Something not good here.

(Preliminary results from ResApp’s study achieved 86% sensitivity and 83% specificity for identifying patients with an apnoea hypopnea index (AHI) greater than or equal to 15 (patients with moderate and severe sleep apnoea) compared with simultaneous in-laboratory polysomnography scored using the current 2012 AASM scoring criteria. The area under the receiver operating characteristic curve (a standard measure of how well a test distinguishes between two diagnostic groups, where a value of 1 represents a perfect test) was 0.91. Similar results were obtained for identifying patients with AHI greater than or equal to 30 (patients with severe sleep apnoea). These results were obtained using ten-fold cross-validation on a large cohort of 731 patients, 62% of which were male. The mean age of patients was 53 (range 18-87) with a mean AHI of 24 (range 0-196). )
re "

I haven't read the details you refer to, I'm a bit behind on RAP announcements,
But, would it not be true that you don't snore if awake, and therefore any snore sound must be taken while you are asleep, and that the app therefore measures the snore sound waves only while you are asleep?

(But, would it not be true that you don't snore if awake?)

Really tough question...many a time have had the missus dig me in the ribs to stop snoring and I could have sworn that I had been awake.
