Summary
Samsung says its updated Sleep Apnea feature is now available on Galaxy Ring and Galaxy Watch after US FDA clearance and approval by Korea’s MFDS. The feature reports insights into breathing disruptions detected during sleep; it is intended to flag signs, not replace clinical diagnosis or treatment.
Samsung Electronics says its updated Sleep Apnea feature is now available on Galaxy Ring as well as Galaxy Watch, following US Food and Drug Administration clearance in July 2026 and approval from Korea’s Ministry of Food and Drug Safety (MFDS) in October. Announced on November 3, 2026, the update adds insights into the level of breathing disruptions detected during sleep, beyond the earlier version’s sleep-apnoea risk assessment.
The feature runs through the Samsung Health Monitor app. Samsung describes it as an over-the-counter, software-only mobile medical application that operates with a compatible Galaxy wearable and phone. The company says it is the first to offer sleep-apnoea risk detection on a smart ring.
What the feature measures
Sleep apnoea involves interruptions or reductions in breathing during sleep. Samsung says the updated algorithm analyses a user’s vital signs while they sleep and provides insight into the level of breathing disruptions detected. The announcement does not specify which vital signs the algorithm uses, so the feature’s output is best understood as a screening signal rather than a complete clinical assessment.
The feature is intended to detect signs of moderate to severe sleep apnoea in people aged 18 and older. It is designed for on-demand use, requiring two nights of valid data within a 10-day period. Samsung says the relatively small amount of monitoring data needed allows users to gain insights from as little as two nights in that period.
The company says the feature is available on Galaxy Watch 9 running Wear OS 7.0 or higher. Support for Galaxy Watch 7 and Watch 8 is planned through future software updates. Samsung also presents the ring as an alternative for overnight monitoring, alongside the watch.
What the regulatory status means for users
The updated feature’s US clearance and Korean approval are distinct from the earlier regulatory milestone Samsung cites: the original feature received FDA De Novo authorization in February 2024. Samsung said that authorization was the first of its kind for a wearable designed to detect signs of moderate to severe sleep apnoea.
The intended use sets important boundaries. The feature is not meant for people already diagnosed with sleep apnoea, and Samsung says it should not replace traditional diagnosis or treatment by a qualified clinician. A detected disruption can provide a reason to discuss sleep health with a healthcare professional, but the app is not presented as a standalone diagnosis.
Adding the ring extends the feature to another wearable form factor, while retaining a watch option. For people who use compatible Samsung devices, the two-night monitoring requirement may make periodic checks less dependent on wearing a watch every night. The practical value of the output still depends on interpreting it within the feature’s stated screening purpose.
