The Health app keeps you motivated by showing you how much you move. It combines activity data from iPhone — like your steps and distance traveled — with metrics from third-party fitness apps. And Apple Watch automatically records simple but meaningful kinds of movement, like how often you stand, how much you exercise, and your all-day calorie burn.

The Health app lets you keep all your health and fitness information under your control and in one place on your device. You decide which information is placed in Health and which apps can access your data through the Health app. When your phone is locked with a passcode, Touch ID, or Face ID, all of your health and fitness data in the Health app — other than your Medical ID — is encrypted. Your health data stays up to date across all your devices automatically using iCloud, where it is encrypted while in transit and at rest. Apps that access HealthKit are required to have a privacy policy, so be sure to review these policies before providing apps with access to your health and fitness data.


Public health has been described as "the science and art of preventing disease, prolonging life and promoting health through the organized efforts and informed choices of society, organizations, public and private, communities and individuals."[51] It is concerned with threats to the overall health of a community based on population health analysis. The population in question can be as small as a handful of people or as large as all the inhabitants of several continents (for instance, in the case of a pandemic). Public health has many sub-fields, but typically includes the interdisciplinary categories of epidemiology, biostatistics and health services. Environmental health, community health, behavioral health, and occupational health are also important areas of public health.

Health, as defined by the World Health Organization (WHO), is "a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity."[1][2] This definition has been subject to controversy, as it may have limited value for implementation.[3][4][5] Health may be defined as the ability to adapt and manage physical, mental and social challenges throughout life.[6]
