Why track your blood oxygen continuously?

According to the American Sleep Association, the repetitive breathing pauses caused by sleep apnea during the nights can occur several times per hour and last for over 10 seconds. Continuous trackers like Checkme™ O2 Max supports long hours monitoring during your sleep, can help detecting all the Apneic events and Hypopenic events in every 2 seconds. However, normal oximeters only provide spot checks, which tend to miss 99.99% of your random SpO2 falls. 

We use proven technology trusted by:

Remind You to Breathe Well

A normal range of blood oxygen level is the key to start a new day. During the night, when your SpO2 started to fall below the preset value, the vibration will be activated. Unlike traditional sound alert system, it softly wakes you to change to a position that helps you breathe better. So sharing a bed with your partner won't affect his or her's rest. Checkme™ O2 Max, to ensure you wake up with an energetic morning.

Pricey—Oximeter Performs As Advertised

Pricey home use medical device! It appears the FDA concluded that this medical device is a safe and effective product as a legally marketed device. Unlike other oximeters, it is unclear why the product or software does not document or record the perfusion index (PI)—a simple explanation may provide clarity. Concerned that one area of the rubber thumb band wrap may not be durable. Must be very careful taking thumb wrap on and off. The area of concern appears thin; may be weaken and break after minimum usage. Then the user must purchase a replacement cable for an already pricey product. The medical device performs as advertised.

Good Monitoring, great support.

Tested with other oximeter, values are OK (aproofed by FDA)
Vibration and Sound test for high or low value of oxygen (only low) and puls, OK.
Great battery time. Work to gether with smart phone. High price but unique functionality.

Excellent sleep oxygen monitor

This little monitor does the trick. It is not that intrusive so it doesn't get in the way of my arm moving at night, but the sensor also stays put (been using it for about a week now and haven't had it come off). The software for the smartphone calculates numbers like the amount of time the saturation is >95 and the number of drops 4% or greater during the measured period. With the software for the computer, you can save this in report AND data exports to allow you to analyze to your heart's content.

Very helpful and informative

Glad that I bought the product. It gave me information about my quality of sleep and what I should do to get better sleep. Easy to use and reasonably comfortable to wear at sleep.

Suggestion to company: Enlarge the scale for the Motion chart as it wouldn't spike even when I am getting to and from the washroom.

Some peace of mind.

After my wife had departed and then come back to her body, she was put on oxygen again. Too much oxygen is what killed her in the first place, so I needed a device where I could monitor her daily status so I could adjust the flow meater to keep her from passing again. This device has an alert for low level of O2, but it should also have one for a high level of O2. At any rate I use the daily report so I can see her average throughout each night and I use the alarm if she goes below 87. I have been able to adjust the flow meaters on the two machines I have in the house and now have them each dialed in so she will average 93. The Checkme device has allowed me to accomplish that task.

My wife Rosemary has stage 4cancer

It's a great device that my wife wears 24/7 she wears to go to sleep it vibrants when her oxygen levels drop so can regulate her oxygen day and night she's on oxygen 24/7 thank God for this wonderful device to make it easier for me since I'm my wife's care taker .

Great monitor with helpful support

I have bought and owned at least 4 different spo2 monitors such as checkme doctor, checkme max, checkme be4 max, i own all and have tested them all and they all matched readings from 1 hand using at same time on different fingers

and can say there accurate i got my 1st 1 in 2019 and then bought a family member the new max model in may2021 due to there ill health and due operations on there lungs and a weak heart

The max model has spo2 monitor plus a pulse rate monitor which both have an alarm system when they drop below a certain level then it beeps and vibrates

Support are very helpful with replacements when it comes to replacement charge/data cables or of finger sensors am a restless sleeper and due this sensors have malfunctioned and wellue have kindly replaced sensors as there warranty and guarantee is for a full year from purchase and there fast to reply within 24 hours so am very happy with there support system

Great Device and easy to use.

This device is of very high quality. Comfortable on the finger and the wristband.
Software interfaces once you open the app and downloads your nightly results automatically. This is a medical grade device with data that quite honestly could add years to your life because sleep apnea as a result of an airway restriction (snoring) is detrimental to your cardio muscle. The SPo2 alarm can be set for audio or vibrational mode and I learned that my snoring issue only occurred when I slept on my back with resultant jaw opening.
5 star product and any questions are immediately answered by product support.

O2Max

My husband mentioned I stop breathing during the night. Had two Sleep Apnea tests. Results are not serious enough for a CPAP. I didn’t really want to use that device if I didn’t have to. Doing various research and stumbled across this device. IT IS PERFECT for me. You are able to set vibrations (5 settings) to wake you during the night. I have it set at 85% and it WORKS. The app is very helpful and gives you a running daily report of how your night of sleep went. The support has been extremely helpful during the adjustment period. After 10 days I’m resting better, and my husband no longer has to poke me when he feels I’ve stopped breathing.

Hi Janice,

We're glad that your Checkme O2 Max is making a difference in your life. If you need more assistance or have questions in the future, please don't hesitate to reach us again!

Wish you and your family in good health.

I LOVE My Checkme™ O2 Max Wrist Oxygen Monitor

I am so glad I invested in the wrist monitor. I have been able to easily monitor my oxygen levels and really appreciate the alarm to help me not drop to low. I have set my threshold higher to keep me in a good range before problems happen. Checkme is comfortable to wear and I am impressed with the battery life of my monitor. I didn't expect the battery to keep a charge all day long but it does! Couldn't be happier and am so glad Wellue will stand behind the customer if the monitor stops working.. Thank you so much Wellue
