For a smart ring for fitness tracking, the Oura Ring 4 is my best overall pick in this lineup because it is the clearest match for shoppers specifically seeking Ring 4, while the listed Ring 5 versions offer an alternative for buyers comparing generations. The Milavan Smart Health Ring and BIEMHA Smart Ring stand out as non-Oura options, though their features and app experience should be checked carefully before choosing. The main tradeoffs are familiar hardware and ecosystem versus a different brand, alongside fit, finish, and whether the ring supports the tracking you actually need. The listings include many color-and-size variations, so a product name alone does not tell the whole story. Read on for the full breakdown and a practical way to choose.

Key Takeaways
- Oura Ring 4 listings dominate this roundup: the Silver options in sizes 8, 9, 10, and 11 and the Stealth size 12 share a model family, so choose among them by fit and finish rather than assuming size changes tracking capability.
- Ring 5 is a distinct comparison, not a proven upgrade here: its Gold and Silver listings span sizes 7 through 10, but the supplied product details do not establish how its sensors or software compare with Ring 4.
- Size variation is the most visible difference across Oura listings: the same color and model appear in multiple sizes, making accurate fit checks more useful than choosing by listing order.
- Non-Oura alternatives widen brand choice but add verification work: Hitienx, Milavan, and BIEMHA differ from the Oura-heavy group, so check app compatibility, supported measurements, and return terms before committing.
- Finish is a personal choice, not a fitness feature: Gold, Silver, Stealth, and Pink give buyers different looks, while this roundup does not establish that color changes tracking performance.

More Details on Our Top Picks
Hitienx Ceramic Smart Ring 4 for Women, Pink, Size 9
The Hitienx Ceramic Smart Ring 4 makes sense for fitness-minded buyers who want everyday sleep and activity tracking without an ongoing membership. It records heart rate, HRV, blood oxygen, steps, calories, and activity, with 180+ sport modes for users who want more activity labels than a basic daily tracker. Compared with the Oura Ring 4, its clearest advantage is avoiding a monthly subscription; Oura offers a broader health-tracking ecosystem, while Hitienx keeps the feature set and ongoing costs simpler. Its lightweight ceramic design and charging case suit overnight wear and travel, but the ring itself lasts only 3–5 days per charge. Check the sizing carefully before ordering, and note that the no-display design means you’ll rely on the app to view your results.
Pros:- Tracks sleep, heart rate, HRV, blood oxygen, steps, calories, and activity.
- Offers more than 180 sport modes for varied workouts.
- No monthly subscription is required.
- Lightweight profile and charging case support overnight wear and longer stretches between outlets.
Cons:- Battery lasts 3–5 days per charge without the charging case.
- Sizing should be checked before ordering to reduce the chance of a poor fit.
- No display; recorded information is viewed through the companion app.
Best for: Buyers who want sleep, wellness, and activity tracking across many sport modes without paying for a recurring app membership.
Not ideal for: People seeking Oura’s broader health-tracking ecosystem, longer per-charge battery life, or a ring size they can confidently select without checking the sizing guidance.
- Color:Pink
- Size:9
- Material:Ceramic band; stainless steel case
- Water resistance:IP68; listed depth of 164 feet
- Battery life:3–5 days per charge; approximately 30 days with charging case
- Sport modes:180+
- Compatibility:iOS and Android smartphones
- App and display:QRing; no display
- Metrics tracked:Blood oxygen (SpO2), heart rate, HRV, sleep, steps, calories, and activity
Our verdict“Choose Hitienx for broad everyday tracking and no recurring membership, but choose the Oura Ring 4 if its wider health-tracking ecosystem matters more.”
Oura Ring 5 Smart Ring, Gold, Size 8
The Oura Ring 5 is the stronger fit for buyers who want their ring’s health data connected to a wider digital routine. Its 50+ health metrics cover sleep, activity, stress, and heart health, while support for more than 40 app integrations gives it more connective reach than the Hitienx Ceramic Smart Ring 4. A 6–9 day battery range also means fewer charging interruptions than Hitienx’s 3–5 days per charge. The tradeoff is an ongoing membership after the first month for new members, so its richer app experience comes with a continuing commitment. The gold titanium build is lightweight, but the stated size should not be treated like a standard jewelry size: use the Oura Ring 5 Sizing Kit before choosing, since sizing differs from earlier Oura generations too.
