Health app users beware: Column
USA Today

Patients in my clinic increasingly use health apps on their mobile devices. Many of these apps track health metrics, such as weight or calories eaten, while others go a step further and help patients make sense of their symptoms or suggest diagnoses.

By 2015, an estimated 500 million people worldwide will use a health app, turning the industry into a $26 billion business by 2017. Despite the promise of these apps, I’m not ready to recommend them to my patients. The sheer number of health apps is staggering, with more than 40,000 apps categorized as “health and fitness” or “medical” in Apple’s app store alone.
