Best smart rings in 2026: how to choose, and six worth a look

The best smart ring for most people depends on two things before anything else: the phone you carry and whether you'll pay a monthly fee. Oura Ring 5 has the most developed app but requires a membership for most of it. The other five rings in this guide charge nothing after purchase, and one of them, Samsung's Galaxy Ring, works only with Android.

How we chose

This guide is spec-based. We compared each ring using the company's published specifications, US prices and help pages as of Oct. 25, 2026, and we cite outside reviews where they add something. We haven't tested these rings ourselves. We looked at:

• Phone compatibility, since a ring that doesn't work with your phone is a non-starter.
• Total cost, including any subscription over two years.
• Rated battery life and how charging works.
• Size range, because each brand sizes differently and some stop at 13 or 14.
• Distinctive health features, such as an ECG or vibration alerts.
• Availability risk: Oura has sued several rivals over patents, and one of those cases targets a ring on this list.

The six rings at a glance

Oura Ring 5: the most complete app

Oura's current ring starts at $399 in Silver and Black and $499 in four other finishes, according to CNET. Oura calls it the world's smallest smart ring, at 6.09 mm wide and 2.28 mm thick, and rates it for six to nine days per charge. It tracks more than 50 metrics, and the membership adds a long list of features: Health Radar for longer-term signals like nighttime breathing, an AI assistant called Oura Advisor, GLP-1 medication insights and, in the US, $99 blood tests through the app. Wired's reviewer, who has used rings from all the big brands, wrote that Oura "delivers the strongest software experience."

The trade-offs are the membership, $5.99 a month or $69.99 a year in the US, without which the app shows only three daily scores; a size range of 6 to 13; and a $99 charging case sold separately. If you need a size outside that range, Oura's previous Ring 4 covers 4 to 15, subject to inventory. Our Oura Ring guide has the details.

Samsung Galaxy Ring: for Samsung phone owners

The Galaxy Ring launched in July 2024 at $399.99 and is now listed from $299.99 on Samsung's US store, with no subscription. It comes in the widest size range here, 5 to 15, and includes a charging case with its own battery. Samsung rates it for up to seven days in sizes 12 and 13 and up to six in smaller sizes.

It needs an Android phone, and several features, including gestures, Find My Ring and the Energy Score, need a Samsung Galaxy phone. Samsung hasn't updated the hardware since launch, and its components can't be replaced. Our Galaxy Ring guide covers compatibility in depth.

Ultrahuman Ring Pro: the longest battery of the big names

Ultrahuman's titanium Ring Pro costs $479 in the US with its PRO Charging Case, which holds up to 45 days of extra power and a year of data. Ultrahuman rates the ring itself for up to 15 days. It works with iPhone and Android, stores up to 250 days of data on the ring and needs no subscription, though Ultrahuman sells optional paid add-ons and an Ultrahuman Max plan from $9.99 a month.

It is heavier than Oura's ring, at 3.3 to 4.8 grams. And Oura filed suit on Oct. 22 asking a court to stop US sales over two patents, TechCrunch reported; no order has been issued and Ultrahuman says the ring remains on sale. Our Ultrahuman Ring Pro guide explains the dispute.

RingConn Gen 3: long battery and vibration alerts

RingConn's newest ring, unveiled at CES 2026, is listed at $428 on RingConn's US store and needs no subscription. RingConn rates it at 11 to 14 days per charge, or 10 to 12 days with vibration turned on. It also vibrates, buzzing for health changes, sedentary reminders and low battery, though RingConn says it doesn't vibrate for messages or alarms.

The Gen 3 also adds vascular health trends, which RingConn says are trend insights, not single blood pressure readings, and sleep apnea pattern insights. It is 2.3 mm thick, weighs 2.5 to 3.5 grams, comes in sizes 6 to 15 and syncs with Apple Health and Google Health Connect. RingConn pays Oura royalties under a licensing deal, according to TechCrunch.

RingConn Gen 2 Air: the budget pick

At $238, the Gen 2 Air is the cheapest ring here. RingConn rates it at up to 10 days per charge, with no subscription. It is 2 mm thick, weighs 2.5 to 4 grams, is water resistant to 100 meters and comes in sizes 6 to 14. RingConn describes it as an entry-level ring with the core health features. It charges on a dock rather than in a battery case, and it stores five to seven days of data when it can't sync.

Circular Ring 2: an ECG on your finger

The Circular Ring 2, from a company that says its rings are designed in Paris, costs $349 and is the only ring here with an on-demand ECG: a 40-second reading taken finger to finger, with signs of AFib flagged by an algorithm Circular says is FDA cleared. Circular is also rolling out blood pressure readings that you calibrate once with a cuff; it says they track trends against your own baseline and don't replace a cuff or count as a diagnosis.

Circular rates the ring at seven days per charge. It weighs 4 grams, is water resistant to 50 meters and works with iOS 15 or later and Android 9 or later. Core features and its AI coach, Kira, are included, with optional Pro features in the app, and a built-in haptic motor works as a silent alarm. Like RingConn, it pays Oura royalties, according to TechCrunch.

How to decide

• iPhone user who wants the most features: Oura Ring 5, if the membership doesn't bother you.
• iPhone user who won't pay a subscription: Ultrahuman Ring Pro or RingConn Gen 3, or the Gen 2 Air on a budget.
• Samsung Galaxy phone owner: the Galaxy Ring, which has no fee and unlocks its full feature set on your phone.
• You care most about heart rhythm: Circular Ring 2, for its ECG.
• You hate charging: Ultrahuman Ring Pro or RingConn Gen 3.

Whichever you choose, order the brand's sizing kit first; our smart ring sizing guide explains why. And if you're still deciding between a ring and a watch, see our smart ring vs smartwatch guide.

Returns and warranties

Sizing mistakes happen, so check the return window before you order. Oura allows one return or exchange per ring, with refunds within 30 days. RingConn lists 14-day returns and exchanges and sells optional coverage plans of one year for $29.99 or two years for $49.99. Circular allows returns within 14 days, with the customer paying return shipping, and includes a one-year warranty. Check Samsung's and Ultrahuman's current terms at checkout.

Rings we left out

The Ultrahuman Ring Air isn't sold in the US, according to Ultrahuman. Amazfit's US store page for its Helio Ring now shows the company's Helio Strap, an armband-style tracker, so we couldn't confirm the ring is still sold there. Oura Ring 4 remains an option where stock exists, mainly for people whose size falls outside Ring 5's range.