Pros:- Tracks more than 50 health metrics, including sleep, activity, stress, and heart health.
- Connects with more than 40 apps.
- Battery life is listed at 6–9 days.
- Lightweight titanium construction.
Cons:- Membership requires a subscription after the first month for new members.
- The separate Oura Ring 5 Sizing Kit is recommended because sizing differs from standard rings and previous Oura generations.
Best for: People who want extensive health tracking and plan to connect ring data with several compatible apps.
Not ideal for: Buyers who want to avoid recurring membership costs or prefer sizing from a familiar jewelry-ring measurement.
- Color:Gold
- Size:8
- Material:Titanium
- Health metrics:50+
- Battery life:6–9 days
- App integrations:40+
- Included membership:First month for new members
- Membership after included month:Subscription required
- Sizing:Use Oura Ring 5 Sizing Kit; sizing differs from standard jewelry rings and previous Oura generations
Our verdict“Pick this Oura Ring 5 if app connections and broad health tracking matter enough to justify membership and a dedicated sizing step.”
Oura Ring 5 Smart Ring, Gold, Size 7
For someone who wants an Oura Ring 5 and expects to keep it on through swimming or other water exposure, this gold size 7 listing provides a clear specification: water resistance to 100 meters. It pairs that with more than 50 health metrics and 6–9 days of battery life, making it a more health-focused choice than the Hitienx Ceramic Smart Ring 4, which emphasizes 180+ sport modes and subscription-free use instead. The titanium construction is described as scratch-resistant, and the Oura app supports iOS and Android. The costs and fit requirements remain real tradeoffs: new members get one month included, then need a subscription, and the sizing kit is recommended because Oura Ring 5 sizing differs from standard rings and earlier generations. Choose it for water-ready tracking, not for avoiding ongoing app costs.
Pros:- Water resistance is specified to 100 meters.
- Tracks more than 50 health metrics.
- Listed battery life is 6–9 days.
- Titanium design is described as scratch-resistant.
Cons:- Membership requires a subscription after the first month for new members.
- A sizing kit is recommended because the sizing differs from standard rings and earlier Oura generations.
Best for: Swimmers and active users who want Oura’s health tracking in a titanium ring specified for water resistance to 100 meters.
Not ideal for: Buyers who do not want a post-trial membership subscription or who need to select a ring using standard jewelry sizing.
- Model:Oura Ring 5
- Color and size:Gold, size 7
- Material:Titanium
- Battery life:6–9 days
- Health metrics:50+
- Water resistance:100 meters
- Connectivity:Bluetooth
- Supported app:Oura App for iOS and Android
- Membership:First month included for new members; subscription afterward
Our verdict“Choose this Oura Ring 5 size 7 for water-ready wear and broad health tracking if membership and dedicated sizing are acceptable.”
Oura Ring 4 Smart Ring, Gold, Size 7
The Oura Ring 4 is the most balanced choice here for someone who wants a fitness tracker that also follows sleep, stress, heart health, and women’s health. Its 50+ health metrics give it a broader wellness brief than the Hitienx ring’s more workout-mode-focused approach, while up to eight days of battery life supports regular wear with fewer charging pauses. It also works with iOS and Android and is specified for water resistance up to 100 meters. Compared with the Oura Ring 5 listings, this model’s stated battery life reaches up to eight days rather than a 6–9 day range, so the figures overlap rather than show a clear battery advantage. The main compromise is membership after the included first month for new members; check sizing with the Oura kit before ordering.
Pros:- Tracks more than 50 health metrics, including women’s health and stress.
- Up to eight days of battery life.
- Water resistance is specified up to 100 meters.
- Compatible with iOS and Android.
Cons:- Membership costs extra after the included first month for new members.
- Sizing differs from standard jewelry rings, so a sizing kit is recommended.
Best for: Fitness and wellness trackers who want one ring for activity, sleep, stress, heart health, and women’s health across iOS or Android.
Not ideal for: People who want to avoid a membership subscription after the first month or who prefer sizing that matches standard jewelry rings.
- Model:Oura Ring 4 Smart Ring
- Color and size:Gold, size 7
- Material:Titanium
- Battery life:Up to 8 days
- Water resistance:Up to 100 meters
- Compatibility:iOS and Android
- Connectivity:Bluetooth
- Health tracking:Sleep, activity, stress, heart health, women’s health, and more; 50+ metrics
- Membership:First month included for new members; subscription afterward
Our verdict“Choose the Oura Ring 4 for a broad fitness-and-wellness profile and cross-platform support if you accept its ongoing membership and sizing process.”
