>Can't wait to get this in more devices.

Samsung received FDA approval back in February:

It works on a different monitoring method and requires 2 sleep cycles over 4 hours each in a 10 day window to start detecting.

>The feature, a software-only mobile medical app, uses smartwatch built-in sensors to monitor the user’s sleep for significant breathing disruptions associated with OSA. Users may track their sleep twice for more than four hours within a 10-day period to utilize the feature.

Yeah I'm generally a tech skeptic, but getting FDA approval for a real, common problem is a fantastic use for this kind of device. I did an at-home sleep study a few months ago, and while it wasn't an unpleasant experience, it did involve a long wait for an appointment, two trips to & from a specialty clinic, and awkwardly strapping on this device to sleep with overnight. That's a lot of barriers. Being able to do get a useful result for a very impactful health condition, just with an affordable piece of hardware that many people already have is a game changer.

Great job to the team at Apple for getting this together & getting real approval for it.
