MOBILE APPS DEFINED
Mobile apps are programs or tools used with hand-held information and communication technology (ICT) devices, such as smartphones or tablet computers, to perform specific functions. Due to their mobile nature, these apps can be used anywhere the owner is located; however, usage is limited by Internet accessibility. Apps can be used for a variety of purposes. As a focus of the current article, mobile health and medical apps are designed to help people track and document contributors to their health (e.g, sleep, diet, exercise) or to track and document measures associated with a medical condition(e.g, hypertension or depression).
