Smart ring reviews for people who'd rather own than subscribe

Smart rings you own outright. No monthly fee.

The leading smart rings, from Oura, Samsung, RingConn and Ultrahuman, compared on what they cost to own over three years, what published studies say about their accuracy against a chest strap, and the battery and sizing fine print.

What it really costs

The fee is the part nobody puts on the box

Oura charges $5.99 a month or $69.99 a year for its membership in the US, and without it the app shows only three daily scores. That's $209.97 over three years on the annual plan, on top of the ring. The rings below charge nothing to see your own data.

#ad · Fees are each brand's published US plan price, checked Sep 19, 2026, multiplied out on the cheapest billing option offered (annual where it exists), ignoring any included free month and sales tax. Your total is the ring price plus the fee column. Ring prices change daily, so we link to the live price instead of printing one. How we compute fees.

Why trust these picks

What we do differently

  • Cost to own

    The fee, multiplied out

    Every subscription is quoted from the brand's own policy page with the date we checked it, then multiplied over one, three and five years. The arithmetic is on the page so you can repeat it.

  • Evidence, not vibes

    Accuracy from named studies

    When we say a ring is accurate, we name the study, the reference device (chest strap, ECG or sleep lab), the sample size and who paid for it. Brand-funded and preprint data are labeled as such.

  • Check it yourself

    A chest-strap test you can run

    Our do-it-yourself protocol shows how to compare your own ring against a chest strap over a week of nights, and what size of difference is normal.

  • Honest labels

    No fake “we wore it” claims

    Every pick is labeled Researched and scored on a public rubric. Maker battery and accuracy numbers are marked as the maker's claim. Where a figure isn't published, we say so.

How this site is funded

We earn from Amazon. It never picks the winner.

As an Amazon Associate, Ring & Rest earns from qualifying purchases when you buy through our links, at no extra cost to you. No brand pays for placement, and two of the rings we rank (Ultrahuman and Circular) earn us nothing at all because they aren't sold on Amazon. Scores come from the published rubric, set before any link is added. Updated September 2026.
