“The Lookee Oxygen Ring and Oximeter represent exceptional tools designed for in-home self-monitoring. Their user-friendly nature and notable comfort render them optimal selections for individuals endeavoring to maintain a vigilant assessment of their well-being. Significantly, these devices boast the capability to promptly issue alerts and alarms, thereby ensuring that users remain apprised and proactive in their health management. Benefiting from an enduring association with the founder and CEO, Joe, spanning over a decade, I can confidently vouch for his resolute dedication to advancing clients' health objectives and advancing sleep wellness initiatives. In light of such a distinguished track record, it is with wholehearted conviction that I endorse the Lookee Oxygen Ring and Oximeter as a premier choice for those in pursuit of a self-assistive sleep monitoring apparatus.”

“Highly effective recordable pulse oximeter. I have 10 of these LOOKEE Oxygen Monitors and use them for titration purposes for my dental oral appliance used to treat Obstructive Sleep Apnea. It lets me know how my appliance is helping improve airway metrics as the lower jaw is advanced compared to their baseline test. Its very small and easy to use for my patients. They bring it in and i download the data on the LOOKEE app and print it out for their chart. I send the final pulse ox report to their Dr to show my results.”

“I love the design and the ease of use of LOOKEE Ring oximeters. As a sleep physician, I am so thrilled to have such a device available to help us to provide diagnostic and follow-up data to ensure patient's sleep disordered breathing condition has been adequately addressed. I have also tried it myself and it is quite comfortable and really easy to operate. As a patient and as a sleep physician, I would highly recommend LOOKEE Ring oximeters to other sleep medicine providers as well as to patients.”

“I treat patients with sleep apnea with oral appliances. I have sleep apnea myself. One night I tested Lookee Monitor myself with the appliance. I did great. My oxygen levels hardly ever dropped. The next night, I tested it myself without the appliances. The Lookee device told me that my oxygen dropped many times during the night. In addition, the next day I was tired and grumpy. It was great to document how well it works. It just told me how important it is to keep your oxygen levels up. So I highly recommend Lookee Monitor to track your CPAP or Apnea treatment.”
Good to know
Questions before your first night

Do I need my phone next to me while I sleep?
No. The ring keeps the whole night in its own memory. Sync it in the morning.
Will the vibration wake my partner?
No. It is a vibration on your finger, at one of 5 strengths. They will not feel it or hear it. You can also turn it off.
What is the difference between the O2Ring, the Ring and the Ring-Pro?
All three track oxygen, heart rate and movement overnight and work with the free LOOKEE® App. The O2Ring vibrates for both low oxygen and abnormal pulse, and tracks every second. The Ring and Ring-Pro have a vibration reminder for low oxygen, and the Ring-Pro adds PC software for longer reports.
Which finger should I wear it on?
Any of them. The thumb or index finger of your dominant hand reads most reliably.
Is it licensed by Health Canada?
Yes. LOOKEE® holds a Medical Device Licence. The licence numbers are on our licences page.
Can I return it?
You have 30 days to send it back, a 1-year warranty, and lifetime LOOKEE® tech support. See our return policy.
