Established in 2017, the French start-up Circular designed a smart ring that improves users’ health and wellness. Following its success at the CES 2022 in Las vegas, the Circular Ring will be available for presales on February 27th on Circular website (delivery between April and June 2022). The company’s goals are to “democratize personal health” for worldwide users and to meet the growing demand for health wearables*.

Circular smart ring embarks sensors capable of detecting 142 metrics including heart rates variability, blood oxygenation, breathing rate, body temperature and more. The ring connects via Bluetooth to your iPhone or Android device, day and night.

Compared to competitive wearables, the Circular ring does not provide just raw data but personal insights thanks to the accompanying app that includes a personal assistant. Circular correlates every day and night metrics to give personalized recommendations that help users in making good decisions and responding to their body signals in a healthier way: better sleep, physical activities and heart recovery, health proactive monitoring to alert on diseases such as sleep apnea, etc.


Initially, Circular is targeting the B2C market and will soon be aimed at professionals’ target (insurance companies, medical and health establishments, etc.). Orders mainly concern European countries (France, Germany, UK and Italy) and the United States, and also Australia, Hong Kong and Singapore.

Among the company’s perspectives: controlling other connected objects with the ring, building partnerships with French luxury brands, targeting health professionals within 2 years and a second fundraising.
