We want to facilitate the improvement of people's health

Circular combines the technologies of hardware miniaturization, biological measurements and machine learning to enable people to understand and improve their health as discreetly as ever, on a daily basis. Not everyone recognizes symptoms and in many cases, the underlying causes are not diagnosed.

We want people to take advantage of wearable devices to help them engage with their own health. Taking care of oneself upstream means less disease.

Help us pioneer the way to improved personal health

Circular has developed a range of devices and analytic tools that allows healthcare professionals to track the largest array of data points. By partnering up with health professionals for years, we transformed the way data collection can be made and are giving back to the scientific community through qualified data.
