Store description excerpt
Stop guessing how to beat jetlag. Start using the science. The Jetlag Fix turns decades of circadian rhythms research into a simple, personalized plan for your body clock. Enter your flight, and the app tells you exactly when to seek light, when to avoid it, and when to sleep so your internal clock aligns to your destination faster. WHY LIGHT IS THE ANSWER Your body clock doesn't run on willpower. It runs on light. Light exposure at the right time pulls your clock forward or back. At the wrong time, it pushes it the opposite way and makes jetlag worse. Most travel advice ignores this entirely, which is why most travel advice doesn't work. The Jetlag Fix is built on mathematical models of the human circadian system developed by leading sleep and circadian scientists. It calculates where your body clock actually is, where it needs to be, and the optimal path between the two. WHAT YOU GET Personalised light schedules. Hour-by-hour guidance on when to get bright light and when to stay dim, for the days before, during, and after your flight. Flight-aware planning. Enter your route and the app builds a plan around your real departure and arrival times. Sleep timing that fits your trip. Recommended sleep and nap windows designed to speed adaptation rather than fight it. Pre-travel head start. Begin shifting before you leave so you land already partway adjusted. Clear daily actions. No jargon, no theory to wade through. Just what to do and when. Plans for any direction. Eastward, westward, short hops, and long hauls each need different strategies. The app knows the difference. WHO IT'S FOR Business travellers who need to be sharp on arrival. Holidaymakers who don't want to lose three days of a two-week trip. Frequent flyers, crew, athletes, and anyone who crosses time zones often enough to be tired of feeling wrecked afterwards. BUILT ON REAL SCIENCE Jetlag isn't a vague feeling of tiredness. It's a measurable misalignment between your internal clock and local time, and it affects sleep, alertness, mood, digestion, and physical performance. Circadian science has understood how to correct that misalignment for years. The Jetlag Fix is that knowledge, in your pocket, applied to your specific trip. The app draws on research into individual differences in light sensitivity and real-world light exposure, so the guidance reflects how bodies actually respond to light, not a generic rule of thumb. SIMPLE TO USE Add your flight. Tell us a little about your usual sleep. Follow the plan. That's it. Check the app each day, do what it says, and arrive functioning. WHAT MAKES IT DIFFERENT Most jetlag apps offer generic advice or a countdown timer. The Jetlag Fix models your circadian system directly and adapts to your schedule, your sleep habits, and your itinerary. It also tells you what not to do, which matters just as much. Getting light at the wrong hour can set your adjustment back by a full day. THE PAYOFF Fewer wasted days. Better sleep o
