Sam Cavaliere, a San Diego tech worker, considers himself in average health, though the 47-year-old admits, “I can always stand to lose a little weight.” Like a lot of iPhone owners, he uses Apple’s Health app to keep track of his weight, his exercise routines and how many steps he takes in a day.

Now the app is also storing his health records.

Since last March, Apple has been rolling out a feature that allows people to store their medical records in its Health app. UC San Diego Health, where Cavaliere sees his doctors, is one of more than 200 health care providers around the United States using the health records feature.
