A titanium smart ring that tracks sleep and heart rate from the finger, where readings are steadier than from a wrist band that shifts at night. Titanium keeps it light and resistant to scratches, so it wears like plain jewelry. It suits people who want passive health tracking without a screen or a watch on their wrist. Against rivals like the Oura Ring and Ultrahuman Ring Air, it covers the core sleep and heart rate basics; the trade-off is that a screenless ring gives less feedback on the spot and depends on its app.
