In the ever-evolving world of technology, innovation is the name of the game. As we strive to make our lives more convenient, we’ve seen the rise of smart devices that aim to streamline our daily routines. From smartphones to smartwatches, these devices have become an integral part of our lives. But what if I told you that the next big thing in smart technology is a lot smaller than you might think? Enter the RingConn smart ring. What follows is an updated version of my original review that I am posting having used the ring for about four months now.

The smart ring market has been relatively quiet as compared to other wearable tech, with few players making significant strides. The Oura Ring has been a notable exception, carving out a niche for itself with its focus on health and wellness tracking. However, the entry of RingConn and a few other options over the past year signals a shift in the landscape. The competition is heating up, and it’s clear that the smart ring market is on the cusp of a major transformation.

In this article I will delve into the features, benefits, and potential drawbacks of RingConn. I’ll explore how it works and what it can and can’t do. I’ll also compare it to its main competitors.

RingConn smart ring can typically be purchased for $279 on the manufacturer’s website. For $10 off, at checkout use discount code: BFD50EC113.

RingConn smart ring review: Design, hardware

Look & feel

As soon as I unboxed my RingConn smart ring, I was struck by its straightforward, functional design. The premium presentation box it arrived in underscored the meticulous care and precision that has gone into crafting this device. Available in three metal colors – gold, silver, and black – the RingConn doesn’t try to be overly stylish; instead, it focuses on serving its purpose as efficiently as possible.

The outer-square, inner-circle design gives the ring an exclusive yet minimalistic look, while also ensuring maximum comfort. Weighing only between 3 and 5 grams depending on the size, you hardly notice you’re wearing it. It’s discreet, comfortable, and looks nice on the finger, making it a perfect everyday companion. On your hand, it looks like a modern piece of jewellery.

Before the ring itself is shipped, you receive a complimentary sizing kit, allowing you to determine the appropriate fit from nine different options (ring sizes 6-14). This means when purchasing, your only real decision is the colour. A perfectly fitting ring not only ensures better comfort but also leads to more accurate tracking.

The good thing is, the ring can be worn on any finger of your right or left hand. So if the size is slightly off, you can opt to wear it on a different finger or hand. It takes a bit of the pressure off deciding on a perfect fit.

I mostly wore my ring (size 11) on my index finger, which was a comfortably snug fit. It’s worth mentioning, the ring is not omnidirectional. Ideally, the green and red lights need to be on the palm side of your hand. But I’ve noticed that even the sensors are not the right way around, the ring still works pretty well.

Having said that, I wish there was some sort of mark on the device, which would let you know with a glance whether the ring is positioned correctly. The company says there’s a slight concave at the top that can be used to position the top and bottom. They have adopted a tactile positioning method instead of a visual one.

It is advisable to wear the ring on the hand that is not dominant. This minimizemovements that could potentially lead to an exaggerated step count. The placement of the ring on the finger presents certain challenges in tracking some metrics, with step count being one of them. This is an inherent limitation because there is greater flexibility of hand movements as compared to the wrist movements when wearing a smartwatch.

As far as durability of the ring is concerned, the device is PVD coated and I’ve noticed some users on social media have complained about scratches. I opted for the grey edition, and four months in I’ve had no such problems. Perhaps the grey version is less susceptible to such damage as compared to the black version. Also, I have been extra careful not to mar its surface. For those that would like some extra protection, the company sells an optional add-on in the form of ring protectors.

This device is designed for round-the-clock wear. It comes with a great IP68/5ATM rating, ensuring that it is impervious to dust and can withstand water up to a depth of 50m. Initially, I was cautious while washing my hands, but eventually I became fully convinced of the ring’s water-resistant capabilities. I have taken numerous showers, done the dishes repeatedly, and engaged in several swimming sessions while wearing the ring, and have encountered no issues whatsoever.

Under the Hood

Inside the RingConn smart ring lies a sophisticated set of hardware components. The device is armed with infrared, red, and green sensors, in addition to an accelerometer, which together drive its tracking features. Connectivity is facilitated through BLE 5.2, with no Wi-Fi support. Additionally, the ring incorporates EMF-Safe technology and features an airplane mode for those moments when it’s necessary to go offline.

