Review: Best of the Lot - Did a lot of research and bought this device. It works great. There are several pluses: Easy to use. Finger strap is great and prevents the device from accidentally falling off The reports are in depth and I share these with my doctors I feel this is medical quality and the company actually follows up. What great service.
Review: Should it be looser-fitting for bedtime? Yes, but with a little retro-fitting, it works fine... - What other reviewers said is true - it fits tight, and is definitely annoying when you go to bed. I felt like my pinkie was in a clamshell and the clam didn't want to let go. Very uncomfortable. BUT, read on... About the Retrofit: Looking for a solution, I rolled up two very small bandaids into little "bandaid cigars" and inserted one on each side of my inserted finger (alongside my finger) which provided a slight (very slight) "opening" of the clamshell to support my finger. When I did this, it worked well for comfort, I did not feel like my finger was squeezed an a clamshell all night long, and the device still recorded my data even with the retrofit keeping it just a tiny bit less tight. The key here is to insert a little extra padding on the white edge where the "clam" closes -- vs. a lot of bulk -- just a hint of extra padding so your finger isn't squeezed so tightly. If you opt to ry this, just make sure it's still recording data (look for the blinking light). If it's not, you've payed it open too far and it's not picking up a reading. About Keeping it on all night: It fell off once during each of the 2 nights I used it (I reconnected it when I woke during the night - then it continued recording data). So far I have not used the velcro strap designed to help keep it on - haven't found that necessary - I don't move that much during sleep. Finger choice: My physician friends told me any finger works for reading your data, so the choice is yours. I put it on my left pinkie since I'm right-handed and it's convenient to have a hand free during the night. Connecting & Reporting to the App: Setting up the app was super easy. Not entirely sure how to make sense of the report it spits out into the App, but the data looks clean and the graphics are pretty simple, so I'm sure I'll figure that out. Batteries: It's an energy eater - you need to replace the batteries (2 AAA) every 3 nights or so. I use rechargeable, so it's no biggie. Rechargeable batteries and chargers have come down a lot in price the past decade or so, so it's the way to go. Rechargeable batteries require special recycling, so don't throw them in the regular trash give them to your local recycling center. So far, happy with the purchase. It's nice to have a pulse ox that records data.

## Features

## Questions & Answers

**Q: Does this unit have an alarm?**
A: no

**Q: Can this system write my results into the apple health app (healthkit)?**
A: Yes. As noted above, the oximeter collects data second-by-second and gives you its results (via its own app) in those fine-grained increments. Apple Health only allows for data on a minute-by-minute basis, so the oximeter data gets summarized minute-by-minute when sent to Apple Health.

**Q: can it detect if you had a nocturnal seizure?**
A: I am not really sure. If tracking oxygen levels while you sleep and certain levels can be used to indicate a nocturnal seizure then i would not see why not. This question may be more for a medical professional.

**Q: can you export raw pulse rate data to file?**
A: what do you mean by "raw" pulse rate?

### ⭐⭐⭐⭐⭐ A literal life saver!
*by S***. on December 4, 2025*

For months I was waking up with massive migraines, feelings like I hadn't slept in weeks, fatigued and brain fog constantly. I'd talked with my doctor about setting up a sleep study but they were backlogged. Every day I felt progressively worse and worse. Then I though "I'll just do my own sleep study, see if I really do have apnea going on". I ordered this device and was absolutely shocked at what I saw. I knew it wasn't good, but not this scary! I was dipping clear down to 68% oxygen saturation (65% is where your lips and fingers turn blue). I showed my Mom this first graph and she just happened to have an extra CPAP machine stored away. She got me setup and the first night was incredible! I felt like a new human! (2nd graph). This all went down 2 months before my actual sleep study which confirmed, yep, I have a pretty good case of sleep apnea. I feel like without this tool, I genuinely wouldn't have survived! As for the device itself, it works pretty flawlessly! It's comfortable, stays on well through the night and uploads the data to the app with ease. Part of my nightly routine now! Only thing that's kind of a bummer is how quick it runs through AAA batteries (a set every 8 days or so). I picked up some rechargeable batteries, which I'd highly recommend. Beyond that, solid device, well worth the price! If you suspect sleep apnea (you snore, you wake up fatigued, you have brain fog, mornings are way more rough than they used to), BUY THIS!
