Buying guide
The best sleep trackers without a subscription (updated August 2026)
Updated Aug 27, 2026 ยท prices dated per offer
Almost every sleep tracker worth buying now comes with a second price tag you do not see on the box. Oura charges a membership to unlock the scores that make the ring useful. WHOOP does not sell hardware at all: you subscribe, and the band arrives as part of the deal. If you stop paying either one, the thing on your finger or wrist stops telling you anything.
Two devices we track break that pattern completely. RingConn Gen 3 and the Withings Sleep pad both include every feature they ship with, forever, for one payment. This guide is about those two, with the subscription-bound alternatives priced honestly next to them so you can see the gap.
Here is the three-year math, using each company's own published pricing. RingConn Gen 3 was $349 on RingConn's site when we checked on August 17, 2026, and RingConn states no subscription is required, so three years costs $349. The Withings Sleep pad was $199.95 on Withings' site the same day, and Withings states core sleep, heart rate and snoring tracking work without Withings+, so three years costs $199.95.
Now the other side. Oura Ring 5 was $399 at Target on August 17, 2026, and per Oura the membership is $69.99 a year with only the first month free on a new Ring 5. That is $399 plus $209.97, or $608.97 over three years. WHOOP has no hardware price: per WHOOP the One tier is $199 a year with the device included, so three years is $597, and the Peak tier at $239 a year comes to $717.
Put plainly, the RingConn costs $259.97 less than the Oura over three years and $248 less than the cheapest WHOOP tier, and the Withings pad costs less than a third of the Oura total. None of these devices is a medical instrument. They estimate sleep stages from movement and heart signals rather than measuring brain activity, and none of the consumer models here is FDA-cleared to diagnose anything.

Best subscription-free tracker
1. RingConn Gen 3
RingConn Gen 3 is the closest thing to a straight swap for a subscription ring. It carries the sensor set you would expect at this price, heart rate, SpO2, HRV, skin temperature and respiratory rate, and RingConn rates it to 10 ATM with a titanium build and a free sizing kit shipped before your real ring. Battery is quoted at up to 14 days, which is roughly double what the Oura is rated for.
The trade is polish. Reviewers describe the app as busier and less refined than Oura's, and heart rate accuracy during hard exercise has been called inconsistent. If you want the prettiest daily readiness score, that is a real cost. If you want your own sleep data to keep working in year four without a card on file, this is the one.
Skip it if: app polish matters to you, since reviewers call it busier and rougher than Oura's, and some Gen 3 features were still rolling out at launch.
Cheapest way to track sleep for free, forever
2. Withings Sleep
The Withings Sleep pad goes under the mattress near chest level, plugs into the wall and tracks sleep stages, heart rate, respiratory rate and snoring using a pneumatic sensor and a sound sensor. There is nothing on your body and nothing to charge, and Withings states the core tracking and nightly Sleep Score work without the optional Withings+ plan.
It only works in the bed it is installed in, it has no battery so it must stay plugged in, and the US model is not FDA-cleared for sleep apnea detection. For $199.95 as read on Withings' site on August 17, 2026, it is the least expensive way onto this list and the only one you never have to remember to wear.
Skip it if: you want anything measured away from the bed, since it needs a wall outlet and only works under a mattress.
The subscription ring, priced honestly
3. Oura Ring 5
We include the Oura Ring 5 because pretending it does not exist would be dishonest. It is the most refined tracker here, rated 40 percent smaller than the previous generation, waterproof to 100 meters, with 6 to 9 days of battery and sleep staging that independent reviewers have generally rated well.
But per Oura the membership is mandatory to get the Readiness, Sleep and Activity scores, sleep stage breakdown, HRV trends and insights, and new Ring 5 buyers now get one free month rather than the twelve that came with the Ring 4. At $399 plus $69.99 a year, three years of ownership is $608.97. That is the number to compare, not the $399.
Skip it if: avoiding a subscription is the reason you are here, since the scores and sleep stages people buy Oura for are membership only.
The subscription-only band, for context
4. WHOOP 5.0
WHOOP is the purest version of the model this guide is about: per WHOOP there is no standalone device purchase at all. You buy a membership starting at $199 a year on the One tier and the band comes with it, with 14 or more days of battery and on-body charging on the higher tiers so it never has to leave your wrist.
The recovery and strain analysis is the deepest set here, which is why it holds on with people who train seriously. It is also the one that goes completely dark the day you stop paying, and there is no screen, so every metric requires opening the app. Three years on the One tier is $597, within $12 of the Oura total.
Skip it if: you want to pay once, since WHOOP sells membership rather than hardware and the band stops working when it lapses.

Common questions
Which sleep trackers have no subscription at all?
RingConn Gen 3 and the Withings Sleep pad. RingConn states all app features are included with the ring, and Withings states its core sleep, heart rate and snoring tracking work without the optional Withings+ plan. Oura requires a membership for its scores, and WHOOP is sold only as a membership.
What does Oura actually cost over three years?
$608.97 at the prices we verified: $399 for the ring at Target on August 17, 2026, plus $69.99 a year for three years per Oura's published membership pricing. Paying monthly at $5.99 works out to $215.64 over 36 months instead of $209.97.
What does WHOOP cost over three years?
Per WHOOP's published tiers, $597 on One at $199 a year, $717 on Peak at $239 a year, or $1,077 on Life at $359 a year. The device is included in all three, and there is no way to buy the hardware outright.
Is the cheaper ring worse at tracking sleep?
No independent lab has published a direct head-to-head accuracy test between RingConn Gen 3 and Oura Ring 5, so anyone telling you one is definitively more accurate is going beyond the evidence. Reviewers generally rate Oura's app and presentation more highly and note RingConn's longer battery life. Both estimate sleep stages rather than measuring them.
What happens to my data if I stop paying Oura or WHOOP?
Per Oura, without a membership the ring syncs only basic steps, heart rate and temperature data, and the scores and analysis disappear. Per WHOOP, the band stops functioning entirely when the membership ends. Neither of those applies to RingConn or Withings.