Oura Ring 5 Smart Ring, Silver, Size 7
This silver Oura Ring 5 keeps the same broad tracking focus as the gold Oura Ring 5 options, but gives buyers who prefer a cooler-toned finish a distinct choice. It tracks 50+ health metrics, works with iOS and Android, and offers 6–9 days of battery life, so it is better suited to ongoing wellness monitoring than the Hitienx Ceramic Smart Ring 4 if Oura app integrations are a priority. Its IP68 water resistance supports everyday wear around water, and the listed integrations extend beyond the Oura app. The tradeoffs are familiar within the Oura lineup: a membership subscription follows the included first month for new members, and sizing needs care. Unlike the Hitienx listing, this is not a no-subscription option, so the silver finish—not a different tracking package—is the main reason to pick it over the gold variants.
Pros:- Tracks over 50 health metrics.
- Battery life is listed at 6–9 days.
- IP68 water resistance and lightweight titanium construction.
- Works with the Oura app and more than 40 integrations on iOS and Android.
Cons:- Membership subscription is required after the included first month for new members.
- A separate sizing kit is required to find the right fit.
Best for: Buyers who want Oura Ring 5 tracking and app integrations in a silver finish, with iOS or Android compatibility.
Not ideal for: People who prioritize a no-subscription tracker or want a different feature set from the gold Oura Ring 5 listings.
- Color and size:Silver, size 7
- Material:Titanium
- Battery life:6–9 days
- Metrics tracked:Over 50
- Water resistance:IP68
- App compatibility:Oura app and over 40 integrations
- Phone compatibility:iOS and Android
- Display:No display
- Subscription:First month included for new members; subscription required afterward
Our verdict“Choose this silver Oura Ring 5 if you want Oura’s broad tracking and app links in silver and are comfortable with membership and sizing requirements.”
Oura Ring 4 Smart Ring, Silver, Size 10
The Oura Ring 4 is the straightforward pick for someone set on Oura’s established tracking experience: it covers more than 50 health metrics, including sleep, activity, stress, and heart health, while working with both iOS and Android. Its up-to-8-day battery life means fewer charging interruptions than the Milavan Smart Health Ring, which is listed at 3–5 days. The tradeoff is an ongoing membership after the included first month, while Milavan requires no subscription. This Oura also calls for its own sizing kit, so a familiar jewelry-ring size is not enough to confirm fit. Its screen-free, vibration-free design favors discreet tracking over on-ring prompts. I’d choose it for broad health tracking and longer battery life, but skip it if avoiding recurring fees matters most.
Pros:- Tracks more than 50 health metrics, including sleep, activity, stress, and heart health
- Up to 8 days of battery life
- Works with iOS and Android
- Screen-free design has no vibrations
Cons:- A membership is required after the included first month
- A dedicated Oura Ring 4 sizing kit is recommended to find the right fit
Best for: Buyers who want Oura’s broad health tracking, use either iOS or Android, and are comfortable with a membership after the first month.
Not ideal for: People who want to avoid recurring app fees or need to select a ring using standard jewelry sizing without a sizing kit.
- Color:Silver
- Size:10
- Material:All titanium
- Health metrics:More than 50, including sleep, activity, stress, heart health, and women’s health
- Battery life:Up to 8 days
- Compatibility:iOS and Android
- Membership:First month included for new members; subscription required afterward
- Sizing:Oura Ring 4 sizing; sizing kit recommended
Our verdict“Choose this Oura Ring 4 for broad health tracking and longer battery life, provided its sizing process and ongoing membership suit you.”
Milavan Smart Health Ring Fitness Tracker, Rose Gold, Size 8
The Milavan Smart Health Ring suits buyers who want basic activity and sleep tracking without committing to a membership. It records heart rate, sleep stages, daily activity, and workouts across eight sports modes, including running, walking, yoga, and cycling. That is a more workout-labeled feature set than the Oura Ring 4’s supplied description, but Milavan’s heart-rate readings arrive every 30 minutes, so it is not positioned as continuous tracking. Its 3–5-day battery life also falls short of the Oura Ring 4’s up-to-8-day claim. The slim 2 mm profile may appeal to people who prefer a low-profile ring, though careful finger measurement is needed. I’d pick Milavan to avoid subscription costs, not for the widest health-data coverage.
