This is a fantastic tool to use if you suspect you are having breathing issues at night during sleep. I had been having daytime tiredness that I suspected was due to poor sleeping, and my Apple Watch previously showed some fairly random low O2 numbers and I wasn't sure if it was inaccuracy from the watch, or an actual problem. When Apple rolled out the iOS18 sleep apnea screening feature, I noticed that I was having elevated breathing disturbances, and got an apnea alert from the watch.I decided to buy this Wellue O2 ring since I saw it recommended on several websites. It's been a great purchase, and showed that I was indeed having many oxygen drops throughout the night. Some even as low as down to 75%.Since then I've been able to take action. I initially used a Woody Knows sleeping backpack to force myself to sleep on my side rather than my back, and my O2 score went up to 9.6 to 9.9 with this, with little to zero O2 drops. I didn't really like having to strap a backpack on each night, so I have since purchased a Night Shift electronic device which monitors my sleep position and then vibrates to stop me from sleeping on my back, and this is working great. I continue to use the O2 ring to monitor the effectiveness of the different remedies, and it shows the Night Shift device makes a big difference.I highly recommend getting the O2 ring if you suspect you might be having issues with your sleep (loud snoring, awakenings during the night, morning headaches, tiredness during the day). This device could save your long term health!

I have 3 to 4 significant oxygen drops every night which can result in me waking up with a headache and a racing pulse. For a year, I have been using a bracelet oximeter with cable finger attachment to wake me up when my O2 % drops to 85%. Unfortunately, over time, the strap fastener has became insecure and falls off during my sleep, so I broke two finger cables in quick succession. Wellue replace one cable free of charge which was much appreciated but the failing wrist strap fastening was still a problem. Buying the new Viatom Pulse Oximeter has been fantastic for me, it stays secure on my finger all night and works extremely well, waking me up when my O2 levels crash down. I have worn it for three weeks now and I wouldn’t want to go to sleep without it. It been reliable, so easy and comfortable to use. Well done Viatom.

I love my Viatom/Wellue Ring.I've being wearing one of these Rings, overnight every night, for almost a year now. initially it helped me. I had no symptoms of apnoea (I don't snore, I don't wake with a gasp, I don't have any daytime sleepiness), but I did wake in the night feeling like my circulation had got stuck. I wore a standard oximeter one night, and was shocked that it went off several times. I video recorded myself sleeping, and there were no symptoms of apnoea. I then bought my Wellue ring.The data from the Ring was great. It demonstrated that I was definitely suffering from oxygen drops, and quite frequently and severely. I did an at home sleep study, which discovered that I do, in fact, have apnoea even though I was not showing any symptoms.Fast forward 8 months, and I was visiting my parents with my brother. I thought he might have apnoea, and convinced him to try my Wellue Ring over night. He did it, mainly to shut me up I think. The next morning, i loaded the data from the ring, and we were horrified by what we saw.My brother contacted his GP to try and arrange a sleep study. He bought his own Wellue Ring so he could monitor himself in the meantime. Because the results on the Wellue were so severe, he ended up paying for a sleep study. The results of the sleep study reflected what we saw from the Wellue Ring. He has severe obstructive apnoea. He has just started on CPAP therapy and the difference is amazing.I can say, without exaggeration, that the Wellue Ring probably saved his life.The Ring and App are easy to use. The graphs on the app could be clearer than they are, but they are very useable. Its possible to generate PDFs to share the data with, eg, your GP if you want to demonstrate that you need a sleep study.I recently bought a Galaxy 5 watch, and my Wellue RIng is more accurate than the watch.
