Customer Ratings & Reviews

Great ring! Love the technology and the data this ring gives!!

The Oura Ring Gen 4 is truly a remarkable feat of engineering. It looks like a normal ring, no one has been able to tell that I’m wearing a smart ring. But anybody could make one with crummy sensors inside, a bad app, a bad finish, etc. Oura is different though. The accuracy is incredible, I’m finding little difference between actual medical measuring devices and the ring's data. If you are wanting to be more in touch with your body and health, this is the device to get. The app is thorough and extensive. In fact, I’m still finding data points it tracks and reading about what each means. The explanations of measurements and how to adjust your life accordingly are very helpful and in-depth. If you don’t know how certain measurements work, you will learn through this app. The fact that some of the more complicated measurements can take up to a month or two to establish a baseline feels trustworthy. They aren’t going to start giving you bunk data without establishing a trustworthy baseline. I think what held me back from previous Oura rings was that they highly suggested you wear it on your pointer finger. This time around with the Gen 4, you can put it on any finger! So I used it to replace my wedding ring and it’s like nothing every changed. Other than taking it off for a couple hours once a week to charge it. But it charges so fast and lasts so long that it really is a non-invasive piece of tech in your life. Overall, I absolutely LOVE this ring. My quibbles are small and few. My fingers have boney knuckles which usually requires a slightly larger ring, usually a half size, but unfortunately there are no half sizes. The ring is a little snug, but that is ideal for best measurement. Android also says that the app is a resource hog, but I haven’t noticed a big battery difference. I think the biggest problem is having to pay a subscription, but this is a high end device so I guess that should be expected. I highly recommend getting one, and when you do, make sure to use the sizing kit first to make sure you order the right size! Pros: Can wear on any finger now! 6-7 day battery life Very accurate measurements Explanations of the measurements Completely normal looking ring now Rose gold is a perfect color Cons: Can be hard to understand what to do with this data No half sizes, which is a struggle for my knobby fingers Android says the app is resource hog Would love haptics for notifications so I could ditch my smart watch Subscription required for a lot of features

