Participation in this study starts with setting up a study specific profile on the app and entering information including email address, age, ethnicity/race, cancer diagnosis, as well as other optional information for the profile (example health goals or current health conditions). Participants will then be prompted by the app to complete three questionnaires about their ability to self-manage their survivorship-related needs, their perception of their survivorship-related illness symptoms and perceived health related quality of life. They will be prompted on the app to complete these questionnaires again at the 3, 6 and 9 month intervals of using the app. It will take about 20 minutes to complete the questionnaires at each measurement time. The only additional information that will be reported from the app for the study is the amount of time and features of programs accessed during the study period.
