Leep Ring 1 for $200: An innovative UK-made intelligent ring, budget-friendly, requiring no subscription, and delivering straightforward, understandable metrics on your movements, slumber, and tension? Count me interested. Its design is slender and elegant, featuring a delicate diagonal groove designed to aid in aligning the tactile internal sensors. A convenient charging container accompanies it, purportedly capable of supplying an additional two months of power. When fully powered, the ring is intended to function for as long as eight days. (My personal experience has shown closer to five.) The application is user-friendly (currently exclusive to iPhones, with an Android version under development) and assigns a comprehensive score, out of a possible 100, for rest, equilibrium (stress levels), and physical exertion. Regrettably, its sleep tracking is highly imprecise, frequently indicating I was asleep for the duration of my time in bed, even when engaged in television viewing or reading. On the previous evening, it indicated I had 8 hours and 43 minutes of sleep (whereas Oura reported 6 hours and 52 minutes). The metrics for activity and stress appear somewhat more precise, with step tallies largely within approximately 100 steps of my Oura and Apple Watch readings (though it deviated by 1,000 on one occasion). However, the application could benefit from refinement. As an illustration, it fails to consider that only a few hours have passed in the day before declaring my current movement “Poor.” Furthermore, I experienced data loss on the initial night its power depleted, and no alert was issued to prompt me to recharge it. Leep is in its nascent stages and is quite affordably priced, yet rapid enhancements are necessary for it to remain competitive.

Luna Ring 2.0 for $329: Challenges with power replenishment and network linking plagued the inaugural Luna Ring, but the Indian producer appears to have implemented substantial enhancements in its second iteration. My Luna Ring 2.0 was accompanied by an elegant wireless power-up enclosure (which costs $29 less with the standard charging base) purporting to deliver up to a month of energy. While the ring is intended to operate for five days between charges, my experience suggests four days is a more realistic duration. The diagonal indentation on the ring’s face is not to my liking, and its comfort level falls short of my Oura. It features the customary array of sensors for monitoring (including optical heart rate, blood oxygen saturation, photoplethysmography, and dermal temperature). Information is categorized into sections for rest, preparedness, and physical effort within the feature-rich application, complete with the expected artificial intelligence functionality for guidance and perspectives. A significant advantage is the absence of a required subscription, and while the data appeared reasonably precise, it certainly erred on the side of liberality. When juxtaposing a complete day with my Oura, the Luna indicated an additional hour of slumber, a 100 kcal higher caloric expenditure, and assessed my readiness as exceeding 80 out of 100, whereas Oura registered a considerably lower score and detected an underlying strain on my system (I am presently experiencing a common cold). Should a subscription-exempt ring be your preference, I favor the Ultrahuman model previously mentioned.

Circular Ring 2 for $349: Possessing rounded edges, this ring presents an attractive appearance, resembling an item of jewelry more closely than the Oura or Ultrahuman rings. The enclosed charging container is also appealing, enabling portability for travel and recharging without needing a USB-C cord; furthermore, I appreciate the ring’s intermittent alerts during the day, signifying optimal periods for efficiency, exercise, or caffeine intake. Nevertheless, throughout my fortnight-long evaluation phase, I was troubled by unceasing server malfunctions and holdups in data processing, which hindered my ability to verify the precision of any health measurements, such as pulse rate, oxygen saturation, or sleep information. Consequently, endorsing this ring at present becomes challenging. I intend to retain it for the time being to observe if these issues ameliorate.—Adrienne So
Movano Evie Ring for $269: Upon its initial release, the Movano Evie Ring was promoted as the globe’s premier fitness monitoring device engineered exclusively for females. My anticipation was considerable! Recent updates have allowed it to integrate with Apple Health (within the iOS application), now permitting users to view their cycle day on the main screen, manually record basal body temperature, and manually input exercise sessions. Nonetheless, these recently introduced functionalities appear rather underdeveloped when juxtaposed with those provided by rival products. With Oura and the Galaxy Ring now capable of precisely monitoring menstrual cycles, this ring’s relevance might be diminishing. Yet, its comparatively low cost, absence of a recurring fee, and inclusion of a blood oxygen detector are somewhat advantageous. —Adrienne So
RingConn Gen 2 for $299: Even with an elevated price point compared to the first generation mentioned below, this intelligent ring remains comparatively economical and free from recurring subscription charges. RingConn maintained its unique angular aesthetic; however, this second-generation iteration introduced significant enhancements to slumber monitoring (such as detecting sleep apnea), extended battery endurance, and boasts a marginally more slender and lighter profile. I observed that fundamental sleep and wellness tracking was robust (with sleep precision notably superior to the initial generation), yet exercise monitoring continues to be a considerable shortcoming. Even with an expanded selection of workout categories, users are required to manually initiate exercise tracking, and the device exhibits difficulties in maintaining accuracy during periods of elevated heart rate.