The Oura Ring 4 is the fourth generation of this compact health and activity data monitoring product. It supersedes the Oura Ring 3 which has been available since 2015. The new Ring 4 is an improved, slimmer version with more sizes for a better fit, better sensors and longer battery life. Oura Health was founded in 2013 and is based in Oula, Finland. Oura Health has become the foremost developer of wearable personal health data monitoring devices. It created its first Oura Ring in 2015 which has evolved to a new generation (Ring 2 in 2018, Ring 3 in 2021 and now Ring 4) every three years. The Oura Ring collects a variety of biometric readings more frequently than competitive devices and integrates that data in a well-designed app which provides advice on maximizing health and fitness. More than 2.5 million Oura Rings have been sold to date. Here are the key features of the new Oura Ring 4: • Oura Health Ring Generation 4 (Model JZ90-54220-12) • All titanium ring construction, six surface finishes: Gold, Rose Gold, Silver, Brushed Silver, Black, Stealth (dark grey) • Available in 12 sizes (#4 - #15), free (after credit) sizing kit available • Oura App provides extensive data analysis and advice to optimize health and sleep • Sensors integrate with app to monitor: Sleep quality, sleep apnea, heart rate, heart rate variability (HVR), temperature, blood oxygen, cardio capacity, cardiovascular age, stress, activity, resilience, menstrual cycle, body clock • Recessed Sensors: Red/IFR LED (Blood oxygen), Green/IFR PPG (Heart rate, variability, respiration), Digital temperature (Body temperature, variability), Accelerometer (Movement, activity) – more than twenty biometrics continually monitored • Smart sensing algorithm adapts to skin structure, tone and activity, optimizes battery life • 18 signal pathways improve accuracy and continuous reading capability of sensors • Memory capacity: One week of activity and sensor readings • Automatic firmware update via Oura App • Bluetooth Low Energy connectivity, 30+ foot range, EMF-safe, airplane mode available • Lithium polymer battery 15mAH (#6)-22mAH (#13) provides 8 day life, full recharge in 90 minutes, daily recharge in 15-20 minutes • Waterproof to 328 foot depth • Operating temperature range: 14 degree F – 129 degree F • 5 VDC wireless charging dock and 38” USB-C to USB-C recharge cable included • Dimensions: 7.9 mm Width, 2.9 mm Thickness, 20 mm (#4) – 29 mm (#15) Diameter • Weight: 0.2 ounce (ring), 2.3 ounces with charger and cable • Made in Estonia • One year warranty on parts and labor Setup: When you open the Oura Ring 4 box you will find a QR code to download the Oura app. This is the essential element to analyze and manage the data generated by the ring. To set this up, just enter your email address. Then you are given a link to Oura website. At the Oura website, create a unique password and you are given a code which allows you to register the ring, connect the ring via Bluetooth and update the firmware. Then enter your personal details (country, age, weight, height, sex) to enable the Oura app to properly interpret the biometric data generated from the ring. If you are an iPhone owner, the Oura app will connect to Apple Health to integrate and access the data stored there. A brief questionnaire will help the Oura app to focus on your health and fitness goals. While you are doing the setup, unpack the Oura Ring and set up the charger. (By the way, the charger is sized to match the ring size, so it is not interchangeable with rings of other sizes.) Place the ring on the charger to top off its battery. When fully charged, the white charger LED changes to green. If a ring’s battery is fully depleted it will take up to two hours to recharge. The battery life is substantial and should last eight days without recharging. I found that the battery drain is about 15% per day. By placing the ring on the charger each day while I was in the shower (15-20 minutes) the battery was restored to full power. Once the Oura Ring is fully charged, put it on your finger and rotate the ring so that the indentation is on the palm side of your finger. The ring should fit snugly and there should be no significant gaps between the ring and your skin. You may find that you can also wear the ring on other fingers. I found that sensitivity was very good and the ring generated accurate data even when on a finger slightly different in size than the finger for which you selected the Oura Ring size. The Oura Ring 4 has several advantages over its predecessor – it is thinner, lighter and the sensors are all recessed so it is more comfortable to wear. Plus it has more sizes so it will provide a better fit. It is also more durable since it is all titanium with a decorative surface finish. If you engage in activities which may scratch that finish (e.g., working out with weights) you can buy inexpensive silicone covers for the ring to protect it. Use: If you own an Apple Watch or other fitness watch you are conditioned to glance at the watch to read various data while exercising (heart rate, pace, calories burned, distance, steps, etc.) The Oura Ring has no display, so you must access the Oura app to see the data being generated. The only display is a red or green glow which indicate when your biometric measures are below (red) or above (green) normal. The Bluetooth Low Energy wireless connectivity provided a solid signal up to 50 feet from my phone and was very stable in all conditions. However, even if you do not have your phone with you, the Oura Ring will store data internally for up to eight days of use. When you bring the phone back into proximity it will synchronize and download all stored data. The key to effective use of the Oura Ring 4 is to allow it to build a solid baseline of your biometric data. This takes about two to three weeks of continuous use. During this learning period the Oura app becomes better and better at assessing your health condition. It uses this assessment to give you advice on the activity each day which will optimize your health, fitness and sleep. The app is also excellent at giving you a quick summary of your current condition (Readiness, Sleep, Activity, Heart Rate, Stress) – much better than the Apple Health app. Is it accurate? Both independent and Oura-sponsored research have confirmed that the Oura sensors provide data as accurately as specialized medical equipment. The Oura app works well to integrate and track all of this data so you trust its conclusions. Since I have worn an Apple Watch for five years and use it to track my exercise activities I was curious if the Oura Ring 4 would be a substitute, supplement or irrelevant for Apple Watch users. First, it is obviously not a substitute since it cannot offer any data readout by glancing at it during a run or bike ride. But does it offer enough additional value to justify it as a supplementary device? The answer depends upon your willingness to follow its AI-inspired daily advice and your general health condition. There are three categories of users who will certainly benefit. First, the truly committed health enthusiasts who seek every bit of data on their condition. Next, those with specific health issues who need to monitor those conditions. Finally, those who want to continuously monitor their health but don’t want to wear an Apple Watch when sleeping or in social settings where wearing the Watch is inappropriate (e.g., a formal event.) However, in all cases, keep in mind that the Oura Ring 4 is part of a system which includes a near-mandatory subscription to Oura Membership ($6/month or $70/year) in order to access all of the analysis and advice available in the app. I wish that Oura would simply offer a lifetime membership as part of the purchase price. Bottom line? The Oura Ring 4 is a marvel of compact, effective technology. The Oura app is superb and nearly all users will gain great utility from its data analysis. I love the product but have some qualms about the need to maintain membership for $70/year so I am giving the Oura Ring 4 just four stars. I recommend it, but only to those who recognize that ongoing cash commitment. But aside from that if you purchase the Oura Ring 4 I think you will be delighted with its subtle elegance in appearance which hides its awesome technologic power.

