The short answer: if you want a smart ring, Oura is the one the research covers best, and it costs about $615 over three years for a Ring 5 at the $399 US list price plus Oura’s $5.99 a month membership (arithmetic: $399 plus 36 months at $5.99). Studies agree on what rings do well, sleep versus wake and overnight heart rate and HRV, and where they fall short, individual sleep stages and single nights. None shows that wearing a ring improves health. This is general information, not medical advice.
What the current Oura rings cost
Prices were read on Oura’s own US store pages on 2 Oct 2026. Only the Black and Gold Ring 5 and the Silver and Gold Ring 4 were read; other finishes may differ, and Oura changes prices and promotions, so check before buying.
Three-year cost (arithmetic from the list prices above)
New members get the first month free, per Oura, which takes $5.99 off. The $69.99 annual option, which Oura lists for US members, would make three years $209.97. If you stop paying, Oura says the ring and app still work, your data stays in your account, and you can export it as CSV, but insights are “much more limited”.
Other smart rings
- Samsung Galaxy Ring: Samsung’s US page lists it from $299.99 before trade-in credit and mentions no subscription fee; it needs a compatible Samsung Galaxy phone for full functionality, per the same page. We did not read a regular list price.
- Ultrahuman: its US page lists the Ring PRO at $479 as a pre-order shipping 10 October. Its global Ring AIR page lists $349 and states no recurring subscription fees for accessing data, but we could not confirm that price applies to US buyers.
- RingConn: its pages returned errors when we read them, so we give no price or subscription terms; check ringconn.com.
- Patents: Oura won a US trade commission ruling against Ultrahuman, with an exclusion order reported as taking effect in October 2025 (Bloomberg Law, Inc42). The press also reports that Oura licensed its patents to RingConn in a settlement, and that Ultrahuman returned to US pre-orders in March 2026 with a redesigned ring that Customs ruled outside the order. We rely on press for this; check before buying from a non-Oura brand.
- Validation: our PubMed searches on 2 Oct 2026 for Galaxy Ring, RingConn and Ultrahuman validation studies against polysomnography or ECG found no study of those rings. That is not proof they are worse, only that independent evidence is missing.
Validation studies, graded
Grade = how far the design supports the claim. All are device-versus-reference studies; none shows a health benefit.
Reading across: the evidence is good for sleep versus wake and for overnight heart rate and RMSSD, mixed for sleep stages (50 to 80% depending on method), and absent for readiness scores or temperature features. Accuracy for older adults and patients looks worse. Most studies name Gen 2, Gen 3 or Gen 4, so applying them to Ring 4 or 5 is an assumption. See the cross-device summary in what the validation studies show across wearables.
Who it suits
Pick a smart ring if you want screenless overnight heart rate, HRV and sleep timing, and accept that stage percentages are rough. Compare the trade-offs with a band in WHOOP vs Oura, with a watch in Apple Watch health features, or against other wearables in best wearables for longevity. For the number most rings headline, see the HRV guide. Skip it if you want GPS or a screen, or reliable stage-by-stage data. Persistent sleep problems need a clinician, not a score; see best sleep tools.
Method note
Researched from Oura’s membership, store and support pages, press reports, other makers’ US pages where readable, and PubMed abstract records, checked 2 Oct 2026. We did not test any ring.
