NexRing smart ring—medical-grade titanium, IP68 waterproof, tracks sleep, blood oxygen, heart rate, HRV, stress, and exercise; non-invasive blood glucose monitoring.

NexRing Smart Ring — Medical Grade Health Monitoring on Your Finger

NexRing is a slim, titanium smart ring that wraps around your finger to deliver 24/7 medical-grade health monitoring. Fingertip capillaries are richer and more stable than the wrist, so heart rate, blood oxygen and other vital signs are measured with greater accuracy (>98% heart rate, >99% blood oxygen). Comfortable enough to wear day and night, NexRing turns every finger into a personal health manager.

Comprehensive Vital Sign Monitoring

• Real-time heart rate and heart rate variability (HRV) monitoring
• Blood oxygen (SpO2) all-night continuous monitoring with trend chart and sleep hypoxia alert
• Respiratory rate, skin/finger temperature changes and energy expenditure
• Stress & pressure monitoring across four stages with active stress-relief guidance
• Blood glucose trend assessment (BGEM) — AI-driven non-invasive diabetes risk pre-screening
• Automatic measurement every 5 minutes, or on-demand via the mindfulness feature

Professional Sleep Monitoring & Guidance

Accurately tracks light sleep, deep sleep, REM, wakefulness and disturbance time, monitors overnight heart rate, blood oxygen, HRV and respiratory rate, then grades each session with personalized, data-driven recommendations to help improve sleep quality.

Sports & Activity

• Multiple sports modes: walking, running, cycling and swimming, for indoor and outdoor scenarios
• Swimming mode recognizes breaststroke, freestyle, butterfly and backstroke, and records strokes, laps and distance
• Outdoor cycling with GPS route tracking, real-time speed, distance and calorie data
• Flexible daily goals: steps, activity calories and distance, with a body recovery index
• Body recovery & vitality score that reflects your physical recovery status

Mindfulness & Wellness

• Women's menstrual cycle tracking with a self-developed AI model that predicts cycles from temperature and hormonal changes
• Health assessment report and health data sharing with family and friends
• Remote camera control and ring search (long-range Bluetooth, up to 70.8 m)

Equipped with advanced medical-grade photoelectric (PPG) sensors and an intelligent algorithm that filters finger motion and adapts to different skin tones for reliable data. Heart rate accuracy is greater than 98% and blood oxygen accuracy is greater than 99%.

Design & Comfort
