Most individuals would not purchase a wise ring for health monitoring, and for good purpose. They’re unbelievable, seamless choices for passive well being information, and surprisingly respectable at step counts in the event you ignore the false positives from gestures. However for health monitoring, just about each model we have examined has given less-than-accurate outcomes, to place it mildly.
So when Oura offered its new Oura Ring 4 as a greater health possibility, with its Computerized Exercise Detection and improved real-time HR information throughout exercises, I bullied our Oura reviewer into going for a run and understanding to check this declare for himself.
Our managing editor Derrek Lee is constructing an actual assortment of good rings now, with the Oura Ring 4, Amazfit Helio Ring, and RingConn Gen 2. I requested him to work out whereas carrying every, in contrast in opposition to smartwatches that we have examined with dependable optical coronary heart charge accuracy, and see how shut the good rings got here to a correct end result.
I additionally slipped on my Ultrahuman Ring Air to see the way it carried out, whereas together with the health check we carried out throughout our Samsung Galaxy Ring overview. This is what we realized!
Why testing good ring accuracy is so laborious
Earlier than I present the outcomes, I am going to level out that this check will not be as detailed and graph-happy as my earlier health exams, like my low cost health watch accuracy check or my Garmin v. Coros v. Polar flagship showdown.
Why? Most good ring apps (moreover Amazfit’s Zepp Well being) haven’t got the instruments to export coronary heart charge graphs for particular exercises, like you’ll be able to with established health watch manufacturers. We tried to export Oura’s GPX recordsdata from Derrek’s Strava account and it made my ordinary HR graph device crash each time I attempted to add it.
Plus, a few of these good rings do not even allow you to set off a guide exercise until it is a particular kind, like strolling or operating. For some manufacturers like RingConn, we needed to trick the app by saying Derrek was “operating” throughout a fitness center exercise to have it save his coronary heart charge information. With no exercise mode, good rings do not pattern your coronary heart charge often sufficient for the outcomes to be in any respect useful.
Level being, I am principally making these comparisons primarily based on coronary heart charge averages and eyeballing HR graphs from slapdash guide exercises. However don’t fret: It is nonetheless sufficient information to point out how middling most of those good rings are for health.
Testing good ring coronary heart charge accuracy throughout exercises
For this good ring health accuracy check, Derrek ran as soon as and accomplished 4 fitness center exercises, carrying two watches — the Garmin Venu 3 and Pixel Watch 3 — and three good rings from Amazfit, Oura, and RingConn. These had been the outcomes:
| Machine title | Exercise 1 (HR common / max) | Exercise 2 | Exercise 3 | Exercise 4 | Exercise 5 |
|---|---|---|---|---|---|
| Garmin Venu 3 | 152 bpm / 179 max | 100 bpm / 137 max | 123 bpm / 158 max | 98 bpm / 127 max | 151 bpm / 186 max |
| Google Pixel Watch 3 | 148 bpm / 178 max | 103 bpm / 150 max | 123 bpm / 160 max | 104 bpm / 140 max | 148 bpm / 172 max |
| Amazfit Helio Ring | 148 bpm / 175 max | 103 bpm / 145 max | 123 bpm / 153 max | 103 bpm / 128 max | 150 bpm / 176 max |
| Oura Ring 4 | 139 bpm / 153 max | 109 bpm / 143 max | 116 bpm / 145 max | 102 bpm / 116 max | 95 bpm / 109 max |
| RingConn Gen 2 | 134 bpm / 164 max | 83 bpm / 101 max | 88 bpm / 117 max | 84 bpm / 97 max | 88 bpm / 102 max |
With no correct chest or arm strap, I can not say for sure whether or not the Venu 3 or Pixel Watch 3 was extra correct for Derrek; the Venu 3 did very effectively in my overview in comparison with a COROS band, whereas I gave the Pixel Watch 3 a “B” for accuracy in its overview, usually extraordinarily correct however struggling within the 160+ bpm vary. Nonetheless, you’ll be able to see that each match one another pretty intently, as a benchmark for what wrist-based optical sensors sometimes provide for accuracy.
