Best Smart Rings 2026: 6 Picks, With and Without a Subscription

This article contains affiliate links: if you buy through them we may earn a commission, at no extra cost to you. Learn more.

The best recovery data comes from the hours you’re not thinking about it: the night after a tournament, the sleep before a long ride, the week your swim volume doubled. A smart ring collects it quietly, with nothing on your wrist, no strap to tighten and nothing to snag in a scrum or under a boxing glove wrap. Choosing the best smart ring in 2026 comes down to three things: how well it tracks sleep and recovery, how long the battery lasts, and whether you’ll pay a monthly fee. Here are six rings worth buying, how they compare, and who each one suits.

Prices change often. The prices below are what we saw at the maker or a major retailer in October 2026; check the current price before you buy.

The best smart rings

1. Oura Ring 5: best overall

Oura’s fifth ring, launched in May 2026, is about 40% smaller than the Ring 4: 6.09 mm wide, 2.28 mm thick and as light as 2 g, in titanium, waterproof to 100 m. It measures heart rate, HRV, skin temperature and blood oxygen and turns them into Readiness, Sleep and Activity scores, plus stress, cardiovascular and cycle insights. Oura rates the battery at 6 to 9 days depending on size. Silver and Black cost $399; Gold, Deep Rose, Stealth and Brushed Silver cost $499. The full app needs a membership: $5.99 a month or $69.99 a year, with the first month free.

• Good: the most refined app and sleep tracking; tiny and easy to forget; 100+ app integrations.
• Watch out: the membership adds about $70 a year; the optional charging case is $99 extra.
• Best for: athletes of any sport who want the best sleep and readiness data and don’t mind the fee.

2. RingConn Gen 3: best with no subscription

RingConn’s Gen 3 launched in May 2026 and is the strongest ring here if you never want a monthly bill. It adds a vibration motor that can nudge you about a high heart rate, a step goal or a low battery. RingConn rates the battery at up to 14 days (11 to 14 with vibrations off, 10 to 12 with them on), and a charging case comes in the box. It tracks sleep, HRV, heart rate, blood oxygen and stress, and offers sleep apnea pattern insights and vascular trends. It’s titanium, water resistant to 100 m, works with iPhone and Android, and costs $349 ($369 for premium colors).

• Good: no fees; two weeks per charge; a case for travel and tournament weekends.
• Watch out: Gen 3 sizes differ from earlier RingConn rings, so use the sizing kit; blood pressure features were announced for a later update.
• Best for: anyone who wants Oura-style tracking without the subscription.

3. Ultrahuman Ring Pro: best battery life

Ultrahuman’s earlier Ring Air was pulled from the US after a 2025 patent ruling won by Oura. The redesigned Ring Pro cleared US Customs in March 2026 and began shipping in mid-2026. Ultrahuman rates it at up to 15 days per charge (about 12 in its higher-power mode) and up to 45 days with the PRO Charging Case. It’s titanium, water resistant to 100 m, comes in sizes 5 to 14, and stores up to 250 days of data on the ring. Core sleep, recovery, movement and stress insights need no subscription; optional “PowerPlugs” add-ons are free for the first year, with later pricing not published. Ultrahuman’s store sells the ring with the PRO Charging Case for $479; other bundles and launch prices vary.

• Good: the longest battery of any ring here; no core fees.
• Watch out: priciest bundle; check whether the case is included in the offer you see.
• Best for: endurance athletes, travelers and anyone who hates charging.

4. Samsung Galaxy Ring: best for Android and Samsung phones

Samsung’s ring weighs 2.3 to 3.0 g, is 7.0 mm wide and 2.6 mm thick, and is rated IP68 and 10 ATM. It tracks heart rate, HRV, skin temperature and sleep, detects walks and runs automatically, and feeds Samsung Health’s Energy Score. Samsung says the battery lasts up to 7 days (smaller sizes get less), and every ring comes with its own charging case. There’s no subscription. It needs an Android phone, and some AI features work best with a Samsung Galaxy phone. It costs $399.99 in sizes 5 to 15.