I like the raadings i have managed tou dersts d how to get. Very techie little thing.

Love the ring concept just don’t like the brushed look. It looks cheap.

It’s a cool product but you have to pay a yearly fee of $70 to see most of the things you bought it for. Other than that I like it.

My ring came with battery issues. I had to reach out to Oura directly and they will send me a replacement but so far good

The Oura 4 is hands down the best fitness ring available. It looks great (I got the stealth color) and so far I've found it to be super durable. I'm amazed at the technology Oura has been able to pack into such a tiny package. The ring is hardly bigger than the average wedding band, yet it senses heart rate and heart rate variability, blood oxygen levels, temperature, and it has an accelerometer to track movement, including steps and movement while you sleep. And somehow they figured out how to pack into it a battery the lasts for 8 days. Speaking of sleep, sleep tracking is my favorite feature. I don't sleep well, so knowing what's going on with my body is important for developing a sleep plan that optimizes efficiency. I've used watches to track my sleep in the past, and always suspected they weren't very accurate. The watch would indicate I was getting 8 hours of sleep, but somehow I still felt tired. I compared my watch with the Oura Ring 4 and while the watch was saying 8 hours of sleep, the Oura 4 was saying 6.5 hours, showing me an accurate picture of when I actually got to sleep, and how long I stayed there, as well as giving me ideas on what I can do to sleep better, with reminders to take specified steps. And most importantly for me, it showed me when my O2 levels dropped off. I have mild sleep apnea, so keeping an eye on that is important for heart health. I honestly can't say enough positives about the Oura 4. The ring is gorgeous and functional. The app is really good, as well, breaking down all data for you and putting the information in an easy-to-read format. I'm pretty sure I haven't even touched the surface of what can be learned from the app, but I'm getting there. I highly recommend the Oura 4, whether you're a fitness guru, or you just want to understand your body better.