Now evaluate these three good rings’ huge hole in outcomes. You may see that solely the Amazfit Helio Ring is constantly correct — particularly if we flip a coin and assume Google is extra correct than Garmin right here. Its averages are very a lot on level, and whereas its max-HR information falls brief, it isn’t as underestimated as Oura or RingConn.
It is not excellent, after all. You’ll be able to see within the two coronary heart charge graphs under that it falls effectively wanting Garmin for an prolonged stretch as soon as Derrek’s coronary heart charge reaches sure heights; within the second graph, it is at all times shut however tends to point out small valleys the place Garmin peaks. However general, it is nearer than I anticipated from any good ring.

Oura would not do badly for low-aerobic exercises within the 100–130 vary, however the larger Derrek’s coronary heart charge climbed, the extra difficulties the Oura Ring 4 had. Within the final exercise, the center charge chart confirmed an enormous 60–70 bpm hole for a lot of the exercise.
Picture 1 of 2
RingConn’s stats are to date off that Derrek speculated that the difficulty is likely to be that he was pressured to put on it on his ring finger as an alternative of his ordinary index finger (he solely has so many fingers, in spite of everything), leaving it too free for a correct studying. Which may clarify the difficulty, so we can provide RingConn a tentative cross right here, whereas nonetheless conserving the info for now.

I’ll level out that in the event you put on a smartwatch too loosely or too tightly, your outcomes will probably be skewed, too…however not this a lot. It goes to point out how necessary a wise ring’s match is for correct outcomes.
Nick and I personal the Galaxy Ring and Ultrahuman Ring Air, respectively, with no different good rings. So our exams are extra simple, exhibiting how they evaluate in opposition to our smartwatches of selection.
Picture 1 of 4
Nick already wrote in regards to the Galaxy Ring’s health struggles in his overview: The Pixel Watch 2 and OnePlus Watch 2 averaged 170 and 169 bpm throughout a tough Spartan Race; the Galaxy Ring averaged underneath 150 bpm, randomly splitting the race throughout two actions.
As for my Ultrahuman Ring Air, it nonetheless lists its Exercise Mode as in Beta about half a 12 months after I completed my overview, and the outcomes are nonetheless wonky. In contrast to different good rings that severely underestimate your energetic coronary heart charge, Ultrahuman instructed me my coronary heart charge common was 182 bpm for a observe exercise when Garmin stated it was 168 bpm. A few days later, it instructed me my common throughout a lightweight run was 153 bpm; Garmin registered 143 bpm and stated 153 bpm was my max.
Does good ring health accuracy matter?
As I stated from the start, most athletes will not purchase a wise ring particularly for exercises. Runners and cyclists need a look ahead to its GPS and display screen information, and whilst you can raise weights whereas carrying a wise ring, it could possibly distract out of your grip and get scratched up until you connect a silicone cowl.
Nonetheless, even when individuals do not count on a wise ring to be excellent, they need ballpark accuracy to allow them to maintain observe of burned energy. And since manufacturers like Oura and Ultrahuman attempt to estimate your VO2 Max or Cardio Capability, it is necessary that they achieve this with correct information as an alternative of inadvertently deceptive individuals.
I got here into this check assuming that the brand new Oura Ring would sweep away the competitors, however you already know what they are saying about assuming! As a substitute, it is the Amazfit Helio Ring that received the {hardware} accuracy contest. And since Amazfit lately discounted it to $199 and made its expensive subscriptions free, the Helio Ring has change into extra interesting.
Then again, the Helio Ring has unresolved issues just like the restricted variety of sizes (three), brief battery life (4 days), and lack of automated exercise detection. You may nonetheless want an Oura Ring with its middling accuracy as a result of you do not have to manually begin a exercise within the app each time you run or raise weights.
In different phrases, the entire greatest good rings have work to do on the health entrance, however possibly they’re shut sufficient for on a regular basis athletes to not thoughts the accuracy gaps. Both that or they’re going to simply maintain utilizing their health watches as an alternative and solely use good rings for well being and sleep information.
