Samsung's Galaxy Ring can now flag signs of sleep apnea, a first for a smart ring

Samsung announced on Tuesday, Nov. 3, 2026, that its upgraded Sleep Apnea feature is now available on Galaxy Watch and Galaxy Ring, making Samsung the first company to bring sleep apnea risk detection to a smart ring.

Sleep apnea is wildly underdiagnosed, and the barrier is usually that nobody wants to sleep in a lab wired up like a science project. A ring you already wear to bed and a two-night check lowers that bar a lot. The fine print matters, though: this finds people who should see a doctor, it doesn't replace the sleep study, and it only works inside Samsung's phone-and-wearable world.

Samsung's updated Sleep Apnea feature, in the Samsung Health Monitor app, is now available on Galaxy Watch and Galaxy Ring. Samsung says this makes it the first company in the world to offer sleep apnea risk detection on a smart ring. Sleep apnea is a condition in which breathing repeatedly stops or becomes very shallow during sleep. The availability claim is Samsung's.

The updated feature received U.S. Food and Drug Administration clearance in July 2026, and Korea's Ministry of Food and Drug Safety, the MFDS, has approved it as well. Clearance, here, means the FDA allowed this version to be sold. Samsung says it will keep expanding availability to more countries. Those lines are Samsung's.

What is new is the algorithm, the set of steps the software follows. It analyzes vitals during sleep in more depth and now reports the level of breathing disruptions detected, an estimate of how many disruptions happened each hour. That goes beyond the earlier yes-or-no style of risk assessment. Those lines are Samsung's.

It needs as little as two nights of valid data within a 10-day period. Two nights inside ten days is the minimum Samsung states. That requirement is Samsung's.

It is an over-the-counter, software-only mobile medical application on a compatible Samsung Galaxy wearable and phone. Over the counter means a person does not need a prescription to use it. It is intended to detect signs of moderate to severe sleep apnea in users 18 and older. It is not intended for people already diagnosed with sleep apnea, and it does not replace diagnosis or treatment by a clinician. A clinician is a doctor or another licensed person who can make that call. Those limits are Samsung's.

On the watch side, Samsung's footnote says the feature is available on Galaxy Watch9 running Wear OS 7.0 or higher, with Galaxy Watch7 and Watch8 support coming through future software updates. Wear OS is the software the watch runs. Those lines are Samsung's.

Samsung's original Sleep Apnea feature received FDA De Novo authorization in February 2024, the first of its kind for a wearable. De Novo is the FDA route for a device that has no earlier product of the same kind to be compared against. That history is Samsung's.

The Galaxy Ring sells from $399.99 at Samsung.com in the United States. That starting price is Samsung's store price.

Jongmin Choi, head of the Health R&D Group in Samsung Electronics' Mobile eXperience Business, said: "We are giving people the tools to help spot possible early signs of sleep apnea and take charge of their wellbeing." That quotation is his.

In plain terms, a Galaxy Ring or Galaxy Watch can now flag signs of moderate to severe sleep apnea from as little as two nights of sleep, and report an estimate of breathing disruptions per hour. The FDA cleared the update in July 2026, and Korea has approved it. It is a reason to see a doctor. It is not a diagnosis, and it does not replace a sleep study.
