About

Jetlag Away turns your flight into a day-by-day plan for light, sleep and caffeine, so your body clock arrives when you do.

How the plan is built

A flight has two facts that decide almost everything about the adjustment that follows: which direction you are travelling, and how many hours your body clock has to move. Jetlag Away takes the departure and arrival times you enter — each in the local time of its own airport — and works out both.

From there it builds a day-by-day schedule of the three things that actually shift a body clock: when to seek light and when to avoid it, when to sleep, and when caffeine helps rather than hurts. Eastward travel is harder than westward, because advancing the clock is harder than delaying it, and the plan reflects that rather than treating the two as mirror images. You can tell it how aggressively you want to adjust, and it will spread the same shift over more days or fewer.

Reminders for each step are scheduled on your phone, not sent from a server. If you check in during the trip and report how you actually slept, the plan can be rebuilt around where you really are rather than where the original schedule assumed you would be.

Who publishes it

Jetlag Away is published by Hojtech, in Denmark. Hojtech is the data controller for the app and this site, and the terms are governed by Danish law.

There is one address for everything — support, privacy questions, and account deletion for anyone who has already removed the app:support@jetlaga.com. A person reads it.

How it is paid for

By the people who use it, and by nothing else. Jetlag Away shows no ads and sells nothing to anybody. There are two paid options — Single Trip as a one-time purchase, and Frequent Flyer as a subscription — both handled entirely by the App Store or Google Play, so payment details are never seen or stored by us. A short free window lets you build a real plan before deciding.
