Many health apps are based on flimsy science at best, and they often do not work
Health apps offer diet help, heart tests, relief from pain and other things. But many of them don’t work.
Food and Drug Administration has been mired in a debate over how to oversee these high-tech products, and government officials have not pursued any other app developers for making medically dubious claims. Now, both the iTunes store and the Google Play store are riddled with health apps that experts say do not work and in some cases could even endanger people.