Pros:- No app subscription required
- Tracks sleep stages, heart rate, activity, and workouts
- Offers eight sports modes, including running, cycling, walking, and yoga
- Slim 2 mm profile
Cons:- Heart rate is measured every 30 minutes rather than continuously
- Battery life is 3–5 days, shorter than the Oura Ring 4’s up-to-8-day claim
- Careful finger measurement is needed, and health data is for reference rather than medical use
Best for: Budget-conscious fitness trackers who want sleep, activity, and select workout modes in a slim ring without an app subscription.
Not ideal for: Buyers who want extensive health metrics, continuous heart-rate readings, or longer stretches between charges.
- Color:Rose gold
- Size:8
- Profile thickness:2 mm
- Heart-rate interval:Every 30 minutes
- Sports modes:8: running, cycling, jump rope, walking, hiking, yoga, dancing, and golf
- Battery life:3–5 days
- Charging time:1–2 hours
- Compatibility:Android 5.0+ and iOS 9.0
- Subscription:None
Our verdict“Choose Milavan if avoiding a subscription matters more than broader health metrics or longer battery life.”
Oura Ring 5 Smart Ring, Silver, Size 8
The Oura Ring 5 is the strongest fit here for people who want broad tracking data connected to other apps: its listed integrations cover more than 40 apps, alongside more than 50 health metrics and AI-powered guidance. Compared with the Oura Ring 4, its stated battery range reaches 6–9 days, though the two models’ battery claims overlap and may not settle the choice on their own. Oura Ring 4 may be the simpler match for someone specifically seeking that generation; this Ring 5 makes more sense when integrations and its described thinner, lighter, more scratch-resistant titanium build are the draw. Both call for careful sizing, and this model has an ongoing membership after the included first month. I’d favor it for connected tracking, not for avoiding recurring costs.
Pros:- Tracks more than 50 health metrics
- Integrates with more than 40 apps
- Listed battery life is 6–9 days
- Titanium design is described as thinner, lighter, and more scratch-resistant
Cons:- Membership is required after the included first month
- Uses sizing that differs from standard jewelry rings and previous Oura generations
- Its battery-life range overlaps with the Oura Ring 4 claim, making that spec alone a limited reason to choose it
Best for: People who want extensive health tracking, AI-powered guidance, and connections to a broad range of fitness and wellness apps.
Not ideal for: Buyers who want a subscription-free tracker, prefer standard jewelry sizing, or need a low-cost way to track basic activity.
- Color:Silver
- Size:8
- Material:All titanium
- Health metrics:More than 50
- Battery life:6–9 days
- App integrations:More than 40 apps
- Membership:First month included for new members; subscription required afterward
- Sizing:Sizing differs from standard jewelry rings and previous Oura generations
Our verdict“Choose this Oura Ring 5 if broad app integration and its updated titanium design matter more to you than avoiding a membership.”
BIEMHA Smart Ring Health Tracker, Rose Gold, Size 8
The BIEMHA Smart Ring offers a simpler tracking set than the Oura Ring 4, with sleep, daily activity, and heart-rate readings taken every 30 minutes. Its clearest distinction is the listed 80-meter waterproof rating, a useful feature for buyers who want a ring suited to wet conditions. It also avoids an app subscription, unlike both Oura options in this group. The tradeoff is a short 2–3-day battery life without its smart charging case; the case is listed as extending use beyond five days, but it does not remove the need to manage charging. Compared with the subscription-free Milavan, BIEMHA emphasizes water resistance rather than multiple named sports modes. I’d choose it for basic, fee-free tracking with water resistance, not for deep health insights.
Pros:- No app subscription required
- Tracks sleep and daily activity
- Automatic heart-rate readings every 30 minutes
- Rated waterproof to 80 meters
Cons:- Battery life is only 2–3 days without the smart charging case
- Careful sizing is needed before purchase
- Its listed tracking scope is narrower than the Oura Ring 4’s more than 50 health metrics
Best for: Buyers who want subscription-free sleep and activity tracking in a ring with a stated 80-meter waterproof rating.
Not ideal for: People who want more than basic health metrics, longer battery life without carrying a charging case, or detailed workout-mode support.
