Are you looking for guidance on which one out of the many options available is the best for you?

After heavily researching the best overnight pulse oximeter options to meet your wireless oxygen monitoring needs, I’ve found that it really comes down to two brands: Wellue (in collaboration with Viatom technology for some products) and Lookee.

For my full Wellue O2ring review please click here.

To successfully conduct home overnight oximetry, I’ve determined that a pulse oximeter that fits like a ring (like the two devices reviewed here) is the best option. This is because they:

Fit comfortably

Stay on securely while sleeping (unlike fingertip pulse oximeters)
Don’t have any wiring that could be at risk of disconnecting overnight

The Wellue O2Ring and Lookee Ring Sleep Oxygen Monitor are both ring sensor overnight pulse oximeters with similar features and price point.

Therefore, to help you decide which is the best overnight pulse oximeter for you, I’ve created a helpful side-by-side comparison of these devices. [Check here my Full Welue O2Ring Review.]

One of the coolest things about it is that it doesn’t just clip onto your finger like your average oximeter.

Nope, it’s a smart ring that you wear on your finger, making it super comfortable and convenient.

You won’t even feel like you’re wearing anything special, yet it’s working its magic behind the scenes.

If you’re already itching to get your hands on the Wellue O2Ring (or, well, your finger in this case), I’ve got you covered.

My #1 Pick: Wellue O2Ring

The Wellue O2Ring is an extraordinary oxygen saturation tracker, as firstly, it’s the perfect size and fit.

It fits comfortably over the thumb or finger, leaving the rest of the hand free for movement.

The ring fit allows it to stay on securely throughout the night and doesn’t slip off. The ring perimeter is 2-3.2 inches (50-82 mm) and adjusts to fit within all finger sizes in this range.

This pulse oximeter collects an impressive amount of data during one recording session, as it continuously tracks oxygen levels, pulse rate, and motion every second.

It has a built-in memory for data collection, but data can also be stored using the Android or iOS app or the Mac or PC software.

The app or software provides overnight oximetry interpretation and gives you access to detailed analysis reports of blood oxygen levels, heart rate, and body movements.

It produces high resolution trend charts with 4-second intervals. You can also easily generate professional PDF or CSV reports to instantly send to your doctor for further analysis.

I know this is a lot of talk about data, and you might find it overwhelming. The good news is that the reports are easy to read if you have the right guidance.

Now let’s get to one of my favorite features of the Wellue O2Ring. It vibrates when low oxygen levels or abnormal heart rate is detected.

The vibration feature can be customized by intensity of vibration, what you want it to vibrate for (ie, oxygen, heart rate, or both), and at what threshold for each.

Furthermore, an added benefit of the vibration alarm is that if you’re sharing a bed with a partner, it only wakes you up (unlike a sound alarm, which might wake up your partner).

Recharging the device is easy, as it only requires USB connection. Furthermore, the battery life of 12-16 hours is more than sufficient, as you can get about two night’s use out of it before it requires a recharge.

Pros and Cons

Pros	Cons
Ring fit is comfortable, secure with no concerns for disconnecting overnight	Some reported app issues
Vibrates when oxygen levels are below normal	Some dislike the software
Can be set to vibrate at a customized oxygen level and vibration intensity	Does not sync with Apple Health
