Finest Costs Right this moment: Round Ring 2
The Round Ring 2 is a brilliant ring that isn’t glad with merely being a substitute for the Oura Ring 4 with out the added subscription. It is a ring that wishes to interrupt new floor when it comes to what a wise ring might be able to.
This the primary sensible ring to incorporate an ECG sensor, with blood stress insights and a glucose tends on the best way too. It is a sensible ring that doesn’t simply wish to make up the numbers.
Round’s earlier efforts have did not impress, nevertheless. However with uncertainty hanging over a few of its rivals resulting from patent disputes with Oura, might Round steal a march and grow to be the sensible ring to get as a substitute of Oura?
I’ve been sporting the Ring 2 for a month now to seek out that out.
Design & Construct
- Obtainable in 4 colors
- IP68 water resistance
- Comes with moveable charging case
The Ring 2 provides you a decide of obsidian black, rose gold, gold or silver colourways. When it comes to sizing, Round covers US sizes from 6-14.
There may be additionally a digital sizing package you need to use to get the most effective match, which ought to be one the place the ring matches comfortable sufficient in order that it doesn’t spin round an excessive amount of in your finger to disrupt monitoring.

I had the Ring 2 in the identical dimension because the Ring, Good Ring Slim and a bunch of different sensible rings I’ve additionally examined, together with the Oura Ring 4 and the Samsung Galaxy Ring. It’s actually a lot nicer-looking than the Round Ring Slim. It’s additionally much less liable to choosing up scratches. Ditching the interchangeable shells from the primary Ring was a superb transfer to make.
It’s a titanium ring, matching the sunshine but sturdy metallic most sensible rings have opted for. There’s a pleasant sheen to the ring’s exterior with a sensor bump that, whereas it doesn’t fully disappear, additionally doesn’t make it uncomfortable to put on.
There’s a small round emblem to remind you of the proper strategy to put on it. I’ve been sporting one on one hand and the Oura Ring 4 on the opposite. The dimensions, thickness and basic presence in your palms is analogous. You do exactly discover the sensor bump much less on the Oura.

Round sticks with a design that has an IP68 ranking for mud and water resistance, in order that’s not the strongest degree of safety towards water for a wise ring, although Round says it’s “secure for swimming, showering, and every day put on.”
It’s good to see that Round has modified its strategy to a charging resolution for its newest ring. It’s ditched the small, keychain-style one it included with its Ring Slim for a charging case.
It has a really completely different look from those included with Samsung and RingConn rings. It’s performed the job of retaining the ring in place throughout charging and gives a built-in battery to allow you to cost on the transfer. Extra on that within the battery life part later.
Well being Options
- ECG measurements
- PPG coronary heart charge and SpO2 monitoring
- Medicine reminders
Once you dive into what’s a reasonably busy Round smartphone companion app (appropriate with each iOS and Android), you’ll recognize simply how a lot is on supply with the Ring 2.
That is nonetheless a wise ring that has the required sensors to trace every day exercise and monitor sleep, together with metrics like coronary heart charge and SpO2. It’s additionally added options to make it a greater match to be used throughout some exercises. It now needs to maintain a better eye on monitoring your emotional state, too.

Let’s begin with the large one each for Round and sensible rings basically. That is the primary sensible ring to incorporate an ECG sensor and options electrodes on the surface of the ring to allow you to take on-the-spot measurements.
These measurements analyse coronary heart charge rhythm and might search for irregular ones. The sensor and algorithm used to do that have each been cleared by the FDA to detect indicators of atrial fibrillation.
Taking a studying is completed by putting the index finger of your reverse hand on the highest of these electrodes. After a 45-second measurement, the studying can be categorised. These will decide that rhythm is regular or present indicators of bradycardia, tachycardia or atrial fibrillation.
Fortunately, all of my readings detected a traditional coronary heart charge rhythm, although curiously acknowledged a confidence between 60-70%. Round, like a variety of tech manufacturers making related wearables, states that this function isn’t a prognosis and doesn’t change a medical system, regardless of sounding very very like a medical function.
Mike Sawh
It can even allow you to generate reviews to point out a medical skilled, so it might at the very least assist together with your well being care. The readings at the very least appeared correct when in comparison with different ECG-reading units just like the Apple Watch.
Past ECG measurements, there’s a complete lot extra on supply right here. You possibly can test reside measurements of your coronary heart charge and SpO2 ranges, arrange alerts for prime and low coronary heart charge or SpO2 ranges (or each) and arrange reminders to take medicine.
I believe the UI within the app must be cleaner and fewer cluttered than it presently is to make absorbing this knowledge loads simpler.
Health & Wellness Monitoring
- Monitor steps, sleep, coronary heart charge and emotional state
- Devoted sports activities modes
- Sleep and Vitality evaluation insights
The Round Ring 2 provides you what have gotten function staples of all sensible rings.
That is one thing you may take to mattress extra comfortably to trace your sleep than a smartwatch. You possibly can put on all of it day and let it preserve tabs in your actions and metrics like coronary heart charge.
It does these issues and extra in an excellent vogue. Nevertheless, for those who don’t sync knowledge regularly, it might probably appear to take an age to sync with the app.
For sleep, you’ll generate sleep scores, get a breakdown of sleep phases and it’ll file sleep length as effectively. It’ll show knowledge like sleep high quality on graphs to see how that modifications or perhaps even stays fixed.
There’s additionally devoted graphs for HRV, respiratory charge, temperature and SpO2 ranges. I’ve been sporting it alongside two completely different sleep trackers. It provided fairly related sleep length knowledge to units like Oura, in addition to recognising sleep begin and wake-up occasions.
Sleep scores had been related, and once I napped, it managed to select them up. At its core, there’s a robust sleep monitoring efficiency.

