New Delhi, Oct. 23 -- Wearables have shrunk from wrist companions to subtle, sensor-packed rings. The latest wave, led by the Oura Ring 4, Samsung Galaxy Ring, and Ultrahuman Ring Air, goes beyond step counts. They track recovery, stress, and overall wellness with AI-driven precision. With passing time, smart rings are redefining how people manage health data; Quietly, and continuously.

A smart ring is a minimalist fitness tracker that fits on your finger but works like a health lab. It measures heart rate, SpO2, sleep, and recovery using built-in biometric sensors. Made from lightweight titanium or stainless steel, these rings sync with your phone for real-time analytics. Some even handle gestures or contactless payments.