I’ve always worn some kind of smart watch to monitor my fitness. Mostly Fitbits. The biggest drawbacks to a smart watch is battery life - frequent charging - and not tracking my health when I wear an actual watch (which I like doing when going out or attending a formal event). There’s also a question of what to do with all the data your watch gathers? What really separates the Oura ring from other health trackers I’ve used is the helpful advice it gathers. In some ways it takes the data and gives recommendations (vs. just telling you how long you slept or how many steps you made). But it requires some work. While it does a great job of automatically tracking activities/sleep and HR, to really take advantage you have to go into the app and tell it what you’ve done. That can help establish patterns, matching what activities you’ve done one night that might mean you’re going to sleep worse. IN THE BOX AND SETUP In the box you’ll get your ring, charging base and charging cable. Setup is dead simple. You pop the ring on the charger and download the app. I was up and running in no time. Of course there was a firmware update, but it didn’t take long. It takes a week or so to track your vitals to get a baseline. But it’s awesome being able to wear a device that doesn’t have a screen and has long battery life, so you literally just wear it and forget it. DESIGN I’ve been super impressed with the design and durability of the ring. I opted to wear it in lieu of my wedding band. My wedding band has lots of signs of wear and tear on it (mini scratches that could be polished out). I’ve worn the Oura full time doing everything I would normally do, other than lifting weights. It is recommended that you don’t wear it while lifting weights. But I’ve been seriously impressed that it’s shown no signs of scratching. It’s a small sample size, but still, I would have expected some scratch by now. Point being, it’s a well designed, and great looking ring. ACCURACY It’s difficult for me to say how accurate it is, the best I can do is compare my vitals between my Oura ring and my Pixel Watch. It’s incredible how similar they are. It’s amazing all the sensors and battery fit in such a small device. In any event, I can at least say that the Oura ring’s accuracy is just as good if not better than my Google Pixel (and you’ll have to assume the Pixel Watch is accurate). USE Like I said, you simply wear this device. There’s obviously no screen, no distractions, no extra device bugging you. I love the simplicity when I want to track my activities without getting notifications from a watch or phone. But you can’t talk about the use without talking about the app itself. The app, to me, was a little overwhelming at first. There’s a lot there. Like most apps, however, you spend a little time in it, and it will make sense. I wouldn’t say it’s the most intuitive app I’ve ever used, but the layout makes sense. The Oura ring can automatically track activities. So if you go for a run, it knows you went for a run and will track your stats. Same goes for cycling. It’s a bit hit and miss on indoor cycling in terms of automatically recognizing it. But if you were to open up the app, it will typically ask you to confirm or edit activities. Sometimes I’ll know I went for a walk, sometimes it will detect an activity that I didn’t remember as an actual activity. You’re able to edit activities or add them. The idea is that it helps keep track of your activity level, offering advice as to things you can do to improve your activity level. Sleeping, it measures your total sleep, efficiency and REM sleep. It gives you all this data in a nice chart - similar to other sleep trackers. But it automatically keeps track of when you go to bed and wake up, and then will be proactive in sending notifications to your phone to let you know when you should start winding down to make sure you get enough rest. Again, this is all automatic. The non-automatic part, is that you can go in and for each day select 2 dozen or so different options (like late workout, caffeine late in the day, etc.). If you stay diligent about this, the app will recognize patterns to help coach you on what you should or shouldn’t do to get a better night’s sleep. What I like the most is recognizing stressors. It will flag when your vitals spike and identify stressors throughout the day. I found these to be pretty spot on, when I braked hard in my car and my adrenaline spiked, it recognized it as a spike. It measures all this in 15 minute intervals. In short, think of Oura as a comprehensive device that includes the app and the ring, that offers coaching to better help you meet your goals, whether it’s to get better sleep, workout more, or lower your stress. But the app does require a subscription to take full advantage of all these features. The only other downside I see is getting locked into the one size ring (obviously it’s not adjustable like a watch). So you’re kind of stuck with using whatever finger you sized it for. CONCLUSION In some ways, the Oura is similar to most fitness trackers. I get similar data between my Pixel watch and the Oura. But the big difference is the app itself, which offers great advice (and it reminds you to give yourself grace). It unfortunately requires a subscription to get the most features, but the price is in range with what you’d expect (but something to consider for the price conscious). The ring itself is pricey, but you’re getting a well designed, durable, and sharp looking ring. While the price is subjective as to what you can afford, as a value proposition, taking into account everything it offers, it’s well worth it. No more do you have to find time to charge a device every single day to track your sleep, you need only charge this once a week and it charges fast. The downside of no screen on your tracker is that all the notifications come through your phone (i minimize my app notifications as best I can) but I’ve yet to find a wasted or otherwise notification that bothered me from Oura. I’m extremely pleased.

