Amazfit Helio Ring vs. Oura Ring: First Impressions

It’s worth noting that while the Helio Ring is Amazfit’s first foray into smart rings, the company has been producing other smart devices in the health industry for years. The brand has more than a dozen smartwatches, indicating that it knows health tracking very well. That said, the Helio Ring obviously appears to be the product of Amazfit’s years of experience in the athletic health tracking field.

The Helio Ring’s exterior is made of a high-end and durable hypoallergenic titanium alloy, while the interior is made of transparent material to showcase its slew of sensors. The device measures 2.6mm thin and weighs less than 4 grams. The external design looks like the ring has perforations, and the matte gold color looks subdued enough to be worn with anything—whether you’re working out, at work, or just strolling in town.

The Helio Ring is water resistant up to 100 meters, allowing users to take it to the swimming pool. Currently, the Helio Ring is only available in sizes 10 through 12, and Amazfit hasn’t mentioned making the device available in smaller and larger sizes. Hopefully, the company will make them so that more consumers can use them.


Oura, on the other hand, has been making smart rings for over a decade now. The current model, the third-generation Oura Ring, is a product of many years of R&D, and its design and performance show that it is very good—to the point that most consumers consider it the best in its class.

The Oura Ring has two variations: the classic Heritage version and the slimmer Horizon version. Both rings offer the same features. The main difference between them is their look and price tags—the cheaper Heritage version uses a plateau design, while the more pricey Horizon has a sleek, uninterrupted look.

The Oura Ring’s exterior uses non-allergenic biocompatible titanium, while the interior is made of non-allergenic, non-metallic molding that’s transparent enough to show the device’s sensors. It measures 7.9mm wide, 2.55mm thick, and weighs 4-6 grams. It’s also waterproof, up to 100 meters, so users can wear it while swimming or snorkeling.



Both the Amazfit Helio Ring and Oura Ring feature the latest technologies, ensuring users get the best health tracking benefits. Here’s a quick look at what these smart rings have in store.

Amazfit Helio Ring

Amazfit hasn’t completely unveiled what kind of sensors and other tech is inside the Helio Ring, but based on the images and what the smart ring is supposed to do, it would have the following sensors at least:

  • A photoplethysmography (PPG) sensor
  • Red LED sensor
  • Green LED sensor
  • Accelerometer
  • An electrodermal activity sensor

These sensors allow the Helio Ring to be used for the following:

Fitness Tracking

Amazfit designed the Helio Ring as a fitness tracker worn on the fingers. The device measures VO2 Max, the maximum amount of oxygen consumption a person makes during exercise. This metric helps users determine their overall fitness, as do other biometrics the Helio Ring measures.

Performance Predictions

The Helio Ring can predict how users will perform in various running events. After running for 3km, the device will be able to obtain performance prediction data, which can then be used to estimate how the user will perform across different kinds of races: 3km race, two-mile run, three-mile run, 10km run, half marathons and full marathons. This will help users prepare for such events.


Recovery Recommendations

Aside from tracking and predicting user performance, the Helio Ring is also designed to help active users recover properly so they stay in tip-top shape. Users who subscribe to the Zepp Aura AI rest and wellness service will receive detailed weekly and monthly sleep reports with health assessments and insights, customized sleep sounds to help users get better rest, and more.

Stress Monitoring

The Helio Ring uses its electrodermal activity sensor to measure skin and sweat responses. This information can then be used to determine the user’s current level of mental stress. The device then helps users respond properly so they can improve their mental health faster.

Health and Sleep Tracking

Aside from the above-specialized uses, the Helio Ring can also be used to keep track of basic vitals for overall health monitoring. These include the user’s heart rate, heart rate variability (HRV), resting heart rate (RHR), blood oxygen, and respiration rate, among others. These will provide users with a better overall picture of their health.


Oura Ring

The Oura Ring, on the other hand, features the following sensors:

  • Infrared PPG sensors
  • Green LED sensor
  • Red LED sensor
  • Skin temperature sensors
  • Photodiodes
  • 3D Accelerometer

These sensors, along with the years of refining and improvement that Oura made to the Oura Ring, allow the smart health tracking wearable to be used for the following purposes:

Reliable Sleep Tracking

The Oura Ring is known for its accuracy in tracking its user’s sleep, as well as its ability to provide a detailed and actionable analysis. It will monitor specific information such as actual sleep duration, depth of sleep, restfulness levels, the length of time before the user actually falls asleep, and whether the user’s sleep is in sync with their circadian rhythm. The device will also keep track of the user’s respiration rate and blood oxygen during sleep and combine this information with the above to come up with the user’s Sleep Score.

Assessing Readiness

The Oura Ring tracks the user’s HRV, RHR, and body temperature and then combines these with the user’s Sleep Score to arrive at their Readiness Score. This will help users determine whether they have received enough rest and are ready to take on the day’s challenges.

Activity Monitoring

The Oura Ring is a reliable tool for monitoring movements and vitals, whether the user is exercising or not. The device keeps track of the user’s steps taken along with other biometrics such as respiration and SpO2 and combines all of this data to arrive at the user’s Activity Score. This score helps users determine if they are achieving a healthy balance of activity and rest on a daily basis. Oura will also help users know the amount of calories they burn per day.


Accurate Biometrics Monitoring

The Oura Ring has been tested and proven to monitor its users’ vitals accurately, the same accuracy as that of leading health trackers such as the Apple Watch. For example, the Oura Ring’s PPG sensor measures heart rate at 50 cycles per second to arrive at the most accurate readings. The device’s accelerometer is also able to detect even the faintest of movements. This makes it a reliable health tracker, especially for those who need very precise data.

Stress Management

Aside from tracking basic vitals such as heart rate, the Oura Ring will also learn its user’s biorhythms so that it can recognize and predict stress. The device will combine all of the data it measures, such as HRV and respiration rate, to provide users with insight into the factors that contribute to their stress. The Oura Ring will also help users develop stress resilience so they can prevent stress buildup and minimize its effects if ever it happens.

Menstrual Tracking

Aside from the above features, the Oura Ring can also help female users keep track of their monthly menstrual cycles. The device monitors its user’s body temperature to provide insight into how this influences monthly hormonal changes and helps women predict periodic cycles. This is particularly helpful for women who want to stay on top of their overall health condition.
