CardioRing ECG Blood Pressure Smart Ring Medical Grade Dual Core Sleep Blood Oxygen Heart Rate HRV AI Health Tracker

CardioRing — The World's First Dual-Core ECG & Blood Pressure Smart Ring

CardioRing is a medical-grade smart ring that combines a medical-grade ECG sensor with a medical-grade PPG sensor in an industry-first dual-core design (500Hz sampling rate). Wear it on your finger to capture heart electrical signals and pulse wave data for ECG heart-risk screening and blood pressure trend monitoring, backed by AI deep-learning algorithms.

Core Medical Functions

• ECG Monitoring: Unlimited ECG recording with 30-second quick test; AI-ECG automatically analyzes sinus rhythm, atrial fibrillation (AFib), high/low heart rate and other conditions. Reports support cloud storage, PDF export and one-click sharing.
• Medical-Grade Blood Pressure: PTT (pulse transit time) pulse-wave measurement using ECG + PPG sensor fusion and AI deep learning — more accurate blood pressure trend tracking than a PPG-only ring. One simple monthly calibration.
• Blood Glucose Trend (BGEM): AI-driven non-invasive diabetes risk pre-screening.
• Heart Rate & HRV: 24-hour continuous heart rate tracking with HRV.
• Blood Oxygen (SpO2): All-night monitoring with trend chart and low-oxygen alert (normal ≥95%, alert 93-94%, danger ≤92%).
• Respiratory Rate, Skin Temperature & Night Fever Monitoring.

Sleep, Stress & Recovery

• Medical-grade sleep staging (deep, light, REM, wakefulness, sleep onset and duration) with overnight vital signs and a graded sleep score plus improvement guidance.
• Daytime stress monitoring with real-time relief guidance and daily mood support.
• Physical recovery score to balance activity and rest; flexible daily goals for steps, calories and distance.

Sports & Fitness

Multiple workout modes including walking, running, cycling and swimming, for indoor and outdoor scenarios. Each session records real-time heart rate, steps, distance, calories, duration and movement trajectory. Swimming mode recognizes breaststroke, freestyle, butterfly and backstroke, and counts strokes and laps. Outdoor cycling supports GPS route tracking.

Daily Wellness

• Built-in white noise (forest, ocean waves, raindrops, flowing water, train) for mindfulness, relaxation and focus.
• Women's menstrual cycle tracking with a self-developed AI prediction model.
• Shareable sleep diary and health data insights.

Design & Battery

• IP68 waterproof & dustproof — safe for washing, showering and swimming.
• 10+ days of long battery life (light use); wireless fast charging, full charge in about 90 minutes.
• Powered by the NexRing app — lifetime free subscription (iOS & Android).
• 365-day replacement service for the medical-grade sensor (replacement only, no repair).
