Timeshifter

Developed by world-renowned scientists. Based on the latest sleep and circadian neuroscience. Used by astronauts and elite athletes. With Timeshifter, you can create your own personalized jet lag plans and arrive at your best and comfort.

The provided evidence supports the general circadian basis of jet lag management: light-dark timing, sleep timing, naps, caffeine, and melatonin are all discussed as tools that can influence adaptation. The app’s approach is consistent with circadian neuroscience, but the product-specific outcome claims are based on company-reported surveys rather than independent clinical trials. Overall, the evidence supports the concept and mechanism more strongly than any precise performance guarantee.
