With the Helio Ring, you’ll be able to track key sleep metrics, including sleep quality and its stages, breathing, heart rate variability, and resting heart rate. Each morning, you’ll receive a readiness score to gauge how well you rested — this score is intended to help you decide if you are fully recovered or if you could use a bit more rest before another workout.

The makers of the ring also theorize that the mind is just as important as the body for athletic performance and for this reason the Helio Ring includes an electrodermal activity (EDA) sensor as an additional feature to monitor stress levels, which it combines with heart rate variability data.

How have we compiled the best smart rings?

When compiling this list of the best smart rings available on the market, we considered multiple criteria. So, should the idea of owning a smart ring ever cross your mind, the following points would come in handy:

Features and functionalityDesign and comfortBattery lifeCompatibilityWater resistance
Widely adopted metricsAesthetic and fittingLong-lastingCompatible with your smartphone's operating systemIP68, IP67, or other
  • Features and functionality. When it comes to the best smart rings, their value truly stems from the features they offer. Therefore, we sought out those that could track your sleep, measure heart rate, and provide insights, among other functions.
  • Design and comfort. With design and comfort going hand in hand in creating a wearable accessory, we made an effort to include those best smart rings in our list, which strike a balance between aesthetic appeal and fit.
  • Battery life. Considering that battery life significantly influences how seamlessly the smart ring blends into your daily routine, our top priority has been to include health rings that can run for several days or even up to a week on a single charge.
  • Compatibility. Given the importance of compatibility, especially in terms of how effectively the smart ring integrates with your current devices, we have opted for smart rings that support the traditional smartphone operating systems — iOS and Android.
  • Water resistance. For wearable technology, smart rings in particular, water resistance holds paramount value as it allows them to withstand exposure to water during your everyday activities. All the best smart rings on our list are water-resistant, with some featuring commonly used ratings like IP67 and IP68.

Researcher’s insights

To get further insights on smart rings, we turned to our in-house researcher, Dominyka Sitavičiūtė, who gladly shared her insights and tips with our readers.

Are smart rings worth it?

Despite their small size, smart rings pack an impressive range of features to track various physiological metrics such as heart rate, daily physical activity levels, body temperature, respiratory rate, sleep patterns, and more.

However, it is essential to approach these devices with the right expectations. While they can provide some insights into general health and fitness trends, smart rings, or other similar consumer-grade wearables, are not substitutes for medical devices.

Health Content Researcher

What to avoid?

The FDA has issued a warning on smartwatches and rings that claim to measure blood sugar levels. The warning states, “These devices are different than smartwatch applications that display data from FDA-authorized blood glucose measuring devices that pierce the skin, like continuous glucose monitoring devices (CGMs).

The FDA has not authorized, cleared, or approved any smartwatch or smart ring that is intended to measure or estimate blood glucose values on its own.” Hence, they are best to avoid.

For individuals with diabetes, it is especially important to avoid relying on these devices for blood glucose measurements. Inaccurate readings can result in significant errors in diabetes management, such as administering incorrect doses of glucose-lowering medications, namely, insulin.

Inadequate dosing of such medications can cause blood sugar levels to drop to dangerously low levels, potentially leading to severe consequences like confusion, loss of consciousness, coma, or even death within hours. This once again highlights the point that smart rings should not be regarded as dependable tools for managing serious health conditions.

How smart rings enhance daily productivity

Worn on your finger like traditional rings, smart tech rings are next-generation self-tracking devices that integrate technology into everyday life. They have the potential to enhance daily productivity by simplifying everyday tasks and keeping you connected to sensitive information, all without disrupting your routine.

These small yet powerful gadgets encompass a range of functionalities and feature packages. Offering quick access to vital information and real-time updates, these rings can monitor heart rate, sleep patterns, fitness performance, and more, depending on the technology supported by the smart ring.

Smart rings for health typically come in various sizes and designs, with some even offering additional customization options, including different outer shells. As for charging, methods may vary depending on the model. However, smart rings usually use wireless charging. This involves placing the ring on a charging dock or pad connected to a power source.

How does a smart ring work?

At its core, a smart ring is a wearable device embedded with a plethora of sensors, including, but not limited to, green LEDs for heart rate, red LEDs for blood oxygen, and infrared Photoplethysmography (PPG) sensors, among various others.

