Best smart rings for sleep and everyday tracking
Best for: The broadest sleep, readiness, and wellness insights
Oura Ring 5
Oura Ring 5 is the strongest overall choice if you want a polished app that turns overnight readings into readable sleep, readiness, activity, and stress trends. PCMag rated it 4.0/5 and found it comfortable, with accurate sleep and stress tracking; its review unit lasted 10.5 days in that test. WIRED reports a 6–9-day typical battery range, while the Amazon listing describes about a week, so treat battery life as dependent on size, settings, and use. The bigger cost issue is membership: after the included first month for new members, it is $5.99 per month or $69.99 per year. WIRED says that without membership, the app limits access to Readiness, Activity, and Sleep scores. Oura also does not replace a watch for detailed live workout data or GPS. Oura Ring 5 uses its own sizing standard, different from regular jewelry rings and earlier Oura generations, so start with the Ring 5 sizing kit. PCMag’s Oura testing WIRED’s review and membership details Forbes Vetted’s hands-on notes
- PCMag found detailed, accurate sleep and stress tracking with useful short- and long-term guidance
- Works with iPhone and Android, and the app is organized around sleep, readiness, and activity trends
- A thin, lightweight design is intended for comfortable overnight wear
- Most detailed insights require an ongoing membership after the included trial month
- Automatic workout detection can be inconsistent, and the ring lacks built-in GPS
- Ring 5 sizing differs from standard jewelry sizes and previous Oura generations, so size it before ordering
Best for: Affordable sleep tracking without a required app subscription
RingConn Gen 2 Air
RingConn Gen 2 Air is the budget pick for shoppers who want sleep, heart-rate, activity, and stress tracking without paying for a monthly membership. PCMag tested its battery at 10.5 days and found its sleep data detailed and accurate in testing, but it noted some inaccurate heart-rate readings, slow app syncing, and minimal exercise tracking. It works with iPhone and Android. RingConn says the Air model does not include the sleep-apnea monitoring feature found on the more expensive Gen 2, so do not confuse the two. Amazon’s listing was $199 with a new offer when checked. The ring uses its own size scale; RingConn recommends a sizing kit and wearing the sample ring overnight before confirming a size. PCMag’s RingConn Gen 2 Air test WIRED’s subscription-free pick RingConn’s official specifications and fit guide
- No required monthly subscription for standard health and sleep features
- PCMag measured 10.5 days of battery life and found its sleep tracking detailed in testing
- Works with iPhone and Android and costs less than Oura Ring 5 or Samsung Galaxy Ring
- PCMag noted some inaccurate heart-rate readings and slow app syncing
- Exercise tracking and AI insights are less detailed than the strongest competitors
- The Air version does not include RingConn Gen 2’s sleep-apnea monitoring feature
Best for: People already using Samsung Galaxy phones and Samsung Health
Samsung Galaxy Ring
Galaxy Ring is a reasonable ecosystem pick if you already use an Android phone and prefer Samsung Health. PCMag liked its lightweight design, battery life, and no-fee app, but found some accuracy issues in testing and recommends it mainly for Samsung users. It works with Android, not iPhone. Some features, including Energy Score insights, Wellness Tips, and snore tracking, require a compatible Samsung Galaxy phone, Samsung Health, and a Samsung account. PCMag measured 6.5 days on its largest-size test unit; Samsung advertises up to seven days depending on size and use. There is no monthly app fee. Take extra care with the Amazon listing: when checked, the linked page showed 3.0/5 from more than 1,500 ratings and a third-party seller, with substantial durability complaints in customer reviews. Verify the seller, return window, and one-year U.S. manufacturer warranty before buying; consider Samsung or another authorized retailer if those terms are unclear. Use Samsung’s sizing kit and keep the sample ring on for at least 24 hours because the ring sizes are not standard. PCMag’s Galaxy Ring findings Samsung’s official product and sizing guide
- No monthly app subscription, with health and sleep information shown in Samsung Health
- Lightweight design and a charging case that can provide extra charges between outlets
- Samsung Galaxy phone owners can access additional Galaxy AI wellness features
- Android only; it is not an option for iPhone users
- Some AI insights and snore tracking require a compatible Samsung phone and Samsung account
- PCMag reported test-accuracy limitations, and the linked Amazon page had mixed durability feedback and a third-party seller when checked
What to check before buying a smart ring
- Get the brand’s sizing kit before choosing a size. Smart-ring sizes can differ from normal jewelry sizes and from one brand or generation to another. Wear the sample for a full day and night; fingers can change size, and a poor fit can make the ring uncomfortable or interfere with readings.
- Add membership fees to the purchase price. Oura provides the richest software here, but the annual fee adds up over time. RingConn Gen 2 Air and Samsung Galaxy Ring do not require a monthly fee for standard app features.
- Check phone compatibility before ordering. Oura and RingConn support both iOS and Android. Samsung Galaxy Ring requires Android, and some of its signature Galaxy AI insights need a compatible Samsung handset.
- Choose based on overnight comfort and the data you will actually use. Smart rings do not have screens, built-in GPS, or the same live exercise detail as many wrist trackers. If you mainly want pace, route maps, or on-the-spot workout stats, a watch may be a better fit.
- Treat sleep stages, readiness scores, heart-rate readings, and cycle estimates as wellness information, not a diagnosis. They are derived from sensor signals and should not be used alone to make medical decisions. Samsung says its heart-rate features are not intended for medical use, and its cycle tracking is not contraception.
If you are not sure whether you will keep wearing a ring overnight, start with the subscription-free RingConn Gen 2 Air or try a sizing kit before purchasing. The ring that feels comfortable enough to wear consistently is more useful than one with features you rarely open.
