time zone quickly. Get the timing wrong and jet lag gets worse. Getting that timing right is complex and unintuitive, which is why generic advice fails. Timeshifter works as your jet lag calculator and planner, doing that timing for you. WHY WE MADE TIMESHIFTER We built Timeshifter to make circadian science accessible and help you apply it to reduce jet lag. It targets the underlying cause of jet lag - the disruption of your circadian clock - and reduces the symptoms that come with it, including insomnia, daytime sleepiness, fatigue and digestive discomfort. Timeshifter was developed with Dr. Steven W. Lockley, a Harvard Medical School faculty member for over 20 years and former neuroscientist at Brigham and Women's Hospital. He is an international authority on circadian rhythms and sleep, with more than 30 years of clinical research experience in humans, and works with NASA astronauts and mission controllers, F1 teams, NBA players, national soccer teams and Olympic athletes. Whether you are crossing one time zone or ten, on a long-haul flight or a quick turnaround, Timeshifter gives you a jet lag plan built for that trip.
