Smart tech keeps getting smarter, and the smallest pieces of technology are making big waves. Take smart rings, for example. They are the latest accessory to undergo a smart tech makeover, with health and sleep tracking features, contactless payment options, and more.
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 theOura 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 might be worth considering.
Oura Ring Gen3 specs: Material: Lightweight titanium with non-allergenic, non-metallic inner moldingBattery life: 4-7 daysCharging:Full charge in 20 to 80 minutesCompatibility:iOS and AndroidDurability:Water-resistant up to 328 feetSizing:Free sizing kit with purchase on their site
I 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 me with data. Instead, the Oura prioritized on actionable insights and solutions. For example, the over 50 guided meditation options have helped 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 -- as I'm amazed at how such a sleek device can hold a catalog of information. The ring syncs with Apple Health, and Google Fit, as well as 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 the more 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.

The minimalistic, polished RingPay integrates the ever-helpful contactless payment technology. The ring is faster to use 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 information, website links, and contact information to your friends' devices. Additionally, if you set your name and business credentials as the digital message, it 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.

The Circular Ring 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 with emphasis on quality, duration, and circadian rhythm. You'll even get notifications about irregular heart rates and blood oxygen levels. Plus, the ring promises 10 days of built-in data storage without 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.

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.
Other 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.
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.
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.
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.
Making its debut at CES 2023, Movano Health says its women's health-focused Evie Ring will be available in November 2023.
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:
