In these guidelines, we offer advice to help you find the right application for you. At the end of each section, we have summarized the key facts. This checklist is intended to help you in choosing and using health apps. The idea is not to just tick all or a minimum number of boxes since these guidelines do not provide an evaluation of the medical utility or scientific accuracy of the information or recommendations provided by health apps. Under no circumstances should an app replace personal medical advice because only your doctor or therapist can evaluate which treatment is right for you.
