Wait 5 sec.

Credit: Kaitlyn Cimino / Android AuthorityCircular’s smart ring is getting a new Immunity Index that measures your defense against diseases.It accounts for your vitals and gives you a rating on a scale of 0–8.The feature is rolling out to the companion app for the first-gen Circular Ring and will be available for the Ring 2, which is expected to be available soon.Even though the smart ring market is still niche, the entry of big players like Samsung with its Galaxy Ring has set it into motion. Besides already established brands like Oura and (relatively) new entrants like Samsung, a host of smaller brands are looking to benefit from this momentum. Circular, one of these brands, is making noise with unusual (for a smart ring) features such as blood pressure and non-invasive sugar level monitoring right from your finger. While we await its newer generation, Circular’s existing model is gaining new insights that predict before you fall sick.The first-generation Circular Ring now takes into account vital health metrics, including HRV or Heart Rate Variability, resting heart rate, irregular breathing patterns during sleep, and variations in skin temperature. This data is consolidated into an Immunity Index, which, Circular says, is designed to indicate a user’s “readiness to fight off diseases.”