RingConn Smart Ring for $99: Currently offered at a substantial reduction, the inaugural Ringconn warrants consideration. Its subtly angular form, complete with chamfered edges, bestows upon it a distinct aesthetic; health and sleep monitoring function effectively, and it sustains operation for four or five days between power replenishments. Additionally, it includes a practical battery enclosure (sufficient for multiple recharges while mobile). Nonetheless, I encountered difficulties with data synchronization, the application offered inadequate exercise tracking, and the information was occasionally imprecise, although the app is progressively enhancing through subsequent revisions.
Amazfit Helio Ring for $200: As a provider of economical fitness monitors such as the Amazfit Active 2, my anticipation was for a formidable intelligent ring from
Amazfit, but the Amazfit Helio itself is notably subpar. I appreciate its delicately patterned bronze finish, yet this is the sole hue offered. Furthermore, dimensions are presently restricted to 8, 10, or 12 (with sizes 7 through 13 anticipated soon). Though possessing comparable functionalities to the aforementioned smart rings, the Helio frequently proved utterly imprecise; heart rate measurements, for instance, were considerably inconsistent when compared to other monitoring devices. It is missing automated exercise monitoring, its battery typically lasted three days for me, and the Helio often lost connection from the overloaded and perplexing Zepp application. While a membership isn’t strictly required, Aura AI ($70 annually) is available for sleep analysis and content, or Fitness ($30 annually) which features an AI coach. These options are both costly and perplexing. (The rationale behind two distinct subscriptions is unclear.) The Helio functions far more effectively in combination with a smartwatch (I tested it alongside the Amazfit Cheetah Pro), allowing it to amalgamate the information. However, as an independent gadget, it is unfeasible to endorse.
How Do I Select the Appropriate Smart Ring Size?
While some smart rings are offered in conventional sizes, there’s a discrepancy, and half sizes are uncommon. Therefore, it’s prudent to invest time verifying you acquire the appropriate ring size. Most producers will furnish you with a complimentary sizing kit, allowing you to wear a mock ring for a full day. (You might need to purchase the ring straight from the manufacturer to receive this kit without charge.) You should definitely undertake this. Remember that your fingers expand and contract over the course of the day. Your smart ring needs to be closely fitted to permit the sensors to obtain precise readings. However, you will need to periodically remove it to recharge, so an excessively constricting fit is undesirable.
On Which Digit Should I Place My Smart Ring?
You may place your smart ring on any digit, yet most manufacturers suggest wearing these devices on your pointer finger, although the middle or ring finger can also function. These three digits all possess ample blood vessels, facilitating greater precision in heartbeat tracking. What’s truly crucial is that the ring fits snugly and firmly around the base of your selected digit. Thus, if you possess a prominent joint and a slimmer finger base (a more frequent occurrence with the middle or ring finger), this might prove challenging. I advise placing it on the pointer finger of your non-dominant hand. I observed that wearing it on my right index finger, as a right-handed individual, resulted in increased harm to the ring and abrasions on various objects I handled.
Which Smart Ring Finish or Hue Is Optimal?
All the smart rings we examined featured robust titanium integrated with an internal sensor cluster, however, the external finishes and hues differ. If you are prone to harshness with rings, a silver or gold surface will probably be ideal, as it presents a reduced likelihood of harm. My Oura and Ultrahuman rings, featuring dark finishes, showed noticeable scratches and nicks after some time. Our Galaxy Ring evaluation model has been worn by an assessor for over twelve months, and the perimeters of the titanium black ring currently appear silver.
