The best smart rings you can buy

Forget a smartwatch: The best smart rings track your fitness and health, monitor your sleep, and more in a sleeker manner.
Written by Sherin Shibu, Contributor and  Nina Raemont, Associate Editor

Smart tech keeps getting smarter, and the smallest pieces of technology are making big waves. Take smart rings as a prime example. They are the latest accessory to undergo a smart tech makeover, with health, fitness, and sleep tracking features, contactless payment options, and more. All around your finger. And ahead of the holiday season, they're a great gift for the person who wants to track their health data without the bulkiness of a screen on their wrist. 

If smartwatches aren't your speed, but you still want to keep track of how your body recovers from a workout, your heart rate, and more, a smart ring is a lighter alternative that provides by-the-minute insights on your health. And, because they're wrapped around your finger near larger blood vessels instead of your wrist, some smart ring monitors provide a more accurate picture of your health data than smartwatches do.

The best smart rings, like smartwatches, house a comprehensive suite of health and sleep-tracking features. They take a more discreet, less hindering approach. Some options even include non-health-related NFC features like contactless payment and virtual business card functionality. 

Our tested pick for the best smart ring overall is the Oura Ring 3, thanks to its lightweight fit, quick charges, and impressive health suite. Read on to learn more about the perks of the Oura and which other top smart rings are worth considering.

The best smart rings of 2023

Pros & Cons
  • Lightweight and natural fit
  • Quickly charges
  • Automatic firmware updates
  • Operates in Airplane mode
  • Recurring $5.99/month membership
  • No half-sizes

Oura Ring Gen3 tech specs: Material: Lightweight titanium with non-allergenic, non-metallic inner molding | Battery life: 4-7 days | Charging: Full charge in 20 to 80 minutes | Compatibility: iOS and Android | Durability: Water-resistant up to 328 feet | Sizing: Free sizing kit with purchase on their site

Sherin Shibu, a ZDNET contributor, purchased a Heritage Oura Ring and tested it with weekly activities like strength training, cycling, yoga, and more. Not only was it a capable and accurate tracker, but it didn't overwhelm Shibu with data. Instead, the Oura ring prioritized actionable insights and solutions. For example, the over 50 guided meditation options have helped Shibu to alleviate stress and sleep more soundly. 

Additionally, the simplified overall score appears with a detailed chart monitoring heart rate, body temperature, and blood oxygen levels through the night. The ring also automatically senses when you're stressed and adjusts your activity goals accordingly. 

This comprehensive but simple approach is evident in the ring's form factor and integrations -- it amazed Shibu how such a sleek device could hold a catalog of information. The ring syncs with Apple Health, Google Fit, and iOS and Android apps, allowing you to see your daily and even monthly metrics from your mobile device. 

The downside is that there's a $5.99 per month membership cost to unlock personal insights, like in-depth morning sleep analysis and temperature trend monitoring (which can even predict early stages of illness). Non-paying members, however, only have access to sleep, readiness, and activity insights.

McLear RingPay tech specs: Material: Hypoallergenic ceramic | Compatibility: iOS and Android | Charging: No charging required | Durability: Waterproof | Sizing: Sizes 4.5-16 available; ring sizer available at checkout; free size exchanges

The minimalistic, polished RingPay integrates the ever-helpful contactless payment technology. The ring is faster than contactless alternatives, like unlocking your phone wallet or using a credit card.

The RingPay comes from McLear, the company that built the first NFC (near-field communication or wireless data transfer) ring to unlock doors digitally. Similarly, McLear promises that the ring can unlock your NFC-enabled Android phones and tablets with just a touch from ring to device. You can store and securely share information, including Wi-Fi details, website links, and contact information to your friends' devices. Additionally, setting your name and business credentials as the digital message can serve as the ultimate hands-free networking device when held to someone else's device. 

McClear's website says the ring is set to release in the UK first but will quickly launch in other areas, offering an option to join the waitlist

Pros & Cons
  • Four interchangeable outer shells
  • Monitors blood oxygen and heart rate
  • Future firmware updates included in purchase
  • Requires charging

Circular Ring tech specs: Material: Hypoallergenic material with interchangeable outer shells | Battery life: Four days | Charging: 60 minutes | Compatibility: iOS and Android | Durability: Water resistant | Sizing: Sizing kit available for purchase

The Circular Ring was launched last year, and the company markets the ring as "the most advanced wearable tracking device."