definitely ends up getting scratched since you are wearing it 24/7, you have to pay for the app and there’s not much that it tells you but if your sleeping schedule

This Oura ring is something I haven looking to try for quite some time since now of my good friends attributed better health results to wearing a ring. I already own and wear a fit bit watch, so I was interested in learning whether there was much overlap in their functions and features. and whether these was any benefit to wearing both or advantage to one over the other. My conclusion is that they are different enough to justify wearing both. Here is what I like about the Oura ring: - It tracks sleep and scores it. I had had difficulty getting that other device to produce sleep information. The Oura makes it easy to find the score on a dashboard across the top of your home page on the app, then tells you what goes into the score, plus it provides insights into how to manage the score. - It tracks movement. Oura gives you the option to track calorie burn as they measure it, or steps. I started with calorie burn and found I achieved my goal too early in the day, so I switched to steps to push myself to do more throughout the day. - It tracks heart rate. - It measures what it calls Stress. Oura shows you when you are stressed, which I found to be when I am moving a lot. I don't think there is anything the sensors can track which measures mental stress, especially since it cannot track blood pressure, so I found this feature less useful so far. - It has excellent battery life. The manufacturer claims up to 8 days and I found that to be accurate. - It looks good. The styling is clean and basic, and the workmanship is excellent. It is made of pure titanium, and I have not had any allergic reaction to it. I expect it to last a long time. - It is comfortable. I wear it every day and sometimes forget I have it on. - It provides what it calls a "Readiness" score. I am still larding to use this feature which combines various measurements to tell you if you are "refreshed" and ready to take on the day. It supposedly also can tell you when you are getting sick, but I did not experience this. There are additional measures for women's health which I, as a man, did not use. Where I wish it were better: - Oura claims connectivity with 40+ apps. I can see 10 on my Oura app. Of those, I only recognize Noom and Headspace, neither of which I use. I wish it would connect to more stuff I already have or use. - It cannot track blood pressure. I get it that there are physical limitations to what a ring can do and that it will never duplicate an arm cuff, but perhaps a cuff could be developed as an add-on which would feed into the Oura app, either theirs or maybe someone like Omron. - Of course, it is a subscription "recurring revenue" business model, so I hope they keep adding value and features or else I may move to something better.

Does the job but very uncomfortable to wear a ring this large on a different finger than you normally wear a ring.

