SkyZen mobile app by IATA helps travelers to combat jet lag and improve their sleep patterns.

SkyZen app does so by monitoring the person’s health and wellbeing before, during, and after a flight.

In order to use the app, travelers must enter their flight number, class of travel, and date. Using the collected and stored data, the app will then update passengers on their flight activity and provide them with ways to minimize jet lag while crossing time zones.

It’s currently available for free at iTunes and will be created in Apple Watch versions soon.