The ring focuses on three main components: Sleep, activity, and health. The device tracks precise heart rate, breathing rate, blood oxygen levels, temperature, and motion during sleep while emphasizing quality, duration, and circadian rhythm. You'll even get notifications about irregular heart rates and blood oxygen levels. Plus, the ring promises ten days of built-in data storage without a Bluetooth connection. 

For fitness, you'll get an energy score that tells you how much energy you've exerted throughout the day, and the ring automatically tracks your workouts. The technology organizes data in an easy-to-read app so you can better understand your habits and make better health decisions.

The Hecere NFC ring is the best smart ring for tech-savvy people who may want to use their ring to open their phone or even as a networking tool. It's delivered blank with a built-in rewritable chip. You can download an NFC app for free and program the ring to function however you want, whether you want the ring to turn on Wi-Fi, make a call, or share a contact.

The sensing technology in this ring is more advanced than that in comparable products. If you want a fun, customizable project, this could be the ring for you.

You can share data with family members on the app to learn more about their sleep habits, and even download your sleep reports as Excel files to show your medical provider.

The Go2sleep ring automatically syncs with the Health app on iOS devices, and it features a ring-finding function so you can locate the device if it's misplaced.

Below, our table helps you determine the right ring for you based on specific uses:

How did we choose these smart rings?

I analyzed the overall quality and functionality of smart rings on the market right now. I took into account factors such as pricing, specific purposes, durability, and device compatibility.

  • Purpose and functionality: Traditionally, smart rings like Oura are a substitute for a smartwatch or other health tracking device. We considered rings that did monitor factors like blood oxygen testing, sleep and heart rate tracking, and activity metrics but also considered rings with smart nuances, such as NFC readings and making contactless payments. 
  • Durability: To go from jewelry accessory to smart staple, there are certain durability aspects these rings should include to maximize benefits. We considered if the rings were waterproof, water-resistant, or coated with any extra protection.  
  • Device compatibility: Unlike a smartwatch, smart rings don't have an interactive display. Therefore, all the data is housed via a third-party software. We made sure these choices were compatible with some tech fan favorites such as iOS and Android. 
  • Design: One of the benefits of a smart ring is that, ideally, it's sleek, subtle, and comfortable to wear -- even as your finger may swell in the summer heat. 

Which is the best fitness ring?

Other ZDNET experts also assessed the Oura Ring 3 as the best overall smart ring in the fitness wearable market, especially if your goal is to specifically track exercise and workout recovery. 

Can the Oura ring tell if you're sick?

Yes, by measuring heart rate variability (HRV), the Oura Ring 3 has also proven to show early signs of sickness. Wake Forest University's Dr. Jason Fanning, for example, saw that his "heart rate variability went through the floor" thanks to his Oura Ring data, days before he tested positive for COVID-19. 

Are smart rings reliable?

Smart rings can provide more accurate readings than smartwatches because they are worn close to large blood vessels located in the fingers. In contrast, smartwatch sensors utilize small capillaries for readings. 

What can a smart ring do?

Smart rings can be useful for a variety of functions. A ring like the McLear RingPay is ideal if contactless payments are your top priority. If you want 24/7 monitoring of your blood oxygen and heart rate, go with the Circular Ring. Smart rings can go as far as you need, and you can even program your own with the Hecere NFC Ring.

Smart rings also tend to have long battery lives, while some don't require charging at all.

When does the Evie ring come out?

The Evie Ring is now available to order, and it ships in January 2024. 

Are there alternative smart rings worth considering?

There are various smart rings on the market that didn't make the cut for my top five. However, I've included a few other smart rings that receive honorable mentions:

BodiMetrics Circul Plus Sleep & Fitness Ring

This smart ring offers fitness tracking tools and a waterproof body to withstand sweat, according to longtime ZDNET contributor, Matt Miller.
