As can be analyzed, mHealth apps are used among millions of people across the world in order to monitor their health and are also used by healthcare providers to connect with their patients and access medical records. With the fact that people can access mHealth apps through the touch of a finger, this also means that security needs to be much tighter because sensitive data cannot afford to be leaked to hackers. Furthermore, these mobile health apps face ethical and legal challenges because again, this private information does get shared with unauthorized 3rd parties but are challenging to fight against because there is no law that specifically governs healthcare apps. With the security, ethical, and legal concerns, there does come a bright side that society is coming together to improve their health altogether and be active in maintaining physical and mental well-being. Overall, mHealth will be staying with us in the long term, which is why we need to find the most optimal way to utilize these apps while securely taking care of sensitive information.
