Before long, your doctor may be telling you to download two apps and call her in the morning.

Smartphone apps already fill the roles of television remotes, bike speedometers and flashlights. Soon they may also act as medical devices, helping patients monitor their heart rate or manage their diabetes, and be paid for by insurance.

The idea of medically prescribed apps excites some people in the health care industry, who see them as a starting point for even more sophisticated applications that might otherwise never be built. But first, a range of issues — around vetting, paying for and monitoring the proper use of such apps — needs to be worked out.

“It is intuitive to people, the idea of a prescription,” said Lee H. Perlman, managing director of Happtique, a subsidiary of the business arm of the Greater New York Hospital Association. Happtique is creating a system to allow doctors to prescribe apps, and Mr. Perlman suggested that a change in the way people think about medicine might be required: “We’re basically saying that pills can also be information, that pills can also be connectivity.”

Simple apps that track users’ personal fitness goals have already gained wide traction. Now medical professionals and entrepreneurs want to use similar approaches to dealing with chronic ailments like diabetes or heart disease.