Each day exercise is damaged all the way down to steps, cardio factors and also will have a look at metrics like VO2 Max and HR max to evaluate Round’s power scores. This rating goals to present you a greater sense of power ranges to deal with your day.
Sleep scores can even affect this rating. Consider it like Oura’s Readiness scores and related metrics on supply on the Google Pixel Watch 4, Samsung’s smartwatches and plenty of Garmin watches. a few of that knowledge in isolation and every day step counts totals had been fairly related on most days in comparison with two different revered and dependable health trackers.
There’s a devoted sports activities monitoring mode, which helps you to decide from a variety of sports activities profiles, together with ones that will profit from piggybacking off your cellphone’s GPS sign to raised observe your actions outdoors.
I’ve used it for out of doors runs and indoor exercises like rowing and biking and the outcomes have been blended. I’ve not examined a wise ring that I actually assume does a superb job of monitoring coronary heart charge throughout train and that hasn’t modified right here.
Mike Sawh
Past exercise, there are options on supply on the wellness entrance which has grow to be extra frequent.
A coherence mode tracks your coronary heart charge variability to assist get you right into a clearer way of thinking. There’s a superb vary of guided respiratory workouts on supply on the app and a spot to control stress ranges and even see predictions on stress primarily based on earlier stress knowledge historical past.
This ring doesn’t shortchange you in options, however isn’t the most effective at presenting them.
Battery Life & Charging
- As much as 7 days battery life
- Moveable charging case
- Totally expenses in half-hour
The Round Ring 2’s strategy to battery, very like earlier Round Rings, is an uncommon one.
You’ve gotten the choice of battery modes – there’s Efficiency mode, which will get you essentially the most correct monitoring on supply and samples knowledge at a better frequency than the Energy battery mode.
The facility saving mode samples coronary heart charge knowledge at a decrease frequency and means you’ll additionally reside with out richer sleep knowledge and fewer detailed knowledge monitoring general.
Mike Sawh
The utmost battery life you’ll get pleasure from is 7 days, which is one much less day than Oura, the identical because the Samsung Galaxy Ring and in need of the comparatively mammoth 10-12 days that the RingConn Gen 2 can preserve going for.
Like earlier Round sensible rings, choosing the efficiency mode does see a way more noticeable drain every day. In that efficiency mode, the battery lasted 4-5 days. That’s higher than earlier than, however not fairly pretty much as good as the most effective sensible ring battery performers.
Moreover, there’s a energy saving mode, which is designed to protect battery once you’re not utilizing the ring for lengthy intervals and isn’t merely draining battery in between the time earlier than you drop it into the charging case once more.
You’ll get a cellphone notification to let you know when it’s working low and now you might have a extra handy strategy to cost it again up. Like Samsung and RingConn, you now have a charging case that may energy the ring again up in simply half-hour.
It’s infinitely extra handy than the keyring USB stick setup of the Round Ring Slim. It’s not fiddly, you may take it wherever and it holds sufficient battery energy to cost the Ring 2 3 times.

The Round Ring 2 launched in August 2025 and is priced at £280/$379 for the most cost effective mannequin. Like earlier Round Rings, there’s no added subscription wanted to achieve full entry to options and knowledge.
Nevertheless, Round can be making some future options accessible by means of a mannequin the place you’ll must amass a certain quantity of its digital Round Cash forex to get them as a substitute. Additionally, you will have the choice to buy these cash to fast-track entry, which can embody an upcoming blood stress traits function.

How does it dimension as much as the competitors? Let’s begin with the best-known, the Oura Ring 4. That ring does depend on a month-to-month or annual subscription, plus wherever from £349/$349 to select up the ring.
The subscription-free Samsung Galaxy Ring sits at £399/$399, so each Samsung and Oura rings are costlier as compared, although Samsung doesn’t require a subscription.
The Ultrahuman Ring Air prices £329/$349 whereas the RingConn Gen 2 sits at $299. These two rings on the time of writing had been set to be pulled from sale within the US after Oura gained a patent infringement submitting towards the 2 new sensible ring newcomers. That might, after all, change sooner or later.
That would depart Oura, Samsung, Amazfit and Round as the primary gamers within the sensible ring area. Samsung, although, has seen latest issues with battery swelling on the Galaxy Ring.
Do you have to purchase the Round Ring 2?
I examined the unique Round sensible ring and I didn’t even full my testing resulting from so many points. I had extra luck with the Round Ring Slim, however it nonetheless couldn’t compete with different sensible rings.
With the potential that Ultrahuman and RingConn rings could possibly be banned from the US, that leaves a a lot smaller competitors for the Round Ring 2. You’ve primarily acquired the Oura Ring 4, Samsung Galaxy Ring and the Amazfit Helio Ring.
I might nonetheless say the Oura Ring 4 is the standout sensible ring after my time with the Round Ring 2. It’s actually the most effective Round ring I’ve examined and whereas Samsung’s software program feels somewhat cleaner as compared, Round’s software program is clearly constructed for a wise ring and will meet up with a while.
When you’re in search of a subscription-free sensible ring, then that is actually up there as a prime choice.
