Timeshifter Jet Lag

Conquer jet lag with Timeshifter Jet Lag, the app that applies circadian science to reset your body clock and eliminate travel fatigue. Instead of following generic myths about sleep and exercise, this app uses proven light-exposure timing—the only scientifically validated method to adjust your circadian rhythm to new time zones quickly.

Your internal circadian clock regulates your sleep-wake cycle and your body's response to light and darkness. When you cross time zones, this clock falls out of sync with your destination, causing jet lag symptoms like insomnia, daytime sleepiness, and digestive discomfort. Most common jet lag advice fails because it doesn't address the root cause: resetting your circadian clock. Light exposure at precisely the right moments is the key to rapid adjustment, and timing is everything—get it wrong and you'll actually worsen your jet lag.

Timeshifter does the complex math for you. The app generates highly personalized jet lag plans based on your chronotype, normal sleep patterns, and travel itinerary. Using Circadian Time™ technology, your advice is tailored to your body's actual clock, not generic recommendations. The Practicality Filter™ adjusts suggestions to fit real-world constraints—not every recommendation will work for your flight schedule, so the app prioritizes the actions that matter most. For short trips, Quick Turnaround® automatically detects when you don't need a full adjustment plan, saving you unnecessary effort.

Start optimizing before you leave. Pre-travel advice helps you begin shifting your rhythm days before departure, so you arrive closer to local time already. Push notifications deliver your daily guidance without requiring you to open the app—perfect for staying on track during busy travel days.

The results speak for themselves. Among nearly 130,000 post-flight surveys, 96.4% of users who followed Timeshifter's advice 80% or more reported no severe jet lag. Those who ignored the recommendations experienced a 6.2x increase in severe jet lag and a staggering 14.1x increase in very severe cases. Major publications including The Wall Street Journal, The New York Times, and Condé Nast Traveler have endorsed the app as a game-changer for travelers.
