Land already on local time

Updated 2026-08-17

Eight time zones is roughly eight days of feeling wrong, if you leave it alone. Most of that is avoidable, and none of it requires anything exotic — just doing ordinary things at the right hour.

What Ray does with your flight

You give it the route and the departure. It works out:

Which direction is cheaper — advancing 10 hours or delaying 14, priced in nights rather than hours
How fast you personally shift — an early bird and a night owl get different plans for the same flight
How many nights fit before you go — and what to do with the rest

Then it gives you one instruction at a time:

Get bright light — or keep it dim, on the mornings when light would push you the wrong way
That was the last coffee — six hours before the bedtime you’re aiming at, not the one you currently keep
Melatonin, 0.5 mg — five hours before bed, the timing that moves a clock rather than the one that makes you drowsy
Lights out — a little earlier or later each night, at a pace you can actually follow

It tells you when it can’t help

If your flight is in two days and the shift needs eight, Ray says so before you start, then shifts what it can and finishes in the destination’s daylight. A plan that quietly pretends two days is enough isn’t worth following.

The flight itself gets a plan

Set your watch at the gate. Sleep on board only if it’s night where you’re going — otherwise you’re spending the sleepiness you need to land with. On arrival, light or no light depending on the local hour.

After you land

Most apps stop at the airport. The days after arrival are when the majority of the adjustment happens, so Ray keeps going: the same cues, now in destination time, until your clock has caught up with the wall.

Your first trip is free — the whole plan, every cue, no card.