In terms of storage, the RingConn smart ring is endowed with a memory capacity capable of retaining up to 7 days of data. This enables extensive monitoring and assessment without the hassle of frequent data transfers. Having said that, you probably will want to sync daily as this is the only way to view your metrics.

The ring establishes a connection exclusively via Bluetooth to the smartphone app, and it seems to disconnect from the phone when the RingConn app is not in active use – this is probably to conserve battery life. Upon launching the app, it takes a few moments to establish a connection and initiate data synchronization. However, once connected, the connection remains stable. VPN can mess with this connection. So that’s something to be aware of for those that have it.

As for the presence of a vibration motor, the ring does not have one which is consistent with the majority of such devices. It is difficult to fit that sort of tech into something the size of a ring.

A week of battery life

Moving on to the all-important battery life. This is a problem with some of the options on the market.

I’m happy to report RingConn boasts a battery life of up to 7 days when fully charged, a claim that I found to be accurate in practice. The ring recharges fully in about an hour and a half. While some users have reported a decrease in battery performance over several months, the company has proactively addressed these concerns by providing replacement units. Personally, I’ve observed a minor decline in battery longevity, though it hasn’t been significant enough to warrant contacting customer support.

The charging case, which is conveniently portable and specifically tailored to the size of your ring, offers the ability to recharge the device on the go. Whenever I take a shower, I reverted to placing the ring in the case for a quick partial charge. This way, I avoided the situation of the ring reaching a nearly depleted state.

What is lacking at the moment are notifications if the ring battery is running low. The smartphone app has the ability to send notifications, but only if it is open. The company says it is working on push notifications.

Technical specs: RingConn vs Oura Ring

Now, let’s delve into how RingConn’s technical specifications stack up against the market leader – the Oura Ring. As illustrated in the table below, RingConn is on par with its more renowned but pricier rival. Both are crafted from pretty much the same materials, and they share similar dimensions, weight, and sensors.

Additionally, both rings advertise the same battery life. However, it’s worth noting that there are numerous online reports suggesting that the Oura Ring doesn’t quite live up to its battery life claims. So these should be taken with caution. As a bonus, RingConn comes with a portable charging case, which isn’t an option with the Oura Ring. The one area where the Oura Ring has an edge as far as hardware is in its superior water-resistance.

Of course, there are differences in terms of functionality as well. The extras RingConn brings over Oura Ring are stress metrics and 24/7 tracking of heart rate variability and blood oxygen. Oura only tracks these two metrics overnight.

In terms of cost, the Oura Ring is roughly $50 more expensive than RingConn, and there’s also a $6 monthly subscription fee on top of that. Which adds up over the long term.

On the other hand, RingConn does not require a monthly subscription, and the company has stated that they have no intentions of introducing such a fee. Unfortunately, the trend of implementing monthly subscriptions among wearable brands seems to be gaining traction. Here’s hoping that RingConn remains committed to its stance.

Another competitor comes in the form of the Ultrahuman Ring Air. You can check out our detailed article comparing RingConn to this device.

RingConn smart ring review: Features

As a first-time smart ring user, I was eager to test out RingConn. It promised a new form factor, away from my usual array of smart watches and bands. I’ve had a multitude of these over the years!

The smart ring has its origins in a crowdfunding campaign. Some $1,245,500 was raised via Indiegogo, which has been funneled into the RingConn’s development. This makes it one of the most funded smart ring crowdfunding campaigns ever.

RingConn review

As someone who tests wearable tech products for a living, it became quickly clear to me that RingConn is not just a startup company shipping any old thing. They are delivering working rings and are committed to refining and improving them every day.

This is their first generation ring, and they’ve proven to be one of the most responsive companies I’ve come across. They offer software and firmware updates and have multiple channels for addressing and resolving user-reported issues. The one I would suggest visiting is their very active Facebook group. Updates are posted on a daily basis.

Using the ring

The initial setup process is pretty much hassle-free. First, download the smartphone app, register your details, and then follow the instructions for pairing the ring. Don’t forget to charge the ring fully before starting the setup.

