About this app
Overview, features and application details
Timeshifter builds a personal jet lag plan from circadian science. Enter your flight and sleep habits, and it tells you exactly when to seek light, sleep, nap, or drink caffeine.
Timeshifter doesn't plan your trip — it plans your body clock. Give it your flight details and usual sleep pattern, and it builds a schedule to beat jet lag.
The plan is specific: when to get bright light, when to avoid it, when to sleep, when a nap helps, and when caffeine is smart or a bad idea. No vague tips.
It's built on real circadian research and used by astronauts and elite athletes. You can even pre-adjust your sleep before the flight so you land closer to the new time zone.
For long-haul flyers who want to land functional, it's in a league of its own.
