Battle of the Smart Rings
Two of the best smart rings you can buy right now are the Oura Ring 3 and the Prevention Circul+. Both pack big sensors into small form factors and promise to track various elements of your health and fitness.
We recently freed up some digital space for both rings to live on to get an idea of what these rings have to offer and if there’s one you should put your finger on the other.
Here’s a little breakdown of what to expect from the two rings and which one we’d choose to keep wearing.
Here’s our look at how the Oura Ring 3 (full review) compares to the Prevention Circul+ (full review).
Oura Ring 3 vs. Circul+: price
Before we get into all the hardware and software, how much are these smart rings going to cost you? Both rings are priced at $299, but with the Oura Ring 3 you’ll also need to pay a subscription to access your data. Circul+ uses a free app and cloud service to store your data.
This Oura Ring subscription service costs $5.99 per month, which is not a huge amount, but if you have already prepaid for the ring and are already supporting a whole host of other subscriptions monthly, it can start to add up.
So in the long run, Circul+ is cheaper.
Oura Ring 3 vs. Circul+: Design and comfort
Bottom line, one of these rings looks and fits like a normal ring and the other doesn’t.
The one that fits like a normal ring is the Oura. The sensors are well hidden under a sleek titanium design that comes in four different looks. It requires a sizing kit to ensure you get the best size option, but it’s sleek, stylish and comfortable to wear.
You have to make sure you have to wipe the sensors down from time to time and as you can probably see from our pictures the ring is not scratch proof if you don’t take it off as recommended for activities like lifting. weight.
You can wear it in the shower and swim with it thanks to its 100m water resistance rating.
The Circul+ is not a fully circular ring and comes in a single matte black look and comes in three sizes to accommodate most ring sizes. It’s not very pretty, nor is it suitable for wearing in water, but the IP65 water and dust resistance rating means it offers long-lasting protection.
The ring is however a little awkward to wear, but it is easy to put on and take off thanks to the spring mechanism built into the design.
Unlike the Oura, you notice that it’s always on and it’s not a wearable you can forget about even after a few days of wearing it. It’s a better fit for night wear, but again, the Oura is more comfortable for all day and night.
It’s a resounding win for Oura on design, comfort and looks like a ring you’d want to wear.
Oura Ring 3 vs Circul+: Health Tracking Features
When it comes to serious health monitoring features, there’s only one winner here – the Circul+. It has the sensors on board to track heart rate, SpO2, temperature and also supports the ability to take single-lead ECG readings and blood pressure readings.
The Oura Ring 3, on the other hand, doesn’t include serious health monitoring features in the way that an Apple Watch or Samsung Galaxy Watch does. So there is no ECG or blood pressure tracking. Nothing that is included that could be considered health features carries any kind of approved regulations to provide serious health information.
The Circul+ doesn’t have that either, but Bodimetrics, the health tech company behind it, says the ring has been medically tested and designed to work reliably on different skin tones.
The Oura Ring 3 can also track heart rate, heart rate variability, body temperature and will be able to monitor SpO2 levels when Oura activates the feature.
There is a distinct difference in approaches to how Oura and the Circul+ use these sensors and the information and data they can provide.
Oura Ring 3 App
Oura uses them to give you a better idea of what she calls preparation. It looks at things like heart rate, temperature, HRV, activity and sleep to tell you if you’re ready for a tiring day or if you should consider relaxing.
The Circul+ takes a much simpler approach. It will track real-time heart rate and SpO2 and can also continuously monitor these data points, but you have to manually enable continuous monitoring. With the Oura, you just put it on and let it follow automatically.
If you want to take an ECG and blood pressure reading on the spot, you will first need to calibrate the ring with data from a cuff-type blood pressure monitor before you can begin capturing readings.
What we found with the two rings first was that the data accuracy was very good. Both offered good real-time and resting heart rate data, and the Circul+ offered good SpO2 data, which the Oura currently lacks support for.
We found that while the ECG and Blood Pressure readings weren’t 100% accurate compared to another ECG and Blood Pressure device, they weren’t far off on most readings on the Traffic+.
All of this data captured by Circul+ is simply presented in the companion app with sets of graphs to show trends and dips and peaks in your data. You can also share this data with healthcare professionals if necessary. You don’t get any insight or actionable information to tell you if you’re ready for your day. It’s about presenting you with the raw data and letting you choose what to do with it.
This approach of simply presenting big health data may be what some people want. If you’re looking for a more guided approach that puts data into perspective and context, that’s where the Oura excels.
Oura Ring 3 vs Circul+: fitness and sleep tracking
These two rings can track elements of your fitness and will also monitor sleep time.
The Circul+ keeps things very basic on the fitness tracking front, logging step count and calories burned. Historical data isn’t presented in the app and there’s nothing like inactivity alerts or reminders to tell you to keep moving. You can also activate a continuous heart rate tracking mode when exercising, but the ring’s inconvenient design made it very difficult to wear while exercising.
The Oura Ring 3 offers a bit more on that front, but it’s by no means a perfect fitness tracker. It will count steps, track distance traveled, calories burned, offer inactivity alerts and display your daily movements in the companion app. It can also automatically recognize exercise and will optionally offer the ability to track heart rate during exercise. This data is all used to shape the overall readiness score you see at the start of your day. The ring is comfortable to wear for exercising and we’ve used it for running and swimming with no issues.
For sleep tracking, we’d say both perform quite well on that front. Again, with the Circul+, you’ll need to enable continuous monitoring mode to get the richest level of sleep tracking, which offers sleep duration, latency, sleep stage distribution, heart rate, SpO2 and temperature.
The Oura also offers rich sleep tracking, capturing sleep duration, sleep stages, sleep efficiency, heart rate and HRV for stress measurement.
We’d say the sleep tracking abilities of these two rings are pretty evenly matched. Basic data such as sleep duration and sleep time offered similar data. It was a similar story for heart rate. The Circul+ additionally gives you SpO2 and temperature data and graphs, so there’s more raw data to dig into.
The Oura and Circul+ are both solid sleep trackers, but when it comes to fitness tracking, the Oura comes out on top.
Oura Ring 3 vs. Circul+: Battery life
If you want the ring with the longest battery life and the best charging configuration, this is the Oura ring you want.
It promises 4-7 days of battery life and that is exactly what it is capable of delivering. The Circul+ in comparison can muster up to 16 hours of continuous monitoring, so it can’t last an entire day and as we found out you almost have to make a choice between continuous monitoring during the day or at night, which which isn’t exactly ideal.
When you need to charge, the Circul+ uses a small charging setup that can plug directly into a USB charging port, but the connection between the charging points and the ring makes it difficult most of the time to do so. sit properly to charge.
It’s a whole different story for the Oura Ring 3, where the cradle basically lets you toss the ring over it like a hoop toss and it will start charging with no problem.
Oura Ring 3 vs. Circul+: Verdict
So which of these smart rings should you choose? One promises to track your body and your recovery to help you make better decisions about what you do with your day. The other one is able to track and measure big health data which could help you monitor your health closely wherever you are.
If we had to choose a ring, it is the Oura Ring 3 that we would choose. Yes, it can’t track ECG or blood pressure like the Circul+, but as a whole there’s a lot more to like. The design is nicer and can be worn 24/7. The battery is better and there’s also some useful health information that feels useful and insightful despite not having any kind of regulatory approval.
The Circul+ offers much more raw health data and tracks it with great accuracy. The design and disappointing battery life make it a tough recommendation unless you really want something to track those rich health metrics primarily while sleeping.
