The CDC developed the CDC app, available for free, with a public health focus - its most recent version updated in September 2012. The CDC app states it provides "public 24/7 access to important and timely health information that people can use to protect their lives and loved ones."
With this in mind, the CDC app focuses on public health information aimed at the general public, rather than medical providers. The app offers a variety of resources on a broad range of health and public health topics, making it suitable for a diverse audience.
