Because they’re accessible to patients both at home and on-the-go, health apps are a part of the movement towards mobile health (mHealth) programs in health care. There are many varieties of health apps available for purchase from app stores. Some are designed to help consumers make healthier choices in their everyday life by offering advice about fitness or nutrition. Others help doctors and patients communicate from afar, like apps for diabetics that automatically sent glucose readings to their primary care physicians. Some apps are aimed at physicians themselves—many apps combine mHealth with electronic medical records (EMR), allowing doctors to keep accurate records that are easily accessible.
