LOOKEE Ring Continuous Pulse Oximeter - Wearable Oxygen Monitor with Vibration Reminder for Low O2 - Rechargeable Blood Oxygen Saturation Tracker for SpO2 & PR - Free APP with Reports

Accurate, convenient, logs records and has printable reports for each log. I'd give it more than 5 stars if I could. That being said, it could still be improved upon if the device readout was larger and/or brighter, and if there was some sort of summary reporting or graph of historical data. Oh and an alert for heart rate not just O2. I bought this years ago to determine if I had sleep apnea (I don't). It is much more accurate than my Garmin watch as far as O2 saturation readings. After Covid I started monitoring my daytime O2 and noticed drops that coincided with heart rate spikes from doing nothing more than standing and/or walking around the house. I started to doubt it's accuracy but the clip oximeter was giving the same readings (although slower). Turns out I had POTS (postural orthostatic tachycardia syndrome). The holter monitor and echocardiogram I had a few months ago didn't pick up on it. I even bought a Wellue ring monitor to compare this with and the results are similar. The Wellue does not show the heart rate and O2 side by side though, and the button is hard to get to work, making this model far superior. Now I'm using it daily to warn me when my O2 falls below 90% and I use the alert on my Garmin for when my heart rate accelerates past 100 - then it is time to sit or lie down. If it weren't for this device I'm sure I'd have passed out and face planted by now.

Discovered at Pulmonary Rehab, where the therapist had a (medical grade) pulse ox attached to my forehead (while I continued to wear my new LOOKEE ring pulse ox with alarming, on my left thumb, that the LOOKEE device was VERY inaccurate -- to the point of being useless. The discrepancy in oxygen saturation readings bounced around, but at some point reached EIGHT POINTS -- the Lookee was alarming (vibrating), warning that my oxygen saturation was down to 88%, while the medical grade pulse ox saw my oxygen saturation as at 96%. I tried contacting LookeeTech support three days ago, but despite their promise of 24/7 support, have still not heard back.

My doctor told me about this ring as a first step toward identifying sleep apnea. It's very easy to set up the app and to connect it with the ring. The readings come easily in the morning once you remove the ring from your thumb (suggested place to wear it.)

Im thankful for this little device that is helping my husband get better rest. A few nights I woke up to him gasping for air, as he stopped breathing while sleeping. SCARY! The doctor agreed this was a good plan to use and monitor the results with him. It gently vibrates on his finger, encouraging him to roll over and breath properly. Wonderful little helper so I can sleep better too! Downside is the app was a little hard to get to know. If you don't upload data in the morning you lose it. It took a bit to get on that, but it is ok.

This is a good meter for at night. I wear it to bed and in the morning you can tell how your oxygen and heart rate were during the night. You can set the lowest number (oxygen) and it will vibrate when it goes below.

I almost never write reviews, but I feel I must for this device due to the huge disappointment it caused. With a comparatively high price, it significantly falls short of expectations and proved unusable for the described purpose. The reason is that the device often becomes wildly inaccurate, as the measurements for blood oxygen greatly vary between 80-100% within mere seconds.* Measuring SpO2 with a professional oxygen meter at the same time (and on the same finger) shows massive differences (i.e. the professional oxygen meter showed stable measurements of normal values while this device's measurements jumped all over the place). Changing fingers (as suggested per the manual), finger positions, as well as switching between left and right hands, and measuring many times, sadly did not improve this. (*These periods of high measurement variance made up about 50% of total use time.) Furthermore, due to this inaccuracy the device keeps firing off the vibration alarm incessantly. So, even if you get lucky to successfully make it to sleep with it, you'll likely be woken up again very soon because the device thinks oxygen deprivation is imminent. Of course, on a funny note, there is probably a point to be made that such false positives could be better than false negatives! That is, unless you think that you require sleep. On the positive side, the look and feel of the device is rather nice. As is the non-intrusive iPhone app, which is easy to use and appears well organized. But in a way that pains me even more, that so much effort has been put in to make the design look good, but so little on the accuracy side, to the extent that the device is unfit for any meaningful practical use. For an oxygen meter with vibration alarm, it is just not enough if it only works somewhat reliably about 50% of the time. Lastly, it is disappointing, yet maybe not surprising given the above, that there is a no-return policy for the item.

I have been using this for a week now. I am pretty sure that everyone should have one of these. At least everyone that has trouble getting a good night’s sleep...and that is pretty much everyone, isn’t it ? First, the design. It is as simple as possible. In fact I had trouble with it at first because I was over thinking it. Charge it, turn it on, put it on your thumb. Done. Now go to sleep. when you wake up, just open your app, and then take off you unit. You don’t have to like it with Bluetooth or anything. Just hold it close to your phone or iPad and it will download automatically. Tons of information here. Heart rate (the spikes are when you turn over or wake up). O2 level is shown minute by minute and you can see how many times you stopped breathing, your levels dropped, and you can see when the corresponding heart rate increase when you wake up. They say as much as 40% of the population has sleep apnea. Do you ?
