Participants are seen in the survivorship clinic and receive education about potential late effects and the survivorship application on study. Participants enrolled in this study will be asked to complete two self-administered questionnaires at 4 time points. Questionnaires will be designed and made available electronically, to be completed on the participant's personal mobile device (e.g., mobile phone).

The knowledge of the participant will be measured using a 12-item questionnaire that assesses the awareness of their treatment and health issues in four categories: (1) diagnosis, (2) treatment, (3) risks, and (4) recommended follow-up. A scoring system has been devised which will give a score to each questionnaire out of 100 possible points. The change in participants knowledge scores >=20 points from baseline will be reported.

System Usability Scale (SUS) consists of a 10-item survey with five response options from Strongly agree to Strongly disagree. The scoring of positive questions is done as follows: The user's score is reduced by one point. For example, if the user's score is 4 for question 5, then the outcome score will be 3. The scoring of negative questions is done as follows: The user's score is subtracted from 5. For example, if the user's score is 3 for question 4, then the new score will be 2. After all the scores are determined, the sum of the scores is multiplied by 2.5 to make the range between 0 and 100. Scores above 68 are considered above average. The proportion of participants with an acceptable usability score > 68 will be reported.
