Description

From the listing uploaded by “appupdater”.

Timeshifter applies the latest circadian science to adjust you quickly to new time zones. Make jet lag history with highly personalized jet lag plans, based on your chronotype, normal sleep pattern and itinerary. // Condé Nast Traveler: “Say goodbye to jet lag” // The Wall Street Journal: "Indispensable" // Travel + Leisure: “Game-changer” // New York Times: “Timeshifter is as good as it’s going to get." // CNBC: "Saves time and money" // WIRED: "Will help reset your [circadian] clock” // Lonely Planet: "Incredible" // Prevention: “One of the best apps according to doctors” JET LAG MYTHS VS. CIRCADIAN SCIENCE Misleading advice on conquering jet lag — often promoted by non-experts — not only fails to help travelers but can make jet lag symptoms worse and may even cause harm. It’s time to replace the myths with real science. Generic sleep advice, exercise, hydration, grounding, dietary supplements, special diets, or fasting won’t solve jet lag because they don’t "reset" your circadian clock to new time zones. THE REAL SCIENCE BEHIND REDUCING JET LAG // In your brain, a circadian clock helps manage the regular rhythm of your day. // Jet lag is caused when your sleep/wake and light/dark cycles shift too quickly for your circadian clock to keep up. // Light is the key time cue to “reset” your circadian clock, so the correct timing of light exposure and avoidance is the only way to adjust to new time zones quickly. If your timing is wrong, it will make your jet lag worse. WHY WE MADE TIMESHIFTER Getting the timing right is both complex and unintuitive. We created Timeshifter to make circadian science accessible and help you apply it to conquer jet lag. Timeshifter helps you tackle both the underlying cause of jet lag – the disruption of your circadian clock – as well as reduce the disruptive symptoms, such as insomnia, sleepiness and digestive discomfort. KEY FEATURES // Circadian Time™: Advice is based on your body’s 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 PROVEN RESULTS Based on ~130,000 post-flight surveys: // 96.4% of users who followed Timeshifter's advice 80% or more did not struggle with severe or very severe jet lag. // Travelers who did not follow the advice experienced a 6.2x increase in severe or very severe jet lag, and a 14.1x increase in very severe jet lag! TRY IT FREE Your first jet lag plan is free—no commitment required! After your free plan, you can choose to purchase plans as-you-go or subscribe for unlimited plans.
