It is important to acknowledge that arterial oximetry results can differ across manufacturers; therefore, comparing vital readings or logged data with those from other oximeters is not advised. For the most accurate measurement of arterial saturation, use the thumb or middle finger.

I have sleep apnea for a long time, but trying to sleep without CPAP now. This is exactly what I needed to track my saturation levels. App is easy to use and seems accurate
