Despite the advancements in medical technologies, healthcare continues to pose all levels of challenges of complexity, affordability, and accessibility worldwide. In contrast to healthcare access, mobile access is becoming almost omnipresent across the whole world. This provides a strong foundation for mHealth — the use of mobile communication for health services or achieving health outcomes.

Mobile technology has expanded dramatically around the world. Now, mHealth—the provision of health services enabled by mobile communications—is poised to revolutionise the way healthcare is delivered. The features of smartphones like sensors, location detectors, wireless connectivity, and cameras, etc., make it ideal to use for health applications. Mobile devices allow you to contact medical experts easily.