I didn't know what to expect initially as this is my first smart ring. The Oura ring 4 is on the larger side compared to regular rings and other competitors. I compare it to a class ring although it's lighter and feels a bit like plastic. Although it is made of Titanium, it is very lightweight and doesn’t feel like it is metal. The ring does take some time to get used to (took close to two days for me personally) as the band is wider. Setting up the ring after unboxing it was very easy; I installed the Oura app on my phone and walked through each of the steps on the app. It was as simple as sliding the ring onto its dock (small square with the outline of the ring), creating an Oura account, answering a few questions about your health including goals and about your sleep, and accepting a few permissions from the app to track your health data. Once this is complete, you are able to start wearing the ring and it will start tracking your movement, heartbeat, and more. One thing I'd like to point out is to begin tracking your exercises and activities automatically, you will need to accept all of the Oura app's permissions. Initially I believed I did but I went into my activity history for the day and noticed there were additional permissions for the app that I missed. After enabling them, it began to track my physical activity pretty well (more details below). The ring tracks 5 main categories of your health: readiness, sleep, activity, heart rate, and stress. Readiness details your energy for the day based on sleep data and heart rate variability and gives recommendations on how to go about your day. Sleep, if the ring is worn while you sleep, keeps track and shows your sleeping patterns and heartbeat while you sleep. Activity presents your activities throughout the day as well as estimated calories burnt and number of steps taken throughout the day. Heart rate displays your heart rate throughout the day in 30 minute increments and is further segmented based on multiple categories such as your average heart rate and it's range while asleep and during activities. Stress is calculated and not available until after wearing your ring for a week but gives recommendations based on a calculated amount of time it measured you were stressed. It is calculated based on your heart rate variability, heart rate, motion, and body temperature. All categories are shown with a score and are updated throughout the day based on activities. Each of these categories is tracked through the multiple sensors the ring has including red, green, and infrared LEDs as well as a digital temperature sensor and accelerometer. The different sensors measure blood and oxygen levels, heart rate and heart rate variability, respiration rate, temperature, movement, and activity. While listing some of the sensors, I would also like to point out that the Oura 4 can be used in water up to 100 meters and in saunas. It is not recommended to use when diving though. Since I was mainly interested in using this ring for fitness reasons, there were a couple of things I wanted to point out about it. One, I definitely prefer using it over my smartwatch when exercising and weight lifting. It was more comfortable for me personally and was easier to wear throughout the day and when sleeping (to track my sleeping schedule). Two, I liked how you are able to track exercises. You can specify the specific exercises you completed throughout the day and have a record of the time it took you to complete the exercise (start and stop times). Oura has over 80 different activities listed that you can choose from and help calculate how many calories are burned based on the time and intensity of the exercise. For a much shorter list of exercises, including walking, running, and cycling, you are able to record a much more precise exercise and can set a timer. Wearing the ring made me realize how often I was up and moving throughout the day and helped encourage better health lifestyle choices like walking and exercising regularly. This was mainly my personal choice but through the app and it tracking various health data, it helped put into perspective some of my fitness goals and changes I needed to make to reach them. I also wanted to point out that having the ring as a wearable does not replace having a smartwatch (since its main use is to check the time. I personally found it much more comfortable to wear for extended periods of time as compared to a smartwatch although it does not fill in some of the features especially quickly checking notifications and checking the time and date quickly. There are more features that I personally don't need vand haven't used including insights specifically for women like period cycles and probable fertility windows but find helpful for my other half if she were to begin using it. Lastly, as for it's battery life, I wore it for close to 7 days consecutively, only taking it off each day to shower, and it survived with about 2% of battery left. It included me wearing it during exercises and while asleep. Some of the things I would love to see in Oura’s next generation ring would be a small vibration sensor embedded within the ring to notify you of notifications (specifically calls and messages). Another thing I would personally enjoy is the possibility of switching out the “outer shell” of the ring to add customization options such as changing the color from gold to silver or matte black and such. (Another note I would like to make was that I have the ring in the gold color option and, based on others’ comments, received my ring in good condition and is a true golden color, not bronze or orangy). As for the app side of recommendations, I would recommend adding exercises, activities, or goals as recommendations that can be completed throughout the day based on fitness or health goals one has. Additionally, it would be nice to see more types of exercises within the list of activities that can be logged as completed and for calorie burn accuracy. Now for the cons. The biggest con or complaint is the associated membership costs with using the Oura app ($6 monthly). Without the membership, the data presented through the Oura app is very limited and, based on their website, only gives access to the ring battery data, three daily Oura scores, basic profile information, app settings, and the Explore content section within the app. Additionally, the Oura API cannot be used, closing the door for accessing your health data with other apps, but you can still download all of your personal data through Oura on the Web in a csv or json format. Second, I noticed there were times where an activity was not tracked automatically. There were instances where I was doing weight training exercises and found that it was not marked on the app. Other times were I walked, ran, and started other exercises it was able to track well but not necessarily the times my heartrate spiked due to weight training. I would have to manually enter the activity in the app and the duration of it to log my exercise correctly. Last but not least, Oura does give some information about what it does with your health data it collects and does happen to specify in several cases the data it specifically uses for which purpose. On their website, it mentions that the health data can be used for their services, research and development to improve their products, marketing, for customer service communications, and for third party integrations (although how those services happen to use the data depends on their own privacy policies). Oura's site also adds that some data is “privacy-enhanced” including being anonymized to the point where it is no longer considered tied to someone specifically and that it complies with US state and federal data protection laws. If this still makes you a little weary, users are also given the option to submit a data subject request to “access, delete, or rectify their personal information.” Overall, I find the Oura 4 to be a very comfortable smart wearable, especially if you're looking into improving your fitness and health. While it's not a replacement for a smart watch, there are some added benefits and can even double as a wedding band.

