This is a stainless steel smart ring that tracks heart rate, blood pressure, blood oxygen, sleep stages, steps and calories, and pairs over Bluetooth 5.1. It is rated IP68 and 5ATM, so it can stay on in the shower or pool, and it adds a remote camera shutter. It suits people who want round-the-clock health data without a watch on their wrist. Against rivals like Oura and Ultrahuman, it claims more sensors on paper, but it is a generic model with no named brand, app ecosystem or independent accuracy testing behind it.
