This is a lightweight titanium smart ring that tracks heart rate, sleep, calories and skin temperature, and it is waterproof to 10 ATM. At 2.3 g it is light enough to wear overnight, which is when most of its useful data is collected. It suits people who want passive health tracking without a watch on their wrist. Against better-known smart rings it covers the core metrics but has fewer sensors and no GPS, so it is a basic tracker rather than a full fitness device.