The Oura Ring 4 is comfortable, stylish, and very accurate. I love how it tracks sleep and heart rate without feeling like I'm wearing a device. The battery lasts for several days, and the personalized recommendations really help. Highly recommended!

It's big, uncomfortable to sleep in, and not at all functional to wear all day. It's very uncomfortable. And the app's exercise tracking features are very limited. I didn't find the app very easy to use.

To use the app, you'll need to pay a monthly subscription; otherwise, it won't be much help. It might be more worthwhile to invest in a smartwatch, as it can offer similar features without the ongoing cost.

PRODUCT Oura Ring 4 - Smart Ring - Size 12 - Stealth Model:JZ90-54218-12SKU:6595532 QUICK REVIEW First time Convert from Fitness Band to Fitness Ring In most cases it seems more accurate than my fitness band (FB), and it allows me to return to wearing a nice watch instead. Use the Sizing Kit and choose your ring carefully. The edges are somewhat sharp, which makes choosing a finger even more critical. The app is not as clear / easy as my FB app, but hopefully it will continue to evolve. In short, I recommend the OURA 4, with a few reservations, but especially if you want to free up your wrist from a fitness band it is a good option. MORE DETAILS PROs - Solid very well build and nice looking - Easy to use and to get started - Long Life between charges - Fast Charging - Good (enough) app CONs - Very Large compared to a typical wedding ring - Edges are too squared off, almost sharp - App is sometimes hard to navigate to find what you want SIZING / EDGES I did not spend enough time with the kit. I ended up moving the ring from my left index finger to my right middle finger (the only other finger that fit). One big issue for me is that the edges are too squared off. I scrape myself all the time. I don’t mean I’m drawing blood (yet), but one main reason I moved fingers is that every time I touched my face, I scraped it on the edge of the ring. Even on my middle finger, I am scraping myself while washing my hair / face. PERFORMACE (Coming from FB) SLEEP TRACKING I found the ring to be especially more accurate in sleep measurement. How do I know this? We had a smoke alarm fail on us, and it was going off every few hours. FB gave me a sleep score of 85 and 7 hours of sleep. The Ring gave me a sleep score of 60 and 4.5 hours of sleep. In other words, the ring knew I was up tossing and turning and the FB did not. The Oxygen readings on the Ring are also more detailed as FB dumbed down the stats a few years ago. I have borderline sleep apnea (as diagnosed in a clinic). The Ring is giving me all sorts of warnings, while the FB says everything is within normal range. STEPS At first, when I had the ring on my left Index Finger the steps were almost identical to my FB and within 10% of my digital dress watch. However, once I moved the ring to my right middle finger, it started recording about 20% fewer steps. I don’t know if this is because it is a tiny bit more loose or Right hand Vs Left hand (maybe 11.5 vs 12). Or maybe the way I hold the dog leash (makes up most of my walking). THE APP There is nothing particularly wrong with the App, it just not as optimized as FB. For example, if you are looking at a stat (STEPS / SLEEP) it shows you a LEFT or RIGHT arrow to go to the previous day. However, instead of just taking you to the previous day, it brings up a full calendar and you have to pick the date. Of course, this is not the end of the world just wasted time hunting for things in the app. WHAT DO I MISS GOING FROM FB TO THE RING? - Vibration Alarms on FB - Seeing the Time at Night Both of these were easily solved by stealing the Digital Assistant Clock from my spouse’s side of the bed! FINAL IMPRESSIONS I am amazed at the size, accuracy and battery life of something like this. It is a marvel of miniaturization. I wish the finish was rounded and it was not scratching me. I wish it was a little smaller, but had I sized it right I probably would have moved it to another finger resulting in a smaller overall size. Finally, it would be perfect it is has some sort of vibration alert / alarm. Yes, I will replace my FB with the ring.

