How it works

Four steps to beating jet lag

Avion Shift turns the science of circadian rhythm shifting into a simple, actionable plan you can actually follow.

Add your flights

Enter your departure and arrival details. Avion Shift handles layovers, connections, and time zone math automatically.

Get your shift plan

Avion generates a day-by-day schedule starting a few days before you fly — sleep windows, light cues, meal timing, and more.

Follow the reminders

Timely notifications tell you exactly what to do and when. No guesswork, no spreadsheets — just follow the plan.

Land feeling great

Your circadian rhythm arrives at your destination on time. Wake up refreshed, not wrecked.

What travelers say

Jet lag, defeated

Real stories from people who stopped dreading the time zone change.

I fly NYC to Tokyo four times a year for work. Avion Shift is the first app that actually made a difference. I followed the plan and felt normal by day two.

Frequent flyer, finance

Timeshifter wanted $25/year. Avion does the same thing for free and the UI is way better. Looks like Flighty, works like magic.

Priya S.

Product designer

The light exposure reminders are the key thing I was missing. I always knew about melatonin but the light timing is what actually fixed my jet lag.

Flew London to LA with my family. Kids were adjusted in two days instead of a week. Highly recommend for anyone traveling with children.
