HEALTH APPS DON'T SAVE PEOPLE PEOPLE DO

摘要

Silicon valley thinks it has found a way to ad- dress lifestyle diseases (hypertension, Type 2 diabetes, and the like) that are increasingly straining global health care systems: smartphone apps. This year venture funds have poured about $150 million into companies whose mobile software programs track and analyze exercise, diet, sleep, and other factors that contribute to good health. Much of the software tries to motivate people by turning healthy living into a game or contest, pitting users against their co-workers and friends, or doling out virtual rewards for staying virtuous.