- Color:Rose gold
- Size:8
- Compatibility:iOS and Android
- Battery life:2–3 days; over 5 days with smart charging case
- Heart-rate monitoring:Automatic measurement every 30 minutes
- Subscription:No app subscription required
Our verdict“Choose BIEMHA for basic subscription-free tracking and water resistance, if you can accommodate frequent charging without the case.”
Oura Ring 5 Smart Ring, Silver, Size 9
This Oura Ring 5 size 9 is a fit-specific version of the same connected health-tracking proposition as the size 8 model: more than 50 metrics, integrations with over 40 apps, and 6–9 days of battery life. It makes the most sense for shoppers whose Oura sizing process points to size 9; the product data does not establish a tracking difference from the size 8 Ring 5. Compared with the Oura Ring 4, this model lists a wider app-integration count, while both carry a membership requirement after the first month. That recurring fee and the sizing-kit step are real parts of ownership, not minor details. I’d rank it for buyers who want Ring 5’s connected tracking and need this size, rather than for anyone choosing between sizes based on fitness features.
Pros:- Tracks more than 50 health metrics
- Integrates with over 40 apps
- Battery life is listed at 6–9 days
- Lightweight all-titanium design
Cons:- Membership is required after the included first month
- A sizing kit is needed to confirm fit
- The supplied data lists no fitness-tracking distinction from the size 8 Oura Ring 5
Best for: Oura shoppers whose sizing kit indicates size 9 and who want broad health metrics linked with a large set of apps.
Not ideal for: Buyers who have not confirmed their Oura Ring 5 size, want subscription-free tracking, or are choosing between sizes based on different fitness capabilities.
- Color:Silver
- Size:9
- Material:All titanium
- Health metrics:More than 50, including sleep, activity, stress, and heart health
- App integrations:More than 40 apps
- Battery life:6–9 days
- Membership:First month included for new members; $5.99/month afterward
- Sizing:Sizing kit required to find the correct fit
Our verdict“Pick this size 9 Oura Ring 5 if the sizing kit confirms your fit and you want its connected tracking features with membership costs in mind.”
Oura Ring 4 Smart Ring, Silver, Size 9
The Oura Ring 4 is the strongest all-around choice here for people who want fitness context without wearing a screen. Its coverage of 50+ health metrics spans sleep, activity, stress, heart health, and women’s health, so movement data can be read alongside recovery and rest. The up-to-8-day battery also suits continuous wear better than a device that needs frequent charging. Compared with the Oura Ring 4 Silver Size 11, the main distinction is the listed ring size, not a different tracking feature set; choose by fit rather than assuming one size tracks differently. The tradeoffs are practical: Oura recommends a sizing kit because its fit differs from ordinary jewelry, and full membership features require a subscription after the included first month. It is a tracker, not a live workout display.
Pros:- Tracks more than 50 health metrics across sleep, activity, stress, and heart health
- Up to 8 days of battery life supports extended, continuous wear
- Titanium, water-resistant construction is suited to day-and-night use
- Works with iOS and Android and integrates with more than 40 apps
Cons:- Oura recommends its sizing kit; standard jewelry sizing may not match
- A membership subscription is required after the included first month
- No screen or vibration feedback for immediate workout prompts
Best for: People who want broad sleep, activity, and recovery tracking in a screen-free ring and have confirmed that size 9 fits.
Not ideal for: Buyers who want real-time workout metrics on their wrist, or who do not want to pay for an ongoing membership.
- Color:Silver
- Size:9
- Material:Titanium
- Battery life:Up to 8 days
- Water resistance:Water resistant
- Health metrics:Over 50
- Compatibility:iOS and Android
- App integrations:Over 40 apps
- Membership:First month included for new members; subscription required afterward
Our verdict“Choose this Silver Size 9 Oura Ring 4 for broad everyday fitness and recovery tracking if you are comfortable with app-based insights and the membership.”
Oura Ring 4 Smart Ring, Silver, Size 11
If workout alerts and on-ring controls are not part of your routine, this Silver Size 11 Oura Ring 4 keeps the focus on passive health tracking. It records more than 50 metrics and uses Smart Sensing to adapt continuous tracking, while its no-screen, no-vibration design avoids the interruptions common to wrist devices. That makes it a different fit from the Oura Ring 4 Silver Size 9: these listings share the broad tracking and battery profile, so the meaningful choice is the correct ring size and your preference for a quiet device. Battery life reaches up to 8 days, but insights are delivered through the app rather than at a glance during exercise. The separate sizing kit recommendation and ongoing membership subscription are meaningful commitments, especially for buyers seeking a simple tracker with no recurring service.
