Enhancing Cancer Care: RestoreMe App for Personalized Nutrition and Activity in Cancer Patients

This is a single institution feasibility study of the updated RestoreMe app. The investigators plan to recruit 150 participants to this study with participants being recruited either prior to the initiation of their curative treatment or during and after completion of their cancer therapy. This design will allow the investigators to assess the feasibility of using the RestoreMe app in both the active treatment setting and follow up/survivorship setting. Information gathered from this feasibility study will inform future trial design for prospective intervention using the RestoreMe app.