Beyond that, the device doesn’t have any noteworthy settings or calibrations. It’s as simple as slipping it on and getting on with your day.

The companion smartphone app is well-crafted. There’s an ‘Insights’ screen which presents a synopsis of your activities. By tapping on any metric or swiping, you can access a wealth of detailed information on Sleep, Activity, and Stress. As the name suggests, the ‘Trends’ section offers a glimpse into your long-term progress. You have the option to organize the data by week, month, or year. A recent edition comes in the form of a daily timeline.

You also have the option in the app to connect to Apple Health and Google Fit. It can be found in the settings section.

Like its rivals, the ring’s functionalities are primarily focused on recovery statistics, encompassing heart rate and heart rate variability. There is in-depth analysis of your sleep patterns, including aspects such as nap duration, total sleep time, durations of deep, REM, and light sleep, as well as sleep efficiency. The device also keeps track of SpO2 and stress levels throughout the day, attributing specific scores for early morning, morning, afternoon, and evening.

It is worth mentioning, accompanying a few of these metrics is a “score” which lets you know at a glance how you are doing for a particular day. In addition to a wealth of charts for pretty much every single data point.

You might even see this as an overflow of information. At times I did feel overwhelmed. But I would rather have too much data than too little data! Regardless, I can’t help but feel the company could make the app more user friendly by getting rid of some of the superfluous charts.

Additionally, there’s a skin temperature monitoring feature. This operates during the night, contrasting your stats against a baseline value accumulated over an extended period. The reason it doesn’t operate during the day is because there are lots of factors affecting the skin temperature in daylight, which would lead to inaccurate results.

In the coming months, new features will be added. This includes data report export, Training Mode, Apnea syndrome monitoring, Sleep Coaching, and more. So more things to look forward to.

It is worth mentioning, the company asserts that they “strictly follow industry standards to protect user data.” That’s important in this day and age. Additionally, they conduct regular user privacy training and perform routine testing of servers and systems.

Accuracy of activity metrics

In terms of physical activity, the device provides information on step count, calories burned, as well as activity and walking distance. So its fairly standard stuff.

In assessing accuracy, I found that heart rate measurement during exercise to be a weak point. The readings are not as precise as those from the Garmin Forerunner 955 that I wore on my wrist. The heart rate figures were consistently lower on the RingConn compared to the Garmin. But capturing heart rate during high intensity exercise seems to be a problem with all smart rings.

It seems that RingConn is poised to address this issue, as they have slated a firmware update aimed specifically at enhancing the algorithm for activity metrics. I surmise that for fitness tracking, the ring may need to capture heart rate data at more frequent intervals.

As for step counting, I found it to be quite reliable. There was only a marginal deviation when I looked at my Garmin data. RingConn has stated that their step counting algorithm boasts approximately 96% accuracy compared to manual step counting, which aligns well with my personal experience.

Accuracy of recovery stats

What truly stood out to me was the precision of the recovery statistics. RingConn excels remarkably in this department, which is quite impressive, especially considering that this is a first-generation device.

RingConn review

Besides the Garmin, I also sported a Whoop 4.0 on my bicep, so I made a point to meticulously compare the recovery statistics among the three devices over the course of a couple of weeks.

Below is a table that illustrates the correlation between Garmin/Whoop, Garmin/RingConn, and RingConn/Whoop with respect to nightly resting heart rate and heart rate variability. Interestingly, as depicted in the table, RingConn exhibits a significantly closer correlation with Whoop compared to Garmin.

This was particularly the case with resting heart rate values which showed a 98% correlation with Whoop. At 86%, also impressive was the correlation in terms of heart rate variability.

As far as sleep tracking, the correlation between the three devices was similar, at around 85%. However it is worth noting that RingConn and Whoop can track naps, while the Garmin doesn’t have this ability. They are not perfect but do pick up some naps. You have the option to manually enter others. The sleep figures in the table below only show nightly values and do not include this type of data.