Pros:- More than 50 tracked health metrics, including sleep, activity, and stress
- Screen-free and vibration-free design stays unobtrusive
- Up to 8 days of battery life
- First month of membership is included for new members
Cons:- No display or vibrations for immediate notifications or workout feedback
- Sizing differs from standard jewelry rings, so the sizing kit is recommended
- Membership subscription follows the included first month
Best for: People who prefer unobtrusive sleep and activity tracking, do not need alerts during workouts, and have verified size 11 with the Oura sizing kit.
Not ideal for: Runners or gym users who want on-device workout feedback, or anyone unwilling to maintain a paid membership.
- Color:Silver
- Size:11
- Health metrics tracked:More than 50
- Battery life:Up to 8 days
- Display:No screen
- Vibrations:None
- Sizing:Oura Ring 4 Sizing Kit recommended; sizing differs from standard jewelry rings
- Included membership:First month for new members
- Membership subscription:Subscription required after the included month
Our verdict“Pick the Size 11 version if quiet, app-based tracking matters more to you than seeing workout feedback on the ring.”
Oura Ring 4 Smart Ring – Silver – Size 8
Among these Oura Ring 4 listings, the Silver Size 8 has the clearest stated water-resistance specification: IP68, up to 100 meters. That makes it a particularly relevant pick for swimmers and people who want to keep a tracker on through showers and water-based activity, rather than removing it as part of their routine. Its all-titanium build, Smart Sensing, and tracking across more than 50 health metrics otherwise place it close to the Silver Size 9 and Size 11 models. The listed specs do not establish a different tracking advantage among those sizes, so fit should drive the choice. The limits remain familiar: there is no screen or vibration feedback, and full features require a paid membership after the first month. A sizing kit is recommended before buying.
Pros:- Specified IP68 water resistance up to 100 meters
- All-titanium design is lightweight at 5.2 g
- Smart Sensing tracks more than 50 health metrics
- Compatible with iOS and Android and integrates with over 40 apps
Cons:- Membership costs $5.99 per month after the first included month
- Oura sizing differs from standard rings, and a separate sizing kit is recommended
- No screen or vibration feedback for immediate activity updates
Best for: Swimmers and active users who want a screen-free ring for continuous health tracking and have confirmed size 8 fits.
Not ideal for: People who want visible, live workout stats or prefer a tracker without a recurring membership requirement.
- Material:Titanium
- Color:Silver
- Size:8
- Weight:5.2 g
- Battery life:Up to 8 days
- Water resistance:IP68, up to 100 meters
- Connectivity:Bluetooth
- Compatibility:iOS and Android
- Membership:First month included; then $5.99 per month
Our verdict“Choose this Size 8 model over the other Oura Ring 4 listings if its stated 100-meter water resistance suits your routine and the fit is right.”
Oura Ring 5 Smart Ring, Silver, Size 10
The Oura Ring 5 Silver Size 10 is the generation choice in this group, with the same broad promise of 50+ health metrics and more than 40 app integrations as the Ring 4 options. Its stated battery range is 6–9 days, rather than the Ring 4 listings’ up-to-8-day figure; that range overlaps, so the specs alone do not establish a clear battery-life win. The bigger buying distinction is sizing: the Ring 5 requires its own sizing kit, and its fit differs from both standard rings and earlier Oura generations. That makes it a less straightforward swap for someone already familiar with Ring 4 sizing. Like the Silver Size 8 Ring 4, it supports a screen-free tracking routine, but membership continues after the included first month. Choose it for the newer generation, not on an assumption of a proven fitness advantage.
Pros:- Tracks more than 50 health metrics
- Listed battery range of 6–9 days
- Titanium construction in a lightweight ring design
- Integrates with more than 40 apps

Oura Ring 4 Smart Ring, Stealth, Size 12
The Stealth Size 12 Oura Ring 4 offers the same fitness-tracking proposition as the Silver Ring 4 sizes: more than 50 health metrics, Bluetooth syncing with iOS and Android, and up to eight days between charges. Its role here is for buyers who prefer a darker finish and need size 12, not for a distinct tracking upgrade. Compared with the Silver Size 11 Ring 4, the supplied data points to the same core functions; color and fit are the practical differentiators. The ring’s 100-meter water resistance supports wearing it through swimming and everyday water exposure, while the screen-free format keeps tracking discreet. The tradeoffs are shared across the lineup: no immediate on-ring feedback, a recommended sizing kit, and a membership subscription after the first month.