The Oura, Samsung, and Amazfit rings possess miniscule indentations designed to assist in positioning the sensors. Although I prefer the Ultrahuman’s sleek surface, I believe proper positioning significantly enhances precision.
How Do I Maintain My Smart Ring?
Most smart rings are resilient, however, to prevent harm, you should take off your ring when handling instruments, lifting weights, scrubbing cookware, or even polishing the basin. Should your ring be prone to friction with a surface, remove it. I observed this presented a greater issue when wearing a ring on my pointer finger, compared to the middle or ring finger. I marred the Oura and Ultrahuman rings during gardening activities, relocating containers, and employing a hand weight. Titanium is also sufficiently robust to blemish household areas. I scored the ceramic of my sink and stained the interior of a cup with the sharp-edged Ringconn. All the smart rings we examined are impervious to water, thus you can swim or bathe without removing them.
How Frequently Do I Require Recharging My Smart Ring?

Intelligent bands are supplied with a charging unit and cord, though you’ll typically need to furnish your own wall adapter. From completely depleted, they necessitate anywhere from ninety minutes to three hours for a full charge, but you should endeavor to prevent the battery from draining entirely, lest you risk losing crucial health metrics. Our assessment of the intelligent bands mentioned above involved activating all supplementary features, consequently, our projected battery durations are less than the figures advertised by the producer.
Which Characteristics of Intelligent Bands Ought I Seek?
The majority of intelligent bands monitor your slumber, pulse rate, and bodily warmth. Should you wish to vigilantly observe your sleep patterns and acquire health data discreetly and without discomfort, intelligent bands serve as a perfect solution. Physical activity monitoring differs; most intelligent rings provide fundamental step tallies and motion detection, some facilitate manual exercise logging, while others feature automated workout identification. Nevertheless, greater detail and precision can be anticipated from a conventional activity monitor or intelligent timepiece. Integrating an intelligent ring with an Apple Watch or Fitbit yields a fluid interaction, enabling you to remove the watch and permit it to recharge overnight, thereby avoiding interruptions in your data collection.
Intelligent Bands or Smart Timepieces?
Over recent years, numerous inquiries have reached us concerning the rationale behind acquiring an intelligent ring in lieu of, or supplementary to, a standard activity monitor or intelligent timepiece. Several considerations that might sway your decision are presented below:
Enhanced power duration. An intelligent band is more compact and typically (if not invariably) boasts superior battery endurance. It serves as a beneficial inclusion to your collection if you dislike forfeiting a few hundred, or even a thousand, steps daily during your smartwatch’s recharge.
Slumber monitoring. It’s not by chance that our preferred sleep monitor is a compact, subtle band. Perhaps you’re weary of your bulky Apple Watch Ultra striking your visage each time you shift position. (Or perhaps you’re replenishing its power at that moment!)
Menstrual rhythm observation. Numerous timepieces and activity monitors now incorporate a dermal temperature sensor sufficiently sensitive to identify illness or alcohol consumption. Nonetheless, based on Adrienne’s evaluations to date, merely the Samsung Galaxy Ring and the Oura have demonstrated adequate precision for monitoring her menstrual cycle.
Ultimately, style. Timepieces signify a declaration and an emblem of standing; an intelligent watch frequently conveys no more regarding your inclinations and selections than “I prefer not to miss appointments.” Nearly everyone we are acquainted with who has obtained an intelligent band did so because they possess a bequeathed Cartier Tank, or an enjoyable Casio or Swatch, which they are reluctant to relinquish. If this describes you, splendid! And procure a band!
Our team has consistently adorned intelligent bands for a span of several years (occasionally donning two or three concurrently), thereby gaining substantial expertise on what renders an intelligent ring a worthwhile acquisition. Each intelligent band undergoes testing by being worn for a minimum of one month, often exceeding this duration, and its monitoring information is invariably benchmarked against our premier selection (Oura) as well as other intelligent timepieces and activity monitors (Apple Watch).
We are presently re-evaluating the Circular Ring 2 and the forthcoming RingConn Gen 3.
