Mobile health gives patients access to healthcare professionals outside a clinical setting. Mobile health techniques can also provide medical care to those who do not have easy access to a healthcare professional due to travel expenses, time, or other barriers. Additionally, mobile health units can reduce wait times, allowing patients to be seen more quickly than if they were to go to a hospital or clinic.

Mobile health is a beneficial approach to healthcare for many, as it can reach people who live in remote locations or who are experiencing homelessness, and it can help prevent unnecessary trips to the emergency room or the local urgent care clinic. Mobile health techniques include applications for mobile devices such as cell phones, tablets, and more.

Since the beginning of the COVID-19 pandemic, there has been an uptick in mobile health use globally. Specifically, mobile COVID-19 testing and immunization applications have helped people get tested and vaccinated quickly and close to home. They can reach a large population as mHealth applications are accessible through not only personal devices, but also often through libraries and shelters.

Mobile health also enhances immunization convenience, which is crucial to many. Several apps have been launched in various countries with features that make it easier to book an appointment to receive the COVID-19 vaccine. The most common feature of these apps is that patients can enter their location and the app then finds the nearest immunization clinic and available time slots. Additionally, mobile health benefits healthcare workers through apps that allow them to track immunization rates in real time. These apps can help healthcare workers see who is vaccinated, as well as the number of doses that have been received, missed appointments, and more.

Mobile health apps have been beneficial through the COVID-19 pandemic by increasing immunization opportunities for the public and providing insights for healthcare workers. Mobile health apps are a good way for patients to maintain their health in areas beyond the pandemic as well.
