All participants in this single-arm pilot study will receive access to Plan to Thrive. This mobile care management program is comprised of modules including educational interventions, health behavior trackers containing built-in reminders, symptom monitoring, and navigator services (see attached content). Access to intervention modules and individualized navigator services according to patients' needs as captured by 1) their patient-reported outcome (PRO) assessments via Plan to Thrive's symptom monitoring feature, and 2) patient requests. Following the baseline assessment, participants will engage with the Plan to Thrive app for a 90-day period.

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).

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).

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).

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 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 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.
