• Rate of enrollment [ Time Frame: 4 months (baseline to follow-up) ]
  The investigators will explore the feasibility of the study procedures by examining rates of enrollment (defined as the percent of eligible individuals who consent to participate).
• Rate of retention [ Time Frame: 4 months (baseline to follow-up). ]
  The investigators will explore the feasibility of the study procedures by examining rates of retention (defined as percent of consented participants who complete follow-up measures).
• Rate of app usage [ Time Frame: 4 months (baseline to follow-up). ]
  The investigators will explore the feasibility of the study procedures by examining rates of usage (e.g., number of days participants access Plan to Thrive, percentage of prompts read).
• Patient knowledge and adherence to follow-up care recommendations and health behaviors [ Time Frame: 4 months (baseline to follow-up). ]
  This outcome will be assessed through a Health Behaviors Measure designed by Dr. Garcia for use in survivorship care planning (SCP) studies. This 14-item measure uses a 5-point Likert response scale. The content corresponds to SCP, NCCN and ACS recommendations for cancer survivorship. The investigators have slightly modified and shortened that measure for the present study to ensure it covers all the survivorship concerns addressed by Plan to Thrive. All patients will complete this measure at T1 and T2, and as part of the Survivor Symptom Update in Plan to Thrive.
• Patient activation [ Time Frame: 4 months (baseline to follow-up). ]
  Patient activation will be assessed using the "Patient Activation Measure" short form. The 13-item short form of the Patient Activation Measure is a reliable, validated (0-100 point) scale that assesses patient knowledge, skill and confidence for self-management. This will be administered at baseline (T1) and follow-up (T2).

• Symptom burden [ Time Frame: 4 months (baseline to follow-up). ]
  Symptom burden will be assessed with computer adaptive tests (CATs) from the PROMIS measurement system. PROMIS is an NIH-sponsored system for measuring patient-reported health status, including physical, mental, and social well-being. Participants will complete the PROMIS Anxiety, Depression, Fatigue, and Pain Interference computer adaptive tests (CATs), which administer the minimum number of items necessary to accurately measure patient-reported outcomes while minimizing participant burden. These measures have all demonstrated reliability, precision, and construct validity based on their correlation with legacy instruments. All participants will complete these measures at T1 and T2. In addition, short forms of these PROMIS measures will be used, along with select items (physical activity, nutrition, alcohol use) as part of the Survivor Symptom Update in Plan to Thrive.
• Health-related quality of life (HRQoL) [ Time Frame: 4 months (baseline to follow-up). ]
  HRQoL will be measured with the FACT-G7, administered at baseline (T1) and follow-up (T2). The four-item needs assessment measure was used in prior studies and is based on questions used in a clinical initiative at the RHLCCC, which assess participants' supportive care needs. Items assess in what areas participants need support and service (e.g., coping, managing stress).
• Patient satisfaction [ Time Frame: 4 months (baseline to follow-up). ]
  Patient satisfaction will be assessed using the System Usability Scale (SUS), adminstered at follow-up (T2) only. The System Usability Scale (SUS) is a simple, ten-item scale giving a global view of subjective assessments of usability. This ten-item scale has selected statements that cover a variety of aspects of system usability, such as the need for support, training, and complexity, and thus have a high level of face validity for measuring usability of a system. SUS is a Likert scale, which is based on forced choice questions, where a statement is made and the respondent then indicates the degree of agreement or disagreement with the statement on a 5 point scale. SUS yields a single number representing a composite measure of the overall usability of the system being studied. SUS scores have a range of 0 to 100.
