Smart ring true cost: what Oura, RingConn and WHOOP add up to over three years
Updated Aug 27, 2026 ยท prices dated per offer
The advertised price of a smart ring tells you almost nothing about what it will cost you. Two of the devices below charge you again every year to keep working, and one of them does not sell hardware at all. So we did the only comparison that means anything: add the device price to the published subscription price times 36 months, and see where everyone lands.
RingConn Gen 3 was $349 on RingConn's site when we checked on August 17, 2026, and RingConn states no subscription is required. Three-year total: $349.
Oura Ring 5 was $399 at Target on August 17, 2026 for the Silver and Black finishes, with other finishes at $499 per Oura. The membership is $69.99 a year or $5.99 a month per Oura, and only the first month is free with a new Ring 5. Three-year total on the annual plan: $399 plus $209.97, which is $608.97. On the monthly plan it is $399 plus $215.64, which is $614.64. Choose a $499 finish and you are at $708.97.
WHOOP is not sold as hardware. Per WHOOP there are three annual membership tiers, One at $199, Peak at $239 and Life at $359, and the band is included with each. Three-year totals: $597, $717 and $1,077. WHOOP's listed price of $199 is therefore not a device price at all, it is one year of a bill that repeats.
The ranking that falls out is not the ranking the sticker prices suggest. RingConn is $349. WHOOP One is $597. Oura is $608.97. WHOOP Peak is $717. WHOOP Life is $1,077. The device that looks $50 cheaper than the Oura on day one ends up costing $260 more over three years. Everything here estimates sleep stages from movement and heart signals rather than measuring brain activity, and none of these consumer models is FDA-cleared to diagnose anything.

Lowest three-year cost: $349
1. RingConn Gen 3
One payment, no renewal. RingConn states that all app features, including sleep staging, HRV, SpO2, skin temperature and vascular health trends, are included with the ring, so the $349 we read on RingConn's site on August 17, 2026 is the whole bill for as long as you wear it. Battery is quoted at up to 14 days, and the ring is rated to 10 ATM with a free sizing kit shipped before the real one.
Where the money shows up missing is the software. Reviewers describe the app as less polished than Oura's, heart rate during hard exercise is reported as inconsistent, and some Gen 3 features were still rolling out at launch. You are trading interface quality for $259.97 against the Oura over three years.
Skip it if: you want the most polished app or dependable heart rate during hard workouts, since that is where early reviewers say it slips.
Middle of the pack once you count the years: $597
2. WHOOP 5.0
WHOOP's $199 headline is the most misleading number in this category, because it is a yearly figure standing where a device price usually sits. Per WHOOP the One tier is $199 a year with the band included, so year three costs you exactly as much as year one, and three years is $597. Peak is $717 and Life is $1,077.
What you get for it is the deepest recovery and strain analysis of anything here, 14 or more days of battery, and on-body wireless charging on the Peak and Life tiers so the band never comes off. What you do not get is a screen, ownership, or any data at all once you stop paying. WHOOP also states the Life tier's ECG, AFib and blood pressure features are wellness-only and not FDA-cleared.
Skip it if: the three year total is what you care about, since membership at $199 to $359 a year is the only way to keep one running.
Annual membership, band included
Highest three-year cost of the rings: $608.97
3. Oura Ring 5
The Oura is the best-executed device on this list and the most expensive to own. It is rated 40 percent smaller and thinner than the previous generation, waterproof to 100 meters, quoted at 6 to 9 days per charge, and reviewers have generally rated its sleep staging, HRV and temperature tracking as consistent.
The bill is the problem. Per Oura, without the membership the ring syncs only basic steps, heart rate and temperature, and the Readiness, Sleep and Activity scores, sleep stage breakdown and HRV trends all go away. New Ring 5 buyers get one free month, cut down from the twelve months that shipped with the Ring 4. Budget $608.97 for three years on the annual plan, more if you want a finish other than Silver or Black.
Skip it if: you would resent $5.99 a month on top of the ring price indefinitely, since the useful scores are locked behind it.
The cheapest way out of the ring question entirely: $199.95
4. Withings Sleep
If what you actually want is nightly sleep data rather than a ring, the Withings Sleep pad undercuts every option above. It slides under the mattress, plugs into the wall, and tracks sleep stages, heart rate, respiratory rate and snoring with a pneumatic sensor and a sound sensor. Withings states the core tracking works without the optional Withings+ plan, so the three-year cost is the $199.95 we read on Withings' site on August 17, 2026.
It has real limits. It only works in your own bed, it has no battery so it must stay plugged in, and the US model is not FDA-cleared for sleep apnea detection despite what the name suggests. There is no daytime activity, no HRV-driven readiness score and nothing to wear.
Skip it if: you want daytime or activity data, since it only measures what happens in bed and has to stay plugged in.
Common questions
Which smart ring is cheapest to own over three years?
RingConn Gen 3 at $349, because there is no subscription to add. Oura Ring 5 comes to $608.97 over the same period and the cheapest WHOOP tier comes to $597, both using each company's published pricing and the device prices we verified on August 17, 2026.
Is the Oura membership optional?
Technically the ring still works without it, but per Oura it drops to syncing basic steps, heart rate and temperature. The Readiness, Sleep and Activity scores, the sleep stage breakdown, HRV trends and the personalized insights are all membership features, which is most of the reason people buy the ring.
Why does WHOOP look cheaper than it is?
Because the $199 figure is an annual membership, not a purchase. The band is bundled in rather than sold, so there is no one-time cost to compare against Oura's $399. Multiply by the number of years you expect to wear it and the comparison becomes honest.
Does the subscription price ever change?
It can, and we do not control that. The figures on this page are the published prices at the time of writing, and they are the ones we would want to be judged on. If a company changes its pricing, our math changes with it.
Are any of these medical devices?
No. All of them estimate sleep stages from movement and heart signals rather than measuring brain activity. Withings states the US Sleep pad is not FDA-cleared for sleep apnea detection, and WHOOP states its Life tier heart features are wellness-only and not FDA-cleared. Treat every stage breakdown as a trend rather than a result.
