I think you make great points. I suppose you put forward a view rather than a question for me, but I'm ok with that.
Nonetheless in response to your views, I wish to point out the following:
1) The US Preventive Services Task Force findings was in 2017. There was no Sleepcheck then. There was only home sleep study in 2017, which costs $300-$400 a pop, and is cumbersome to use. Even if governments were happy to pay for that $300-$400 a pop, the test was not scalable and not readily available for mass population screening, . The cost-benefit certainly did not stack up, for population screening using home sleep study. It still doesn't, and never will.
2) Fast forward 3 years, this is 2020, and Sleepcheck has become available. It's almost as accurate as home sleep study. It's cheap at $8 a pop. It is scalable, non-invasive and user friendly, ready to be applied to the masses. I acknowledge that no cost-benefit analysis has been done for Sleepcheck in mass population screening, and so you do have a point, that this is why we don't have such program as yet. But IMO, I wouldn't be at all surprised that such cost-benefit analysis will come in the near future, and the results will be favourable for Sleepcheck to be used as a mass screening test for at-risk population.
3) The RACGP article is historical. The link that you posted:
https://www1.racgp.org.au/ajgp/2019/april/adult-obstructive-sleep-apnoea, dates back to April 2019, when Sleepcheck was not yet available, so that link is highly irrelevant. In any case, clinical guidelines typically lag best practice by 2-3 years. Quite often (more often than not, actually), best management workflows have become firmly established, way before official guidelines come out, so I don't place much weight on these "guidelines" at all.
4) To my knowledge, Sleepcheck is the only clinically proven app for OSA screening. The other dozen that you refer to, including Snore Lab, are not backed by research evidence, and certainly unsuitable for clinical use. Please correct me if I'm wrong, by quoting links to relevant research for these alternative apps.
As usual, the above are my opinions only. Please DYOR and make your own decision accordingly.
