Industry projections are that how many people worldwide will use healthcare apps on smartphones?

• A. 1 billion
• B. 100 million
• C. 500 million
• D. 50 million

Answer: (C)

The question tests estimating how widely mobile health tools will be adopted as smartphones become common worldwide. With smartphones in the hands of billions and a growing ecosystem of health apps—ranging from fitness tracking to remote care—it's reasonable to expect a large portion of users to engage with at least one healthcare app. 500 million captures a sizable, plausible share of the global population, reflecting broad adoption without assuming that every smartphone owner uses a health app. The smaller figures would underestimate the reach given current growth in mobile health, while the largest figure would imply near-universal usage, which isn’t realistic given access gaps and varying patterns of use. So the best estimate is about 500 million people worldwide using healthcare apps on smartphones.
