What FDA cleared it for
The Indications for Use statement, verbatim, from the decision document.
The Sleep Apnea Notification Feature (SANF) is a software-only mobile medical application that analyzes Apple Watch sensor data to identify patterns of breathing disturbances suggestive of moderate-to-severe sleep apnea and provides a notification to the user. This feature is intended for over-the-counter (OTC) use by adults age 18 and over who have not previously received a sleep apnea diagnosis and is not intended to diagnose, treat, or aid in the management of sleep apnea. The absence of a notification is not intended to indicate the absence of sleep apnea.
The product code's definition, from FDA's classification record. An over-the-counter device to assess risk of sleep apnea is intended to provide a notification of the risk of sleep apnea in users who have not been previously diagnosed with sleep apnea. This device uses software algorithms to analyze input sensor signals and provide a risk assessment for sleep apnea. It is not intended to provide a standalone diagnosis, replace traditional methods of diagnosis (e.g., polysomnography), assist clinicians in diagnosing sleep disorders, or be used as an apnea monitor.

THIS IS PERTAINING TO THE WHOOP WEARABLE ARM BAND. IT BURNT MY ARM TWICE, WITH NO RESPONSE OR ADVISE ABOUT SOLUTIONS FROM THE MANUFACTURER. THESE ARE NOT SERIOUS BURNS THAT REQUIRE HOSPITALIZATION, BUT THEY ARE SERIOUS ENOUGH THAT I HAD TO TAKE IT OFF, AND USE OTC BURN CREAM FOR A WEEK OR SO BEFORE IT HEELED ENOUGH TO NOT BE PAINFUL TO THE TOUCH.
