The best fitness rings to track your health metrics without the bulk

The top fitness rings are subtler and lighter than your average smartwatch and keep track of your health data -- all from your finger. And our top pick is on sale for Black Friday.
Written by Allison Murray, Staff Writer

If you love to track your steps, keep a careful eye on your health and sleep data, or plan workout regimens with the help of smart tech, you probably have a smartwatch or health wearable. But let's be honest: some smartwatches are far too clunky, and even the most nondescript smartwatch bands can clash with your outfit. 

Smart rings, on the other hand, are a subtler, lightweight, and newer form of wellness tracking that could be up your alley. Thanks to built-in sensors that measure aspects like heart rate and blood oxygen levels, fitness rings continue to revolutionize the fitness wearable landscape, enabling users to track their health and improve their fitness without needing to open their phone or-- in some cases -- wait solely on doctor results. Plus, instead of presenting a screen interface, fitness rings connect via a smartphone app, making for a more distraction-free approach to health and technology.

ZDNET went hands-on with our top pick, the ever-popular Oura Ring Gen 3 Horizon, and we were impressed by its comprehensive health suite, easy wear, nice material, and battery life. (Plus, it's on sale right now ahead of Black Friday.) It's a big year for fitness rings, with two highly anticipated options coming out within the next few months. Find out how other leading brands on the market -- both those currently available and those set to release soon-- compare based on that criteria and more.

Oura Ring Gen 3 Horizon specs: Sizing: 6-13 | Material: Durable titanium and PVD coating | Colors: Silver, black, stealth, gold, rose gold | Water resistance: Up to 328 feet | Sensors: Heart rate, blood oxygen, PPG, skin temperature, 3D accelerometer | Connectivity: Bluetooth Low-Energy, Airplane Mode | Battery: Up to seven days

The Oura Ring is currently one of the most successful fitness rings on the market, offering four different color options and various sizes to choose from.

ZDNET's Sherin Shibu bought and tested the Heritage Oura ring, and put it through a number of weekly activities, like strength training, cycling class, yoga class, and more. The highlight of the ring is that it doesn't let the user get lost in data. You get a simplified activity, sleep, and readiness score that you can use to improve your overall wellness, along with more detailed charts monitoring heart rate and body temperature if you wish to peruse them.

Review: Is the Oura Ring worth buying in 2023?

The ring also has exceptional sleep tracking. It provides insightful data that surpasses what you would receive from a Fitbit or the best smart rings. For instance, it displays your HRV balance, temperature changes during sleep (which can be used to predict menstrual cycles), blood oxygen levels, and the duration of each sleep stage.

In addition to its impressive sleep tracking, the Oura Ring also excels in activity tracking. It monitors your steps, calories burned (including active calories), heart rate during exercise, and training volume. When comparing its activity tracking to that of a Garmin Vivomove Sport watch, the Oura Ring was within 200 steps of Garmin's tracked steps.

In 2022, Oura introduced the Horizon model, which removes the flat spot at the top of the ring to make it entirely round like a regular ring. You can opt for the Heritage model, which starts at $299, or the new Horizon model which starts at $349.

Pros & Cons
  • Affordable
  • 'Find the Ring' feature
  • Heart rate, HRV, and blood oxygen sensors
  • No exercise data
  • Some inaccuracies reported

Vibrations and reminders in a fitness ring.

It tracks precise heart rate, breathing rate, blood oxygen levels, temperature, and motion during sleep with emphasis on quality, duration, and circadian rhythm.

How did I choose these fitness rings?

There are several factors we considered when evaluating the best fitness rings. 

  • Material: The ring's composition matters because it helps determine how heavy the ring will be on your finger. Most rings weigh about four to six grams, depending on your ring size, and are often made of durable, lightweight titanium.
  • Battery: You want to be sure that you can enjoy your ring properly, so we consider how long the battery will last before it needs another charge.
  • Features: Many of the best fitness rings include special features, like a sleep tracker, period predictor, and fitness tracker. These extra features can help you improve your health by keeping you informed and identifying your trouble areas. You typically can access these stats via a companion app.
  • Price: The cost of fitness rings can vary significantly. Our picks for the best fitness rings range in price from $100 to about $400, depending on the model and features you choose.  

When shopping for the best fitness rings, consider which features are most important to you and be sure to explore your options so you can find the best fit for your needs.

What are fitness rings, and how do they work?

A fitness ring is also known as a smart ring. Similar to a smartwatch, this is an electronic device that you wear around your finger to monitor your health and activity. It uses sensors and special chips to track and store your information. Some models offer water resistance so you can wear them as you swim, while others provide alerts via vibration for alarms, personal reminders, and more. 

Is Oura Ring better than an Apple Watch?

That really depends on if you're a watch person or a ring person. The Apple Watch lets you see all your stats on the watch itself and has features like texting and streaming music. 

On the other hand, the Oura Ring is more of an ambient technology that you forget you're wearing. You have to go into the app to get your stats, and it doesn't have any fancy notifications. However, the Oura Ring will track your sleep more accurately than the Apple Watch, and it's comparable to Apple Watch's activity tracking.

Are fitness rings accurate in tracking activity, sleep, and other health metrics?

Fitness rings can provide reasonably accurate data on health metrics like heart rate, steps taken, and sleep patterns. However, the accuracy of each metric can vary depending on the specific device and the quality of the sensors used. It's essential to choose a fitness ring with reliable sensor technology and to keep in mind that no wearable device can provide perfect accuracy in tracking health metrics.

Are there alternative fitness rings worth considering?

The fitness ring market is small, but it is growing. There aren't many other options to choose from at the moment, but we'd recommend checking out these picks as well.
