The goal of this clinical trial is to learn if a mobile app program for people with a history of cancer can help treat distress. The main questions it aims to answer is:
Do participants use the Tools for Coping with Cancer Calm Health mobile app and do they find it helpful?
Does the Tools for Coping with Cancer Calm Health mobile app improve mood, quality of life, and help with coping?
Participants will be asked to use a 13-session self-management program (Tools for Coping with Cancer) housed within the Calm Health app. Participants will use this app on their own device, in their own home. Participants will have access to the program for 8 weeks and will be asked to work their way through the program at their own pace. Participants will be asked to complete questionnaires about their mood, quality of life, coping, and experience with the app three times: at the start of the study, after 8 weeks using the app, and then 3-months after using the app.
