Jetlag is a travel and navigation application designed for iPhone users, specifically aimed at helping individuals acclimate to new time zones before their travels. By inputting simple parameters a few weeks prior to departure, users receive a personalized schedule that gradually adjusts their bedtimes, wake-up times, and meal times. This proactive approach is intended to minimize the discomfort associated with jet lag.

The app's user-friendly interface allows for easy tracking of progress and adherence to the tailored schedule. With its focus on gradual adjustment, Jetlag aims to enhance the travel experience by ensuring users adapt smoothly to their destination's time zone, ultimately allowing them to enjoy their stay without the hindrance of jet lag.
