After some years of international travel, we've found a way to reduce jet lag using intentional sleep/wake timing.

We apply patterns used in NTP to gradually guide your body's natural sleep rhythm to the new time zone, all without adding losing precious time at home or at your destination.

The general idea is that we apply an 8h leap smear to your body clock. For instance:

A flight from LHR → SFO has an 8h time difference. By gradually sleeping in and staying up later over a ~56h period, you can avoid missing out on life on both sides of the flight.

What pricing models should we try using for this kind of app?