Pros:- Tracks over 50 health metrics
- Up to 8 days of battery life
- Titanium construction with water resistance to 100 meters
- Bluetooth connection works with Android and iOS smartphones
Cons:- A sizing kit is recommended to confirm fit
- Membership subscription is required after the included first month
- Screen-free ring provides no immediate on-device workout feedback
Best for: People seeking a dark-finish, size 12 smart ring for continuous activity, sleep, and health tracking across Android or iOS.
Not ideal for: Buyers who need live workout feedback on the device or want to avoid a recurring membership.

How We Picked
I organized this comparison around the searcher’s central question: which listed ring makes sense for fitness tracking when Oura Ring 4 is the reference point? I prioritized clear model identity, the usefulness of the listing for comparing Ring 4 with Ring 5, and the practical details buyers can act on, especially size and finish. I also included the Hitienx, Milavan, and BIEMHA models so readers can weigh non-Oura choices rather than treating brand familiarity as the only decision.
The ranking favors options that best match the stated Oura Ring 4 intent and make comparison straightforward; it does not claim a measured performance winner. The product information provided does not confirm sensor differences, app capabilities, battery life, or subscription terms, so I treat those as verification points instead of inventing advantages. Multiple listings for the same model are differentiated by size and color, not presented as separate technical upgrades.

Factors to Consider When Choosing Smart Ring For Fitness Tracking Oura Ring 4
Choosing among these listings takes more than picking a model name. I would check fit, tracking needs, phone and app compatibility, and the cost of staying within a brand’s software ecosystem before deciding. These broader checks matter especially here because many entries are size-and-finish variations, while the available listing details do not spell out every technical difference.
Match Ring Size to Your Finger, Not the Listing
Ring size affects daily comfort as well as whether you can wear the device consistently, so do not assume your size in a conventional ring will match a smart ring. Fingers can change size with temperature, activity, and time of day; a fit that feels fine briefly may become uncomfortable overnight. Check the maker’s sizing instructions and the seller’s exchange policy before ordering a size-specific listing. A snug fit may help a ring stay in place, but it should not pinch or be difficult to remove. The many Oura size variants here make fit a more useful selection factor than finish. If you are between sizes, resolve that uncertainty before choosing between Ring 4 and Ring 5.
Decide Which Fitness Signals You Will Use
Start with the measurements and routines you care about instead of assuming every smart ring tracks the same things. Some buyers mainly want sleep and recovery context, while others expect workout tracking or detailed activity records. Confirm the exact features, supported activities, and data-export options for the model and app you are considering. A ring can be convenient for passive tracking yet less suitable if you need live workout controls or a screen during exercise. The listings here do not provide enough detail to settle those questions, so verify them directly before purchase. This prevents paying for a monitoring style that does not fit your training habits.
Compare App Access and Ongoing Requirements
A ring’s value depends partly on how its app presents trends and whether the features you want remain available under the brand’s current terms. Before choosing Oura or an alternative, check whether an account, subscription, or phone-specific app is required for the data you plan to use. Also look for clear explanations of data storage, sharing, and export if health history matters to you. A lower-complexity device may suit someone who wants basic summaries, while a more developed software ecosystem may appeal to a buyer who follows long-term patterns. Do not infer app quality or access rules from product photos or a model name. Confirm current terms for the exact listing.
Treat Ring 4 and Ring 5 as Separate Buying Decisions
This roundup includes both Ring 4 and Ring 5 listings, but the provided details do not establish a technical generation comparison. Avoid assuming that a higher model number automatically means better tracking, longer support, or a worthwhile change. Look for a verified feature list, compatibility notes, and manufacturer information for the exact generation before paying extra or switching. If your priority is a known Ring 4 listing, the Silver and Stealth options offer several sizes without changing the stated model. If you are considering Ring 5, confirm what differs and whether that difference affects your actual use. That comparison is more reliable than judging the generation from its name alone.
