The Kenek Edge pulse oximeter app measures blood oxygen and heart rate using a hospital-grade finger sensor attached to your mobile phone or tablet. It can record and save data continuously for up to 24 hours. The saved data can be exported and graphed to show the details of heart rate and blood oxygen.

The app generates an audio signal that drives the sensor, shining a non-invasive light through your finger tip, receiving a signal back. The app continuously analyzes the signal and produces vital signs measurements that are highly accurate and reliable.

The Kenek Edge pulse oximeter is designed to help you to achieve your health and wellness goals. Saved data can be exported via email in CSV (comma separated values) format. Kenek Edge is also integrated with HealthKit.

The Kenek Edge pulse oximeter is a fast and accurate way to measure pulse rate (bpm) and blood oxygen saturation (SpO2 %). Without a sensor, the full-feature app operates with simulated data, so users may explore the features.

SpO2 % - the percentage of functional arterial blood oxygen saturation
Heart Rate - the number of heart beats per minute (bpm)
SQI - signal quality index

Kenek Edge and app

This unit works extremely well. It does everything it claims it will do. Including 24 hour recording. Their support and service is also very good. You must read all the info on how to set it up. The app has instructions at bottom, see the customer service tab. You need to turn down the screen brightness when your recording for extended time periods. This unit has been improved considerably since it first came out. Another point, I suggests that you use a sport arm strap if you want to record for long periods at night. You can also use a piece of medical paper tape to keep the sensor in place if you turn and toss while you are sleeping like I do. It is amazing what this unit will do for it’s low cost. On the iPhone 7 and up, you will need a audio lightning adaptor to plug the sensor into.

Great app, device & support!!

Set up easy and it worked fine first night of monitoring. I had a problem getting my data report emailed to myself but it was a problem with my phone and not the app. None-the-less, Michael at Tech Support was a patient, knowledgeable and friendly helper!!! Thanks!!!

Needs a separate apparatus

It's not what I'm looking for, as I was hoping to find something that uses the flash
