Samsung's FDA-cleared screening now runs on the ring and Galaxy Watch9 in the US. Here's what you need, what the result means, and its limits.
Samsung has turned on its upgraded sleep apnea screening in the US, and for the first time it works on the Galaxy Ring as well as the Galaxy Watch9. The FDA cleared this version in July. Instead of a simple yes or no, it counts breathing disruptions per hour of sleep and labels the result mild, occasional or frequent.
To use it you need a Samsung Galaxy phone, the Samsung Health Monitor app, and two nights with at least five hours of sleep inside ten days. It's for adults who haven't already been diagnosed, and Samsung stresses it doesn't replace a doctor.
If you snore or wake up tired, it's a free, easy first step to take to a doctor.
Yes. As of November 3, the answer to “does Galaxy Ring track sleep apnea” finally flipped from no to yes: Samsung switched on its upgraded sleep apnea check for the ring in the US, and the company says that makes the Galaxy Ring the first smart ring to carry an FDA-cleared, over-the-counter tool that looks for signs of the condition. The same upgraded check also landed on the Galaxy Watch9.
Why it matters: sleep apnea, where your breathing keeps stopping and starting at night, often goes unnoticed by the person who has it. Samsung cites US National Sleep Foundation figures of about 25% of men and 10% of women in the US living with it, many without knowing. A ring you’d actually keep on in bed could be the nudge that gets someone to book a proper test. There are rules, though, and one of them trips people up.
Both, but in different ways. The ring had never offered a sleep apnea check before, so this is new for Galaxy Ring owners. Galaxy Watch owners have had a simpler yes-or-no version since Samsung won De Novo authorization from the FDA in February 2024 (De Novo is the route the FDA uses for a new kind of low-risk health product with nothing similar already on sale).
The new version got its own FDA clearance in July, and Korea’s food and drug regulator has approved it too. It lives in the Samsung Health Monitor app, not the main Samsung Health app, so that’s the place to look once your ring or watch has updated.
The path here was long. Samsung first got the watch feature approved at home in Korea in 2023, added the FDA authorization the following February, and has since spread the original version to 84 countries. The ring had to wait for the reworked algorithm, which needs less data to reach an answer.
It also works on demand. You start a check when you want one, rather than having it watch over every night in the background.
Here is where things stand on the watch side in the US:
Samsung says it has no plans to pull the older yes-or-no feature, so if your watch isn’t on the upgrade list, nothing you have today goes away.
The check is picky about setup, and missing one requirement means no result at all. Based on Samsung’s own fine print, you need:
That two-night rule is the one to plan around. A single good night won’t produce a reading, and short nights don’t count. If you know your week has a couple of late finishes, pick two calmer nights inside the ten days and wear the device for the whole night.
Comfort is part of Samsung’s pitch for the ring. It is light enough that people who hate sleeping with a watch on their wrist are more likely to keep it on, which matters for a test that needs full nights of data.
The old feature gave you a flag: signs of moderate to severe sleep apnea, or none. The upgraded one goes further. An AI model counts how often your breathing is disrupted for each hour you sleep, then sorts the result into one of three levels: mild, occasional or frequent.
In plain terms, each disruption is a moment when your breathing gets shallow or pauses long enough to matter. A few now and then is common. Lots of them, night after night, is what leaves people drained even after eight hours in bed, and it is the pattern doctors want to catch.
That per-hour count is closer to what a doctor’s sleep study measures, which is why Samsung frames the result as something to bring to an appointment. It can turn a vague “I’m always tired” into a specific number of disruptions an hour that a clinician can act on.
Just as clearly, Samsung says the feature is no substitute for a diagnosis or treatment from a qualified clinician. A frequent result is a reason to see a doctor, and a mild one isn’t a clean bill of health if you still snore loudly or wake up gasping.
If you already own a Galaxy Ring or a Galaxy Watch9 and a Galaxy phone, this is a free check you can run this week. Update the Samsung Health Monitor app, wear the device through two full nights, and take the result to your doctor if it comes back occasional or frequent.
If you’re shopping for a sleep tracker specifically for this, the rivals matter. Oura, the best-known smart ring, does not have FDA-cleared sleep apnea detection, though it does track overnight disturbances that can hint at breathing problems. Samsung and Oura are also in a legal fight over smart ring patents, with a preliminary ruling expected soon, so keep an eye on that before you buy.
Samsung has also reworked its Sleep Coaching feature so it needs less data before it starts giving advice. If the apnea check comes back clear but you still sleep badly, that coaching is the next free tool to try on the same ring or watch.
And if you’re in the UK or Canada, hold off for now. The upgraded check is live in the US and approved in Korea, while Samsung says only that it will expand to more countries over time. The original watch feature reached 84 countries after its first approvals, so a wider rollout is likely, but no date has been given for either market.
Not yet. Samsung has launched the upgraded ring feature in the US and cleared it in Korea, and says more countries will follow without naming dates.
No. The feature needs a compatible Samsung Galaxy phone and the Samsung Health Monitor app.
At minimum two nights. Each night needs five or more hours of sleep, and both have to fall within a ten-day window.
