The polysomnography (PSG) is the gold standard so it will be used to compare with the app. So by definition, they are deemed as 100% accurate. When you do a “proper” PSG (see AASM for full details), the only reason it may not be accurate is if the test fails (ie leads coming off etc). When the test fails then the sleep laboratory will need to do another. When you get diagnosed with sleep apnoea, it is based on severity. A test result is not a simple parameter of either “yes” or “no”. It is based on analysis of multiple channels of data (ie breathing, sleep pattern, oxygen desaturation etc). Collectively, this outputs those arrays and then then a conclusion of if you have sleep apnoea and at what severity. By saying that, because multiple factors need to be collectively put together, it is very hard to misdiagnose sleep apnoea from the gold standard PSG.

What I would add to this is that I assume the app can easily monitor you over time.
