This jet lag app is the first of its kind, that calculates a response that is tailored to your individual body clock. Part 1 of this app calculates how much of a morning person, night owl or something in-between you are. Part 2 gives you the times when to go to sleep and when to wake up, according to your starting point and destination. Using scientifically validated drug-free techniques, you can minimise the impact of jet lag on your performance when you travel, and enjoy your trip overseas.
