OMG, it works! When you input your departure time, arrival time, and duration of flight, the this app app shows you acupressure points that you hold when you arrive at your destination, and voila! Your body’s internal clock is somehow re-set to the local time zone. I don’t understand how it works, but it actually WORKS! Last month, I used it going to/from the U.S. and Australia, and I suffered Not One Ounce of jet lag, in either direction! Uplift is pure genius and will benefit anyone who is changing time zones! Worth every penny, and a lot more. In the past, I flew into Australia two days before any event, so that I could recover from the jet lag. The expense of those extra two days is no longer needed! I cannot say enough good things about this app. BTW, I am a baby boomer and this is the first time I’ve ever reviewed an App.
