Technology has transformed watches from traditional wristwatches to smart tracking devices straight out of a James Bond movie. Lately, rings are the latest jewelry staple to get a smart makeover.

The best smart NFC rings, like smartwatches, have a comprehensive suite of health and sleep tracking features. They take a more cautious (and even less obstructive) approach, especially ahead of summer sports and social events. Some options even include non-health-related NFC functionality, like contactless payments.

Our overall pick for the best smart ring we tested is the Oura Ring 3, thanks to its impressive health suite. Read on to learn more about the benefits of Oura, and which other top smart rings might be worth considering.

I purchased a Heritage Oura ring and put it to the test with weekly activities such as strength training, cycling, yoga, etc. Not only did it adequately track my activity, sleep, and daily readiness, but I didn’t get lost in an overwhelming amount of data. Instead, my morning sleep score is actionable and provides insight into how I can improve my nighttime habits.

For example, over 50 guided meditation options help me relieve stress instantly and set me up for sleep success. A simplified overall score will be displayed as a detailed graph, monitoring nightly heart rate, body temperature and blood oxygen levels. Plus, the ring can automatically sense when you’re feeling stressed and adjust what Oura calls the activity’s “daily readiness score” accordingly.

This comprehensive yet simple approach is evident in the form factor and integration of the ring. I’m also amazed at how all the (accurate) tech fits into such a small, sleek device. Also, even with the lights turned off at night, I don’t notice the red and green sensor lights. The ring syncs with Apple Health, Google Fit, and the iOS and Android apps. This compatibility means you can see daily, weekly and monthly views of activity and other metrics.
The downside is that there is a $5.99 monthly membership fee to unlock the features that make this ring worth the money, such as in-depth morning sleep analysis, blood oxygen monitoring, real-time heart rate and temperature trend monitoring (it can even predict the early stages of disease), and overall personalized insights. However, non-paying members only have access to sleep, readiness, and activity insights.

How did we choose these smart rings?

I analyzed the overall quality and functionality of smart rings currently on the market. I considered factors such as pricing, specific use, durability, and device compatibility.

Use and function: Traditionally, smart rings like the Oura are replacements for smartwatches or other health-tracking devices. We considered rings that do monitor things like blood oxygen tests, sleep and heart rate tracking, and activity metrics, but also rings with smart nuances like NFC readouts and contactless payments.

Durability: From jewelry accessories to smart staples, these rings should include certain aspects of durability to maximize benefits. We considered whether the ring is waterproof, waterproof or coated for any additional protection.

Device Compatibility: Unlike smart watches, smart rings do not have an interactive display. Therefore, all data is stored via third-party software. We’ve made sure these picks are compatible with some tech fan favorites like iOS and Android.

Design: One of the great things about a smart ring is that, ideally, it’s sleek, subtle, and comfortable to wear—even if your fingers can get swollen on a hot summer day.

Which Is The Best Fitness Ring?

Other experts on the FuninUSA.NET editorial staff also named the Oura Ring 3 the best overall smart ring in the fitness wearable market. If your goal is to specifically track workouts and workout recovery, Oura Ring 3 is the best choice for you. 


Effective in measuring heart rate variability (HRV), Oura Ring 3 has also been shown to show early signs of disease. For example, Dr. Jason Fanning of Wake Forest University saw his “heart rate variability go through the floor” days before he tested positive for COVID-19 thanks to his Oura Ring data.

Oura even partnered with the NBA to help players train during the pandemic. The NBA purchased 2,000 Oura rings to track signs of COVID-19 symptoms using body temperature data. Additionally, the smart ring provides players with personalized insights into their health.

As such, the Oura has proven to be a solid choice when it comes to fitness reliability.

Are smart rings reliable?

Smart rings can provide more accurate readings than smart watches because they are worn near the large blood vessels on the finger. In contrast, smartwatch sensors utilize small capillaries for readings.

What can a smart ring do?

Smart rings can be used for various functions. A ring like the McLear RingPay is ideal if contactless payments are a priority for you. Use the circular ring if you want to monitor your blood oxygen and heart rate 24/7. The smart ring can go as far as you want, and you can even program your own ring with the Hecere NFC Ring.

Smart rings also tend to have long battery life, and some don’t need charging at all.