• Good: no fees; case included; fits neatly with a Galaxy phone and watch.
• Watch out: no iPhone support; shorter battery than RingConn or Ultrahuman; launched in 2024, so it’s the oldest design here.
• Best for: athletes already living in Samsung Health.

5. Circular Ring 2: best for ECG and extra data

Circular’s second ring is the one for data lovers. It adds a single-lead ECG (a 40-second reading) to the usual heart rate, temperature and motion sensors, and estimates blood pressure from ECG and pulse timing after you calibrate it with your own cuff. Circular rates it at 8 days in power mode and 4 to 5 in performance mode, and it charges in about 30 minutes in its wireless case. It’s titanium, 4 g, 2.55 mm thick, IP68, in US sizes 6 to 14, for iPhone and Android, with no mandatory subscription. It costs $349 on Circular’s store.

• Good: ECG on a ring; fast charging; no required fees.
• Watch out: heavier and thicker than the Oura Ring 5; a smaller company, so check shipping times and the 14-day return window.
• Best for: curious athletes who want more metrics to explore.

6. Amazfit Helio Ring: best budget smart ring

The Helio Ring launched at $299 and now sells for far less: we saw about $149.99 at Amazfit and about $199 quoted in reviews. It’s titanium, water resistant to 100 m, and tracks sleep, heart rate, HRV and readiness in the free Zepp app, with an EDA sensor for stress. There’s no subscription. The catch is battery: up to about 4 days, the shortest here. It makes most sense as a sleep tracker next to an Amazfit watch you wear for training.

• Good: lowest price; no fees; pairs with Amazfit watches.
• Watch out: short battery; Amazfit uses its own ring sizes, so get the sizing kit; stock varies by size.
• Best for: trying a smart ring without spending $300+.

How to choose a smart ring

• Size before you buy. Every brand uses its own sizes and most send a free or cheap sizing kit. Wear the sample for a full day and night, including a workout; fingers swell after training and in heat.
• Count the subscription. Over three years, Oura’s membership adds about $210. RingConn, Samsung, Ultrahuman (core features), Circular and Amazfit add nothing.
• Check your phone. The Galaxy Ring is Android-only; the others work with iPhone and Android.
• Plan for the gym and the court. Barbells, kettlebells, climbing holds, racquets and gloves scratch rings and can pinch. Many lifters, climbers and fighters move the ring to another finger or take it off for the session and put it back on for sleep.
• A ring is not a training watch. Rings are best at sleep and recovery. If you pace runs, rides or swims live, pair the ring with a watch or see our Whoop vs Oura vs Garmin comparison.

Smart rings are consumer wellness devices, not medical devices for diagnosis or treatment. Features like ECG, blood pressure estimates or sleep apnea insights don’t replace a doctor; if you have a heart condition or other health concern, talk to your doctor.

Smart ring questions

Which smart rings have no subscription?

RingConn Gen 3, Samsung Galaxy Ring, Circular Ring 2 and Amazfit Helio Ring have no required subscription. Ultrahuman Ring Pro has none for core features, with optional paid add-ons after the first year. Oura needs a membership for the full app.

Is the Oura Ring 4 still worth buying?

It can be, at a good discount. Oura says most new software features work on both rings. The Ring 5 is smaller and lighter and lasts a bit longer (6 to 9 days versus 5 to 8), but both need the same $5.99 membership.

Which finger should I wear a smart ring on?

The one where it fits snugly without spinning; many people choose the index finger. Size for that exact finger with the kit, and pick your non-dominant hand if you lift or play racquet sports.

Can I swim with a smart ring?

Oura Ring 5, RingConn Gen 3, Ultrahuman Ring Pro and Amazfit Helio Ring are rated to 100 m; the Galaxy Ring is rated 10 ATM and the Circular Ring 2 IP68. Rings track your recovery from swimming well, but don’t expect lap counts.

Is a smart ring better than a Whoop?

It’s different. A ring is easier to sleep in and looks like jewelry; a band like WHOOP gives better day-long strain tracking and can be worn on the upper arm for lifting. Our Whoop vs Oura vs Garmin guide compares them side by side.
