Good rings might be extra comfy and unobtrusive to put on than the greatest health trackersand after I examined the Oura Ring I used to be impressed by the upper stage of accuracy it supplied for sleep monitoring when in comparison with sports activities watches.
I hoped that the Round Good Ring Slim may be equally efficient and turn out to be a rival to the Oura however, after a month of testing, the Round Slim has did not wow me, with the design and the accuracy of its monitoring falling quick.
Round Good Ring Slim: Worth And Availability
The Round Ring Slim launched in November 2023 and prices £225 within the UK and €259 in Europe. That is cheaper than the Round Professional 1 (€364), which is bigger and is available in one among 4 finishes versus the Slim’s one. The ring ships worldwide, so might be bought within the US.

On the time of writing the Round Ring Slim was out of inventorybut it surely’s doable to enroll in notifications as to when it’s subsequent accessible.
How I Examined This Good Ring
I’ve worn the Round Ring Slim day and evening for a month, solely taking it off to cost it—although this was very often. Throughout testing I additionally wore the Oura Ring 3 to check the readings, in addition to the Garmin Epix Professional and Apple Watch Extremely 2. Except for the previous two variations of the Oura Ring, that is the one sensible ring I’ve examined.
Design
The Slim within the ring’s title is justified. The place the Oura Ring is 2.55mm thick, the Slim is simply 2.2mm; it’s additionally mild, at 2g, and comfy to put on day and evening. It’s 8.8mm vast and has a small white brand on the highest that exhibits which approach up it’s meant to be worn. To me, this isn’t an interesting or delicate design function, although the larger design concern is the supplies used. The Round Slim is created from a mixture of aluminum and carbon fiber, relatively than a hardier materials, like titanium, and the result’s that it scratches simply and has a plastic really feel when put next with the titanium Oura Ring.
The ring turned scuffed inside days of beginning to put on it, with silver scratches displaying via the black exterior and decreasing the enchantment of its design additional. The ring isn’t waterproof, simply waterproof sufficient to resist splashing when washing your arms or showering. For now, it’s additionally solely accessible in a single coloration: matte black.
As with different sensible rings, you’re despatched a sizing package while you order to make sure you get the precise match. The ring must be tight so the sensors take an correct studying and it’s smart to put on the sizing package rings 24/7 to see how they really feel when your fingers swell. The Slim is filled with sensors to trace your sleep and each day exercise. It has infrared, purple and inexperienced LED sensors, a floor temperature sensor and a three-axis accelerometer. There’s a haptic button the place the emblem exhibits on the highest of the ring that you should use to show off options just like the vibrating alarm powered by the motor within the ring.
Within the field is a charger that plugs right into a USB-C port on which the ring sits. The charger is neat and has a keyring on it, however the best way the ring has to sit down on it means it’s laborious to make use of the charger when plugging it into a pc on a desk.
Sleep And Exercise Monitoring
The Round Slim tracks plenty of information about you. On-board sensors monitoring coronary heart charge, coronary heart charge variability (HRV), sleep levels, blood oxygen saturation, stress ranges and much more. There’s a 14-day calibration interval to set your baselines, so it’s solely after two weeks that you simply begin getting helpful insights into the state of your physique.
The headline stats are delivered within the app via “Circles”, which give sleep rating, power rating (much like the readiness rating you get on different gadgets) and stress ranges. You too can take a reside measurement with the ring to indicate your coronary heart charge, HRV and blood oxygen saturation.
You’ll be able to then click on on the Circles for detailed details about sleep and power ranges. As with different sensible rings, I discovered sleep evaluation essentially the most fascinating side of the monitoring, with data on how lengthy it took me to fall asleep, my general sleep debt, and the way stressed I used to be in a single day, alongside extra widespread options like sleep levels. The Slim additionally tracks HRV and temperature and plots them in opposition to your baseline.
In the course of the day the ring tracks steps, energy burned and coronary heart charge, awarding “cardio points” for while you’re lively in addition to monitoring stress ranges. I discovered the step monitoring usually confirmed totals decrease than the watches I wore that day, however not by a lot. The ring can’t monitor exercises, nor can it pull exercise information from Apple Well being or Google Match to fill on this information within the app, in contrast to the Oura Ring.
Sadly, the accuracy issues I noticed with the ring’s in a single day monitoring had been in depth. My temperature fluctuated a weird quantity all through testing, together with one evening the place it was proven as 7.3°C (roughly 12°F) under regular, whereas different trackers and the Oura ring confirmed regular readings.
I’ve barely had a minute of deep sleep all through the month, in keeping with the ring, once more when different trackers have noticed I often get 40-50 minutes an evening. My sleep scores have typically did not tally up with actuality too: I used to be getting 90+ scores for per week regardless of being commonly woken by a child and staying up late and consuming alcohol one evening. My resting coronary heart charge information can also be increased than with different gadgets, and a few nights I get no sleep information in any respect from the Slim, or no sleep levels.
Some information has been correct, or at the least in step with different gadgets, such because the instances I fell asleep and awoke, although the Round Slim missed instances I woke within the evening often, and the HRV measurements have been much like these of the Oura Ring and Garmin watch.
The App
The Round app is busy-looking, which isn’t shocking given the quantity of knowledge the ring collects, but it surely’s a bit cluttered and when you look past the Circles on the high of the app the info is overwhelming. The Oura app is cleaner and extra gratifying to make use of, although at the least the Round app doesn’t require a subscription to make use of it.
It takes time to sync the ring with the app although, and typically I couldn’t discover the time to attend for the info to indicate up within the morning. The ring shops 20 days of knowledge so you are able to do a catch-up sync at one other level, however this sluggish sync is once more worse than the expertise with the Oura Ring, which flashes up sleep and readiness scores shortly after you open the app within the morning.
There have been additionally bugs with the Round app, similar to frequent notifications that I used to be offline (after I wasn’t), and that I couldn’t rename the ring (after it informed me I may rename the ring after I first set it up).
One novel function with the Round Slim is the AI assistant Kira+, which provides each day suggestions based mostly on the info tracked by the ring. Sadly, this wasn’t as sensible as I’d initially hoped. Kira+’s solutions had been an extended stream of textual content telling me, as soon as extra, the info the ring has tracked, plus primary recommendation like doing respiratory workouts and conserving your bed room cool and comfy at evening.
You’ll be able to set an alarm clock within the app, together with a wise alarm function that wakes you in a window of time based mostly in your sleep patterns. The ring vibrates to do that, and also you flip off the vibration by tapping the emblem. It’s an unobtrusive technique to get up when others are in mattress with you.
Battery Life
The Slim is listed as lasting as much as 5 days on a cost, however that is in Eco mode, which reduces how typically it takes coronary heart charge readings and doesn’t monitor your sleep levels. In Efficiency mode the ring lasted two days (at most), which is lower than the 4 days I usually get from the Oura ring.
Is The Round Good Ring Slim Price It?
I’d avoid the Round Slim. To me, the design isn’t significantly good and it scratches simply, and I’ve reservations in regards to the accuracy of its monitoring. The battery life is brief and the Oura Ring is solely a greater all-round product. I’ve not but examined different rings just like the Ultrahuman Ring or RingConn Good Ring, which can be higher alternate options to Oura than the Round Slim.
