Unlocking human performance, safety, and health through circadian timing and control
A different kind of time
Time isn’t just hours, minutes, and seconds. There’s a different kind of time — not invented by us or powered by batteries. It’s each person’s internal circadian time, which quietly governs nearly every biological system in our bodies — from sleep and alertness to metabolism and immune function — and can vary significantly between people.
Revolutionary apps
At Timeshifter, we translate complex circadian science into practical, high-impact products that address challenges affecting billions, each using the same core technology. Our first product — a jet lag app — is now the most downloaded in the world. Our second is an app designed to help shift workers improve sleep, health, and quality of life, while enhancing safety and boosting productivity.
The undisputed leader
in circadian technology
Timeshifter is also trusted where circadian control is mission-critical, from space missions to elite sports. As we enter the next frontier of personalized medicine, we’re exploring how Timeshifter can serve as the clock for delivering healthcare aligned with each person’s biology. Our vision is a future where clock time and circadian time live side-by-side.
