Added a couple of checks to warn if "From Timezone" is set to something other than your device's time zone setting
Does jet lag get you down every time you travel across time zones?
Are your sleep patterns off the chart?
Researchers at Stanford University think they have a solution. They've found that brief, frequent flashes of light while you sleep resets your circadian rhythm. An hour of intermittent light flashes while sleeping shifts your "sleep" clock by 2-3 hours. Jet Lag Buster leverages this cutting-edge research to provide similar flashes (Camera Permission is required!).
The App: Use dropdowns to select your travel time zones; the app will calculate the flash profile. Override it, if required. If flying east, set flashes for early in the morning (just prior to waking); if going west, set flashes for the period just after you fall asleep.
Set it up on the night prior to your flight, then wake up ready to take on the world! Go get 'em, tigress.
