If you wake up tired after a full night in bed, or a partner has mentioned loud snoring or pauses in your breathing, you may have wondered what is going on. Samsung's wearable tools now include a feature designed to flag possible signs of one common cause: sleep apnea.
What sleep apnea is
Sleep apnea (a condition where breathing repeatedly pauses or becomes very shallow during sleep) can leave you feeling worn out even after a long night. Samsung's feature does not diagnose it. Instead, it watches for patterns in your body signals during sleep and points out when those patterns might suggest a problem worth discussing with a doctor.
What changed in the update
Samsung says the earlier version of this feature was the first of its kind for a wearable device when the U.S. Food and Drug Administration (FDA) authorized it in February 2024. The updated version, according to Samsung, analyzes your vital signs during sleep in more depth. Instead of only giving a general risk result, it also shows how much breathing disruption it detected.
Samsung also says this is the first time sleep apnea risk detection has come to a smart ring. The Galaxy Ring is a small, lightweight band worn on a finger, and Samsung notes it's comfortable enough to wear all night.
How the feature works
- It runs through the Samsung Health Monitor app. The feature lives in this app on a compatible Galaxy phone and wearable.
- It needs only a little data. You need two nights of valid readings within a 10-day period. Samsung says that's enough to get useful information.
- It is meant for on-demand use. You choose when to use it rather than it running as a constant alert.
- It is for adults. Samsung says the feature is intended for users 18 and older.
- It is not for people already diagnosed. Samsung says people who have already been diagnosed with sleep apnea should not use it.
Samsung says the Galaxy Watch 9, running Wear OS 7.0 or higher, is supported now. It says support for the Galaxy Watch 7 and 8 will arrive through future software updates.
Wrap-up
Samsung presents this update as a way to help people spot possible early signs of sleep apnea and take charge of their sleep health. It's a useful signal, but it is not a medical test and it doesn't replace a clinician's diagnosis or treatment. Today, check whether your Galaxy device is on the supported list, and if you've noticed loud snoring or daytime tiredness, write down what you've observed so you have something concrete to share with your doctor.
