What the Apple Watch’s FDA clearance actually means
The FDA-cleared features aren’t supposed to be used by those under 22

Second, it’s important to understand that the FDA has “cleared” both apps, but that’s not the same as “approving” them. There are usually three ways to get the FDA involved in a new project, according to Jon Speer, co-founder of Greenlight Guru, a company that makes quality management software for medical device companies. The most advanced is FDA approval, which is done only for Class III products, or technologies that might have higher risk but also a higher benefit. (Think: implantable pacemakers.) Approval is the gold standard, and companies need to do a lot of testing to receive this designation.
