The Smart Sleep Ring is a finger-worn tracker that monitors heart rate, blood oxygen and sleep quality continuously, and also counts steps, distance and calories. It adds a shake-to-shoot remote camera trigger and an app that lets you view family members' health data. It is IP68 waterproof and comes with a small charging case rated for 10-15 refills. Its 3.2 rating from 200 buyers suggests the concept appeals more than the execution; dedicated sleep rings from established brands are generally judged more accurate and better supported.