I bought it on December 2024 and now the battery is lasting just 24 hours!

I've been slowly watching not only the emergence but rapid developments in smart health devices over the last decade and I've been wanting to try out a device here or there. I do use an iPhone and Apple Health has helped me track my activity levels, but to really take it to the next level I needed a device that interfaced directly with my body for true monitoring and analysis. The watch just seemed somewhat cumbersome and I'm not a watch wearing kind of person (yet) so I started to look at rings and Oura offered their Oura 4 so I took a chance. What I do like is it is a two step process. First, you get a sizing kit which is a series of pre-sized bands and you simply try them on till you find the fit that works for you. You then submit your size to Oura (along with band color, type, etc..) and they then set up a ring custom to that size with its own serial number. Ring sizes vary from 4 to 15 and depending on your finger selection, the sizing can and will be different. For example, my thumb is a 15, pointer and middle are 13 and 12 respectively but my ring finger is an 11 and that is the finger I opted to use. One thing I do wish is Oura offered half size increments. 12 was a little loose but 11 was just a touch too snug. I went with an 11 seeing as I wanted to make sure it was making proper contact. An 11.5 would have fit just right. After submitting my size, I was sent the actual Oura Ring itself in very smart packaging that includes an excellent presentation. Inside, you get the ring and its charging stand which is also very well constructed. It oozes Apple type polish. Even the included USB-C cable is nice and lastly you get a very small manual that has numerous QC codes to point you to not only the app which is required but other resources. The ring itself is very polished and nice looking. Oura says to wear it at all times, but I still find myself removing it to lift weights though. Setting up the ring was very easy. Download the app, have it find your docked ring via Bluetooth, pair and you're finished. A firmware update was immediately available. The app will lead you through numerous steps to help personalize your goals and to enable Oura to interface with Apple Health if you're using an iPhone. Lastly, it will ask to be allowed to send you notifications. I'm still in the process of letting Oura learn my baseline health and sleeping patterns so that will take another week or so (it says it can take up to two weeks). I was happy to know the cardio and strength training I already do has resulted in a sub 50 nightly heartrate and a sub 60 resting heart rate. It is nice to see my bpm react accordingly when I'm eating foods not so great. I found out my sleep was just ok and needs improvement and how many times I wake up in the middle of the night. It will even remind you to get up and move around if you work a sedentary job like I do plopped in front of a computer. It sets initial activity goals for you and will let you know how you're progressing during the day of achieving them even through basic day to day tasks. The Oura app really is designed to take all the data it can from your finger and extract every bit of useful info to help you know where you stand and where you want to go. It is the crucial piece of the puzzle that brings everything together. This is what seperates it from the Apple Watch right now is the sheer amount of data it provides you compared to the Apple Watch. Initially when I was wearing the Oura, it felt like it was in my way and distracting because I'm not used to wearing rings or watches. After a day or so, I found myself not even noticing it and it has pretty much become an extension of my hand and doesn't get in the way. Perfect, right? Not exactly. A subscription is basically mandatory to really get the proper use out of what can be a pretty pricey piece of health tech. The upside is the cost is only $6 a month or $70 a year but that doesn't change the reality that you will need to continue paying more after the initial purchase. Another thing is unlike Apple Watch, it can not read your blood pressure from your finger. It also can not do Electrocardiogram (ECG) either like an Apple Watch. As someone who likes to monitor their blood pressure, this was a major letdown. Lastly, as mentioned at the beginning, offering half sizes would have really let me dial in my ring size instead of having to select a size either a tad too snug or a tad too loose. Having taken this first step into smartwear for health, I can say I am liking getting all this data about my day to day cardiovascular health and how it correlates with everything I do. I may end up stepping up to another device that can do blood pressure and ECGs in the future, but for now the Oura is giving me exactly what I need to start this journey.
