It has never been easier to check on your health



The infrared heart rate sensor integrated in the ring combined with the Circular app allows you to read your heart signals in real time and continuously. The Circular app indicates whether your heart rate shows signs of atrial fibrillation, a severe form of cardiac arrhythmia, or if the rhythm is sinus, which means that your heart is beating at a steady rate.



It is easier than ever to follow your vital signs. This is a real advancement for such a small portable device, because it allows you to share crucial data with your doctor and gain peace of mind and comfort. Thanks to automatically generated trends, you can now track the evolution of your health data over time.



Kira makes reports and correlations for you which are exportable inside of the app or on your soon to come Circular dashboard. Whether sleep apnea trends over the past couple of months or wellness correlations, you can easily get advice from professionals based on your data.

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. Moreover not everyone recognizes the symptoms. This is why, 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.