Offering compatibility with the widely used operating systems — iOS and Android — most smart rings establish connections via Bluetooth. This seamless connection allows them to sync with smartphone applications, offering detailed insights into daily activity, heart rate fluctuations, and sleep patterns.

With smart rings, personalized health tracking becomes an integral part of daily life, allowing for effortless data-centric access to information that holds personal importance.

Features and benefits of smart rings

Engineered to seamlessly integrate into your daily routine, smart rings come packed with an array of features and benefits. Further below, we delve deeper into the primary benefits associated with these smart rings.

  • Heart rate monitoring. Continuous heart rate monitoring can help you identify trends and understand how different activities or stressors affect your heart rate.
  • Sleep monitoring. Smart rings can analyze your sleep patterns, including the stages and quality of your sleep. This allows you to take the necessary measures and make adjustments for better sleep practices.
  • Activity tracking. With the functionality to count your steps, measure distances traveled, estimate calories burned, and provide activity reports, the best smart rings assist you in both tracking your progress and adopting a somewhat more active lifestyle.
  • Stress levels. By continuously monitoring pressure levels during work or daily activities, smart rings have the capability to offer insights into your stress levels. They can then send alerts, prompting you to take a break, recalibrate your emotional state, and start practicing relaxation techniques.
  • Personalized insights. From data analysis and behavioral patterns that can reveal your most active times of the day or the impact of certain activities on your heart rate, to predicting fertility windows, smart rings are adept at delivering personalized insights.

Smart rings for fitness tracking

Given that the finger is an ideal source for accurate heart rate data due to its sensitivity to movement and accuracy across all skin types, smart fitness rings provide a convenient method to track your fitness and health metrics throughout the day.

Their subtle design and smooth integration with apps make smart rings that track health serviceable companions for workouts. Typically featuring built-in sensors, these rings provide real-time insights and personalized feedback, which, in the end, may assist you in achieving your fitness goals.

Oura ring alternatives

As praised as the Oura smart ring is for being one of the best tech rings to ever hit the market, it might not be the ideal choice for everyone. Now, if that person happens to be you, fear not — there are several Oura ring competitors in 2025. ​​From fitness rings to those rings that monitor health and even blood pressure rings, the options are diverse and plentiful. Those who prioritize specific features may be drawn to products like Sleepon's Go2sleep, with its detailed minute-by-minute sleep reports, or Circular Ring Slim, designed to be worn constantly without you even noticing it.

Additionally, given the steep price point of the Oura ring, those mindful of costs may be steered toward the affordability of cheaper Oura ring alternatives like RingConn and Ultrahuman. These two top-tier tech rings offer impressive health-tracking features in their own right without straining your budget as much.

Are smart rings safe to wear?

Smart rings are created with user safety in mind and subjected to testing to meet safety standards before entering the market. However, as with any wearable technology, smart rings should be approached with caution. Users should consider allergies, proper sizing, and skin sensitivity before proceeding with a purchase.

In the grand scheme, smart rings can be safely integrated into everyday life by choosing a reputable brand, following instructions, and monitoring individual responses.

Are there different sizes available for smart rings?

Much like traditional rings, smart rings that monitor health are produced in various sizes to guarantee a comfortable and secure fit for a diverse range of users. When searching for a smart ring, you will usually encounter sizing choices that align with standard ring sizes.

The best smart rings featured in our list are available in the following sizes:

SamsungFrom US 5 to US 13
SLEEPONOne size — 22 X 30 X 18 mm

Keep in mind that a properly fitting smart ring should feel comfortable and secure on your finger. The correct size is essential not only for comfort but also for accurate data collection, particularly if the ring includes sensors such as heart rate monitors.

Are smart rings compatible with all devices?

Even though compatibility depends on factors such as the operating system of your smartphone, the connectivity methods used by the smart ring, and the manufacturer's design choices, smart rings typically function with both iOS and Android smartphones through Bluetooth connectivity.

Considering this, it is advisable to do some research to make sure that the smart ring you are interested in functions seamlessly with your smartphone and aligns with your expectations regarding its features.

Best smart rings: conclusion

Smart rings are emerging as versatile self-tracking devices, seamlessly integrating technology into our daily lives. From continuous activity monitoring and heart rate tracking to sleep analysis and personalized fitness insights, these intelligent health rings may provide an in-depth view of our physical health and mental well-being.
