“It’s really strange to me that you can easily pull up all of your spending record on your credit card going back a long way in every detail, yet your health is way more important and you don’t have easy access to your health information,” said Jeff Williams, Apple’s chief operating officer. “We want to make sure that consumers are empowered with information about their health.”

Tech giants including Apple, Microsoft and Alphabet, Google’s parent company, are going head-to-head to obtain a larger slice of American health care spending, which amounts to more than $3 trillion annually.

Apple, more than the others, has been reticent to publicize its long-term vision for health technology. But recent product introductions, like the new health records feature, highlight how focused Apple is on using its iPhone, Apple Watch and apps to give people more control over their health care.

In addition to the iPhone Health app, Apple has developed ResearchKit, software to help researchers develop iPhone apps to conduct health studies, and HealthKit, a platform that allows consumers to share health data on their iPhone or Apple Watch with health and fitness apps. Apple is also sponsoring clinical research, called the Apple Heart Study, at Stanford University to determine whether an app for the Apple Watch can detect irregular heart rhythms.
