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.

By knowing our circadian time, and being able to control it, we can optimize our performance, health, and safety in ways never before possible. We can minimize jet lag and bring back those lost days. We can reduce the negative effects of shift work. We can prepare to be at our best when needed, even when we would otherwise not be at our physical or mental peak. Soon, we will also be able to time our medication better, and prepare our body for medical treatments to improve clinical outcomes.

At Timeshifter, we are leading the way in making all of this possible — integrating circadian science into our everyday lives and bringing its benefits to people who need it the most. Timeshifter translates complex circadian science into practical, high-impact products that address circadian challenges affecting billions.

Our vision

A future where clock time and circadian time live side-by-side and people align with their circadian rhythms to unlock performance, safety, and health.