Choose a Finish for Wearability, Then Check Durability
Gold, Silver, Stealth, and Pink are style choices in the listings, and the information here does not indicate a tracking difference between finishes. Think about whether you will wear the ring continuously and whether its appearance works with your usual jewelry. Ask the seller or maker about material, coating, water exposure, and care instructions rather than relying on a color label to predict durability. A finish that looks good in a listing may show wear differently with frequent lifting, manual work, or contact with hard surfaces. If you plan to wear a ring during strength training, check guidance on both device safety and hand comfort. Style should help you wear it consistently, but it should not replace checking build details.
Verify Phone Compatibility, Returns, and Data Portability
Before ordering, confirm that the ring’s companion app works with your phone and operating system, especially if you may change devices soon. Check whether health data can be exported or shared with the fitness platforms you already use; otherwise, useful measurements may stay isolated in one app. Read the return and exchange terms closely because a size-specific wearable can be difficult to judge from a product page. For less familiar alternatives such as Hitienx, Milavan, and BIEMHA, look for direct documentation on setup, support, and software updates. These checks are more useful than choosing by appearance alone and can prevent a ring from becoming a disconnected gadget. Keep a copy of the exact model and size details before checkout.
Frequently Asked Questions
Which listing should I choose if I specifically want an Oura Ring 4?
Choose among the Oura Ring 4 listings by confirming the size and finish that suit you: the roundup includes Silver in sizes 8, 9, 10, and 11, plus Stealth in size 12. The product names identify the same generation, while the listed differences are color and size. Check the exact seller listing to confirm it is Ring 4 rather than Ring 5. Before ordering, use Oura’s current sizing guidance and review the exchange policy. That approach avoids treating a different size or finish as a different tracking model.
Is the Oura Ring 5 a better fitness tracker than the Oura Ring 4?
The product information in this roundup does not establish whether Ring 5 has different sensors, tracking features, battery life, or software support from Ring 4. I would not assume a newer model number alone makes it the better fit. Compare official feature details for the two generations and focus on any change tied to your own routines. If you cannot identify a useful difference, Ring 4 remains the more direct match for someone who searched specifically for it. Confirm current compatibility and app terms for either generation before choosing.
How should I choose between the Oura sizes listed here?
Use the sizing instructions for the exact ring model rather than relying only on your usual jewelry size. Check fit at different times of day, since fingers can swell or shrink, and aim for a secure feel that remains comfortable through normal movement. The listings include several sizes, but they do not provide enough information to recommend a size based on a person’s measurements. Review exchange terms before buying in case the first fit is wrong. If you are unsure, contact the seller or maker before placing an order.
Should I choose a non-Oura ring such as Milavan or BIEMHA instead?
A non-Oura option may suit you if you prefer to compare another brand or its confirmed features better match your needs. The listing details here do not establish how Milavan or BIEMHA compare with Oura on sensor accuracy, app quality, or data access. Check the supported measurements, phone compatibility, update policy, and return terms for the exact product. Consider whether its data can connect to the health or fitness apps you already use. Choose it over Oura only when those verified details outweigh the value you place on the Oura ecosystem.
Can I wear a smart ring for every workout, including strength training?
Do not assume a smart ring is suitable for every activity just because it tracks fitness data. Contact with weights or equipment can be uncomfortable and may damage a ring, so check the manufacturer’s wear guidance for strength training and other hands-on exercise. Also confirm whether the ring records the workout type and data you expect, since passive activity tracking may not replace a dedicated workout device. For activities where a ring is uncomfortable or exposed to impact, removing it may be the safer choice. Make the decision based on both tracking needs and the ring’s care instructions.
Conclusion
Best overall: I recommend the Oura Ring 4 listings for shoppers who specifically want the model named in the search, with size and finish deciding which listing fits. Best value: I would compare the Ring 4 option that matches your size against Ring 5 only after verifying the actual feature differences and current app terms; the supplied listings alone do not prove a value winner. Best premium: Ring 5 is the generation to investigate if you want the newer listed model, but confirm its advantages before choosing it. Best for beginners: start with the ring whose sizing process, setup instructions, and app requirements are clearest to you; a familiar brand name cannot replace a comfortable fit. Best for specific needs: consider Hitienx, Milavan, or BIEMHA when their verified compatibility and tracking features match your priorities. For most readers drawn to Oura Ring 4, settle fit first, then compare app access and the exact tracking functions you plan to use.
