Regular rhythm
Open Heart Rhythm and hold the ring with the index finger of your other hand.
Sit, rest your hands, breathe normally. Movement is what ruins a recording.
The ring records an ECG-quality trace while a countdown runs on screen.
A classification in plain language, saved with your symptoms and activity at the time.
Circular is not intended to diagnose, treat, cure or prevent any disease, and is not for use in an emergency.
The dual PPG sensor integrated in the ring combined with the Circular app allows you to read your heart signals and blood oxygen 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.
Circular's recovery, sleep and health is based on the parameters calculated from heart rate (HR), heart rate variability (HRV), resting heart rate (RHR) and breathing rate (BR)– we sample heartbeats selectively, making it more reliable and accurate. From mental stress analytics to circadian cycle analytics, we offer a complete suite of ready to read, accurate metrics.
Kira makes reports and correlations for you, that are exportable inside of the app and on your soon to come Circular dashboard by exporting your clinically accurate heart and health data from the app to share with your provider, you can get better care and health outcomes.
It is easier than ever to measure your vital signs, continuously. 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.
What the exported report carries
Signal quality is printed alongside the result, so a clinician can see what the recording was worth.
Cross correlations
A ring can be worn anytime. By increasing the wearing time, Circular can cross correlates the user's day and night data with machine learning.
Powerful
Circular provides advanced and personalized insights on your heart health, your current energy, on how to improve your sleep and how to optimize your physical activity.
Better data quality
A ring is firmly attached to the finger, which increases raw measurements accuracy.
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.
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.
No. It is a single-lead recording designed to catch signs of atrial fibrillation and give you something concrete to bring to a clinician. A hospital ECG uses twelve leads and a trained reader.
Export the report and speak to a clinician. If you feel unwell — chest pain, breathlessness, fainting — treat it as an emergency and call your local emergency number. The ring is not for emergency use.
We recommend people aged 40+ to do a measurement every month if you are healthy. Do more if you have heart symptoms, high risk factors, or a family history of heart disease
Yes. Heart rate, HRV, breathing rate and blood oxygen are monitored continuously, and Vital Alerts tells you when a limit you set is crossed.
Usually movement, a loose fit or cold hands. Sit still, rest both hands on a surface, and try again — the app would rather say nothing than guess from a poor trace.
No. ECG readings, continuous monitoring, alerts and exportable reports are included with the ring, permanently.
