Jet lag, gently planned
Move your body clock toward local time.
A personal plan that tells you when to sleep, seek light and have coffee — starting days before you fly.

Airports, dates and times.

Follow your plan
A day-by-day timeline that starts before you fly and follows you through your stay.
Your body clock runs on light.
Light at the right moment shifts your internal clock forward or back. Light at the wrong moment pushes it the wrong way. ChronoFlow times it for you, together with sleep and caffeine.
Read the science →- Sleep 22:00 – 06:30
- Seek bright light 06:30 – 09:00
- Avoid bright light after 20:30
- No caffeine after 13:00
Travellers who slept on it
“The plan for my Tokyo trip was clear and easy to follow.”
“I check it on the plane in the dark. It's the only app that's actually readable at 3am.”
“The light timing was the thing I'd been missing. Simple and calm.”
