The term “mobile health”, known as mHealth, appeared more than a decade ago to describe the application of mobile devices and related technologies in healthcare provision. Prior to mHealth apps busting into the market, there were various types of digital health solutions, but it was not until the launch of Apple App Store in 2008 that the mass market for these apps was totally opened up. Application of mHealth is not restricted to educating users about preventive health care services, but also treatment support, epidemic outbreak tracking, disease surveillance and chronic disease management.
