Product description



How to ensure accurate measurement results?
Wear it on your middle finger or a comfortable fingertip, avoid pushing against the bone, and keep your finger still for a few seconds to read stable data.
Why does the APP data disconnect?
Android phones may disconnect Bluetooth after prolonged screen sleep. We recommend keeping the screen awake during use.
Does the device have an alarm alert?
The device itself has no alarm sound, but the connected APP allows custom thresholds. Your phone will beep if levels exceed the set range.

Continuous Blood Oxygen Monitoring Meets Smart Technology
The Pulse Oximeter O2 Ring Oxygen Monitor is an excellent device for anyone looking to continuously monitor their blood oxygen saturation (SpO2) and pulse rate (PR) with ease and accuracy. This rechargeable pulse oximeter offers the convenience of continuous recording, making it ideal for health-conscious individuals or those managing respiratory conditions.One of the standout features is its compatibility with a bundled app, which provides detailed reports of your oxygen levels and pulse rate over time. This allows users to track their health trends conveniently from their smartphones, enhancing the overall monitoring experience.The ring design is comfortable and non-intrusive, allowing for all-day wear without discomfort. The device is also user-friendly, with clear readings and reliable performance. Its rechargeable battery ensures that you won’t be constantly replacing batteries, making it environmentally friendly and cost-effective.Overall, the Pulse Oximeter O2 Ring Oxygen Monitor is a smart investment for continuous health monitoring, combining accuracy, comfort, and modern technology in one compact device.A new wave of health monitoring technology has arrived with the Pulse Oximeter O2 Ring Oxygen Monitor, designed to provide continuous, real-time tracking of blood oxygen saturation (SpO2) and pulse rate (PR). This rechargeable device stands out for its sleek ring design and seamless integration with a dedicated mobile app that delivers detailed health reports.Unlike traditional fingertip pulse oximeters, this ring monitor offers the convenience of non-stop monitoring without interrupting daily activities. Its rechargeable battery ensures long-lasting use, making it both eco-friendly and economical.Health experts highlight the importance of continuous oxygen monitoring, especially for individuals with respiratory issues or those recovering from illness. The bundled app not only records data but also generates comprehensive reports, empowering users to better understand their health trends.With its user-friendly interface and comfortable fit, the Pulse Oximeter O2 Ring Oxygen Monitor is poised to become an essential tool for proactive health management.Performs well, easy to use, has both phone app and PC app. The data can be loaded into OSCAR (Open Source CPAP Analysis Reporter). For me, it is less noticeable than the rubber cup finger sensors with a separate wrist component. I started with one of those because it was cheaper, and if you only need it for a short time or very occasional use, that style might be fine. But, I use it every night.Small & stays on your finger. I am a very restless sleeper & it has never fallen off. Pretty accurate. When compared with my regular pulse oximeter, it was only 1-2 points off if at all. It has an adjustable vibration tone that has never failed me & best part, you download an app to your phone & it saves the dats to show your doctor. Love this little thing!!I’m always out of breath and wanted something that would warn me when my o2 level dropped. I down loaded their app and set it to go off at 85%. The finger part vibrates when I go below my set point, and you can set that at whatever you want. When it goes off I know I need to sit down and rest and let my o2 level go back up. The device will save my daily info and then download it to my phone app whenever its USB is unhooked. I haven’t quite figured out all the info in the app yet, but I can look at my o2 level in real time during the day plus my o2 score for the entire day. The battery will last all day, plus you can monitor the battery level on the app anytime. I unplug the device from the ring part at night and recharge it.

Pulse Oximeter Ring
A solid ring oximeter for the price, especially if you need to monitor your stats consistently but don’t want to spend big on a smartwatch. The readings are accurate — on par with pricier devices I own — and I love that it syncs with the iPhone Health app. The companion app is easy enough to navigate, though I’d love to see more features and third-party integrations added over time. The ring itself is comfortable for everyday wear, though it can feel a bit bulky on smaller hands. A great budget-friendly option for staying on top of your health. Battery life is EXCELLENT, has a good amount of features without being overwhelming. Incredibly easy to use and very durable.

Accurate and Easy-to-Use Pulse Oximeter Ring – Great After One Week of Use
I purchased this pulse oximeter ring about a week ago, and it has quickly become a handy health gadget to keep around the house. The ring design is comfortable and lightweight, making it easy to pop on my finger and get a reading in just a few seconds. I like that it connects to the app via Bluetooth so I can see trends and values over time, which is more informative than a standalone device. It feels well built and hasn’t given me any trouble syncing with my phone.In everyday use the readings seem consistent and clear, and the display in the app makes it easy to understand my blood oxygen and pulse data. I appreciate how intuitive the app is — you don’t have to dig through menus to find the latest numbers or historical charts. It’s also nice that the device automatically shuts off when you’re done, saving battery life without extra effort. For casual at-home monitoring, this has been a reliable tool so far.The only minor issue I’ve noticed is that the battery life isn’t quite as long as some fingertip models I’ve tried, but recharging is quick and straightforward. I also haven’t had to deal with any awkward placement — the ring fits securely without sliding around. Overall, after using it for a week, I’m glad I bought this and feel more confident tracking small changes in my readings. I would recommend it to anyone looking for an affordable, user-friendly oximeter option.

Trash
It was working for two days, after that oxymeter “refused” to pair with my phone. I tried a different phone, the same thing. I call Amazon support and they redirect me to Ask questions site, I paid $5 and still not help. That site tried to change my credit card with $55, so I blocked credit card. I have a oxymeter that went straight to trash can. Do not buy it.

Good, Reliable, Comfortable and Accurate
I really like this little ring at first, it turned out to be such a neat gadget. It’s lightweight, smooth, and super comfortable to wear, I barely notice it once it’s on.The fact that it tracks everything automatically is really cool . The battery life is great too. I don’t have to charge it constantly, and when I do, it charges pretty quickly. The app is easy to use and gives clear reports that are actually simple to understand, and very functional.Overall, it just gives me a good sense of knowing. It’s one of those little devices you don’t realize you’ll appreciate so much until you start using it. I’m really happy I bought this one, it feels well-made, reliable, and thoughtfully designed.

Functional, But Too Dependent on a Poor App
i got this Pulse Oximeter O2 Ring to monitor my levels, and while it technically works, the overall experience is mixed.The build quality feels kind of cheap considering the price point. It is lightweight, but it doesn’t have the premium feel I was expecting.My biggest issue is the software. The app is lackluster and frustrating to use, which is a problem because the device relies heavily on it. I honestly wish it didn’t need an app at all. It would be much better if it could just function as a standalone unit without forcing you to pair it with a phone to get the most out of it. If you want something simple that doesn’t require fiddling with your phone, you might want to look elsewhere.