Recovery data correlation between RingConn, Whoop and Garmin Forerunner 955 – 2 week period

During this two-week assessment, the resting heart rate data was notably comparable among the three devices, with RingConn landing squarely in the middle at 52 beats per minute. A similar trend was observed for sleep duration, where RingConn had an approximate average difference of 13 minutes in nightly values compared to the other two devices – an impressive feat.

On the other hand, a more significant disparity was noted in the nightly Heart Rate Variability (HRV) data, with RingConn consistently recording higher values compared to both Whoop and Garmin. This discrepancy is likely attributable to variations in the methodologies employed to calculate this metric. Importantly, this difference should not be a cause for concern as the correlation in the trends of HRV – the rises and falls – was remarkably close. It is these relative changes in HRV that are considered more meaningful in analyzing the data.

If one takes Whoop 4.0 as a model of accuracy due to its high sampling rate, this level of concordance with RingConn was something I didn’t expect. Garmin and Whoop show a much larger discrepancy in their figures.

RingConn smart ring review: The bottom line

RingConn has positioned itself as a promising entrant in the smart ring space particularly for those who are keen on tracking their recovery statistics. Its sleek design ensures that it doesn’t obstruct your daily activities and its hassle-free setup makes it a user-friendly option for a wide range of consumers.

The accompanying smartphone app, while brimming with information, might be a bit overwhelming for some. But it’s commendable for the detailed insights it offers, while integration with platforms like Apple Health and Google Fit is an added bonus.

In terms of accuracy, RingConn truly shines is in its recovery statistics; with a high degree of correlation in resting heart rate, heart rate variability and sleep tracking as compared to well-established rivals such as Whoop. While the heart rate measurement during exercise needs to be improved, the company’s proactive approach in rolling out updates and engaging with the community is a good sign for future refinements.

All things considered I am impressed. The features, hardware, and performance of RingConn present a viable alternative to its primary competitor, the Oura Ring. Plus you get all this at a more accessible price point and no monthly subscription fees.

As the company continues to update their product, I look forward to seeing how RingConn evolves. If you’re in the market for a less obtrusive alternative to wrist wearables and have a keen interest in recovery statistics, the RingConn is a solid choice.

RingConn smart ring can be purchased for $279 on the manufacturer’s website. For $10 off, at checkout use discount code: BFD50EC113.

Update (15/12/2023): RingConn smartphone app version is out — it introduces a Wellness Balance score along with temperature tracking, respiratory tracking and other features. Read more…

10 thoughts on “RingConn smart ring review: Four months later and still impressed

  • Any link or the picture of HRV status able to show RingConn having 24/7 tracking of heart rate variability and blood oxygen because other products for the consumers mostly only track these two metrics overnight? Or, is it a mistake to say so in this article?

  • Is this safe to wear with a pacemaker?

    • Best to check with the manufacturer.

    • yes, it’s safe.

  • The article says that “the Oura Ring is only $50 more expensive than Ringconn. This is incorrect. The top of the line oura ring (Rose Gold) which has a lot less features than Ringconn, is more than TWICE the price of a Ringconn at hovering around $490 Vs $245 for the RingConn.
    I just recieved my first Ringconn and as a former Oura Ring user, I have to admit how pleasantly surprised I am with the quality of this ring. Matches or beats Oura every step of the way, straight from the unboxing with overall app functionality that is far superior to the Oura Ring.

    • And that’s not taking into account the monthly subscription which RingConn doesn’t have. I was pleasantly surprised as well at the quality of data. Much more competition now in the smart ring space.

  • Can you clarify the Apple Health data flow. Can I record a workout on a Garmin, sync it with Apple Health, and the data get to the RingConn app where it’s factored into the various scores? If not, any idea if it’s planned?

    • It works in one direction – RingConn to Apple Health. Workouts are not synced from Apple Health. Not sure that is planned. It wouldn’t make sense as RingConn tracks your heart rate during workouts – even though it won’t produce detailed Garmin-type metrics.

      • Thanks so much. Oura apparently does get data from others and factors it into the overall scores. As someone who works out 5 days a week (triathlon), this is important, so unfortunately, RingConn may not be optimal.
        I appreciate the detailed information you provide. Keep up the good work.
