Great for people that have to take their pulse frequently
I picked up the Wellue pulse oximeter recently and I’m really impressed. Setup was quick and simple, and the readings come up almost instantly. Compared to the ones I’ve used at doctors’ offices, the numbers match up really well — so I feel like I can trust it.I deal with POTS, and this has been a game changer. Not only does it give me quick, reliable readings on my oxygen and heart rate, but it also connects to an app on my phone. Everything records straight to the app, which makes it easy to track patterns and share with my doctor — either by showing them directly or sending the report.The screen is bright and easy to read, it’s comfortable to wear, and the automatic shut-off saves battery life. Overall, it’s a handy little device for anyone, but especially if you’re managing POTS or another condition where frequent monitoring is important. Highly recommend!

Works well and app is easy to use

Sufficient functionality, excellent value, and fit for purpose
I purchased this item because I had previously purchased another product from the same vendor (Wellue): the O2Ring Wearable Sleep Monitor, with which I am very satisfied (I wear it every night to alert me should my O2 level fall below a set value). So I had high expectations for this pulse oximeter, given how well that “O2Ring” and smartphone app worked together. Unfortunately, not all my expectations were met (but that is understandable, as I will explain). This pulse oximeter has just basic functionality in that, unlike the O2Ring, it does not [as I expected] have any recording capability. In other to examine its meaurements, the smartphone app has to be running; that I did not expect. The combination of the two (this pulse oximeter and its smartphone app, working together at the same time) can record its measurements, but not if the app is not running. Their O2Ring, in contrast, records its measurements within itself (so you don’t have to have their app running on your smartphone at the same time); the stored data are available for download afterwards. That’s fine, given that the “O2Ring” costs five times as much as this unit. Given the low price, I understand why there is no on-device data recording capability. Its function is, simply, basic. That said, what about the accuracy and responsiveness of this pulse oximeter? It appears to be just as accurate as a medical-grade, FDA-approved pulse oximeter I have (one which does not have any smartphone app monitoring capability), which costs ten times as much as this unit. Given the fact that you can (effectively) “snapshot” the recording data (in real time, so to speak) using the Wellue app in order to exhibit later (say, by taking a screenshot, or simply opening the app and showing the previously-recorded data to someone) along with the very low price of this pulse oximeter, I think it represents an excellent value; the combined function of the Wellue pulse oximeter and its smartphone app is superior to any other product I’ve encountered.

Product works, app is a little irritating
Everything works as expected. It’s a little thicker than none Bluetooth device. But the app has the irritating function of buzzing when the device is removed or turned off while recording a reading and can’t be turned off. Which if you’re taking a reading late at night or early in the morning the buzzing disturbs anyone in the room.

Great pulse oximeter
I recently had aortic heart valve replacement. This is an absolutely fantastic pulse oximeter. The app is great. I can send screenshots to my cardiology team.

I bought two!
I love the app and features. The pulse ox works well. A bit tighter than my old one but it’s because it’s new and it does the job great. I bought two of them.

Inaccurate Readings, Thicker than More Expensive Unit, Blue Tooth is Excellent
Poor accuracy! I was very disappointed in this unit. I have the more expensive version of the Wellue Pulse Oximeter and those reading matched when I was at the doctor’s office. This unit read 2 points lower that my other unit. Also note that this one is larger in thickness than the more expensive model, so it’s not as convenient to have in a pocket, although that’s a very minor complaint. I bought this unit as a backup in case I misplace the other unit. I refunded it and bought the better unit. Maybe my unit was just a lemon … but I’m much happier with the more expensive unit. Nevertheless, I love the connection to Blue Tooth and the memory on the units for a quick glance.
