Jet lag doesn't have to be inevitable, thanks to the science underpinning this great app. By using principles of light exposure and circadian rhythms, TimeShifter's tactics are similar to the ones employed by NASA to help astronauts cope with the disorienting effects of a body clock that's out of sync with the world around them. Cost: The first jet-lag plan is free; subsequent plans are $9.99; annual subscription for unlimited plans, $24.99.
