Circular Ring 3 Hands-On: Tom's Guide Says the New Smart Ring Beats Oura Ring 5 in Three Big Ways

The smart ring category just got another entrant worth watching. According to Tom's Guide, Circular has launched its third-generation ring, the Circular Ring 3, and the outlet's hands-on impressions suggest the new device beats the Oura Ring 5 — along with other leading smart rings on the market — in three major ways.

Tom's Guide, which has covered wearables extensively, framed the piece as a direct hands-on comparison, positioning the Circular Ring 3 as a genuine challenger to Oura's dominance in the smart ring space. The publication did not go into exhaustive technical detail in the portion of the report available here, but the headline claim itself is notable: a smaller, less established brand going head-to-head with the category leader and reportedly coming out ahead on three specific fronts.

Why This Matters for the Smart Ring Market

Oura has effectively defined the smart ring category over the past several years, building a reputation around sleep tracking, readiness scoring, and a subscription-based software layer that keeps users engaged long after the hardware purchase. Any competitor claiming to beat Oura's latest ring — even in a hands-on impression rather than a full long-term review — is worth paying attention to, simply because so few companies have managed to challenge Oura's position credibly.

Circular is a smaller player in this space, and the fact that Tom's Guide chose to frame its coverage explicitly as a head-to-head against the Oura Ring 5 signals that the reviewer saw meaningful, specific differences rather than marginal ones. As Tom's Guide reported, the comparison wasn't limited to Oura alone — the piece states the Circular Ring 3 also outperforms "other top smart rings" in these same three areas, suggesting the advantages are structural to the new hardware or software rather than specific to one rival.

What We Don't Yet Know

It's worth being straightforward about the limits of what's confirmed here. The source material establishes that Tom's Guide conducted a hands-on session with the Circular Ring 3 and identified three specific advantages over the Oura Ring 5, but the detailed breakdown of what those three advantages actually are — whether they relate to comfort, battery life, sensor accuracy, app design, pricing, or something else entirely — sits within the full Tom's Guide article rather than in the summary available for this piece. We'd rather flag that gap than guess at specifics we can't verify.

What we can say, drawing on general, well-established context about how smart rings compete with one another, is that this category typically differentiates itself along a fairly consistent set of axes: overall comfort and sizing options, battery life between charges, the depth and clarity of the accompanying app's sleep and recovery insights, and whether core features sit behind a subscription paywall. Any of these areas — or some combination of them — would be plausible candidates for where a challenger ring might claim an edge, though readers should treat that as general category context rather than a description of this specific report's findings.

The Bigger Picture: A More Competitive Ring Category

The smart ring market has been heating up for a couple of years now, with Samsung, Ultrahuman, RingConn, and others all attempting to carve out space that Oura built almost single-handedly. A hands-on report declaring that a newer entrant beats the current Oura flagship in multiple concrete ways — as Tom's Guide has done here — fits into that broader trend of intensifying competition. It also raises the stakes for Oura, which has generally relied on brand recognition and its research partnerships to maintain its lead even as hardware specs across the category converge.

For consumers already invested in the Oura ecosystem, a single hands-on comparison isn't necessarily a reason to switch — hands-on impressions capture first reactions rather than the kind of extended, real-world testing that reveals how sensors perform across weeks of varied sleep, activity, and skin conditions. But for anyone shopping for their first smart ring, or those on the fence about renewing an Oura membership, this kind of head-to-head coverage is exactly the sort of signal worth factoring into a purchase decision.

What to Watch For

• Whether Tom's Guide follows up with a full long-term review of the Circular Ring 3, which would offer more rigorous testing than a hands-on session.
• How Oura responds, if at all, given that its own Ring 5 is directly named in the comparison.
• Whether other outlets corroborate the specific three advantages Tom's Guide identified, which would lend more weight to the claim.

As with any hands-on report, it's reasonable to treat these early impressions as a first data point rather than a final verdict. Readers who want the full picture — including exactly which three areas the Circular Ring 3 reportedly wins on — should consult the original Tom's Guide article directly, since that is where the granular comparison lives.

We'll continue tracking this story as more detailed, longer-term testing of the Circular Ring 3 emerges, and will update our coverage if Oura or other manufacturers respond to the comparison.
