Mike Massimino, former NASA astronaut.

"Astronauts are always looking for anything that can give extra bandwidth, focus, and energy for the crucial moments. It's critical to avoid costly mistakes and can even affect our survival. When I was an active astronaut at NASA, I used the same science-based circadian algorithm as Timeshifter is deploying in their app. When on missions, it helped me prepare for launches at odd hours, and to perform at my best on orbit. On earth, it helped me to eliminate jet lag when traveling to train in time zones as disparate as the U.S., Japan and Russia.

I can’t recommend Timeshifter enough.”
