This 50G pulse oximeter ring features newly upgraded chips that deliver 1 percent accuracy, allowing real-time tracking of blood oxygen (SpO₂), pulse rate, and body movement directly from your fingertip. Made from soft, breathable, low-sensitivity silicone, it’s ergonomically designed for all-night comfort and won’t disturb sleep. The lightweight ring fits fingertips 1.57–2.36 inches and includes a rotatable display for left- or right-handed wear. USB-C charging provides up to 10 hours of continuous use on a full charge.
Simple to use, the ring connects automatically via Bluetooth when you open the app—no complicated setup required. The free app supports multi-user profiles, unlimited data storage, detailed reports, and customizable alerts for abnormal readings, all while working offline to protect your privacy. During Bluetooth disconnection, the ring can store up to 21 hours of data and sync automatically later. Ideal for sleep tracking, sports, and aviation use (not for medical diagnosis).
