The feature tracks blood oxygen drops and breathing disruptions over two sleep sessions in a 10-day period, categorizing severity rather than giving a simple binary result. The Galaxy Ring becomes the first commercial smart ring with regulatory clearance for sleep apnea tracking. Support for Galaxy Watch 7 and 8 will be coming later. Samsung has begun rolling out upgraded sleep apnea detection to its wearable lineup, leading with its flagship smartwatches on your wrist and expanding down to your finger. The capability is now reaching users on the Galaxy Watch 9 and Galaxy Watch Ultra 2, alongside an expansion to the Galaxy Ring. This improved sleep apnea function refines how Samsung monitors overnight breathing disturbances, transforming passive tracking into more actionable health data. The rollout follows regulatory clearances from the US Food and Drug Administration (FDA) and South Korea’s Ministry of Food and Drug Safety (MFDS), as announced by Samsung. The approvals allow Samsung to push upgraded sleep apnea detection across both key markets via updates to the Samsung Health Monitor app.
