BodiMetrics Circul Sleep and Fitness Ring

CIRCUL is an oxygen ring, that can be worn comfortably day and night as a continuous blood oxygen and heart rate monitor. Compare this with a traditional bulky finger oximeter that covers most of a finger, may have a cord attached, and cannot be worn comfortably. A common finger oximeter does not allow for continuous, round-the-clock SpO2 monitoring. Additionally, studies show that a a pulse oximeter that wraps around your finger may be less accurate, especially while wearing nail polish.

As as fitness ring, you can monitor your heart rate and blood oxygen levels (SpO2) during workouts, as well as count steps with its built-in pedometer. As a health ring, you are able to monitor oxygen saturation and heart rate throughout normal daily activities, including sleep, workouts, regular daytime activities, and working. As a sleep ring, nighttime blood oxygen monitoring ensures that oxygen levels and heart rate are within normal ranges. As a sleep monitor, CIRCUL will save your results and upload them to the cloud, so you can see the long-term trends of your blood oxygen levels at night. The unique sleep tracker report shows you your sleep stages, including awake, REM sleep, and deep sleep.
