How QRNT Tracks Your Health

QRNT is a smart ring designed to monitor key health metrics using three integrated sensors: PPG (Photoplethysmography) for optical heart rate and blood oxygen detection, Accelerometer for motion and activity tracking, and multiple NTC thermistors for skin temperature measurement. These sensors work together with proprietary algorithms to provide insights into your well-being, without invasive methods.

All metrics are processed securely on-device or via the app. With QRNT, you’re always in control of your personal health data. We protect your information with secure, U.S.-based storage, keeping it private, safeguarded, and entirely yours. Learn more about our privacy policy.
