Table 4 A detailed description of the main features of the application

Personal account

• There are 4 different spaces in the app: (a) Public space: it contains general information about the application and PA benefits in cancer care pathway; (b) Beneficiary account: it allows access to the content of AP advice and PEP, with statistics and self-monitoring; (c) HCP account: it allows the creation of beneficiaries accounts, the consultation of the data filled in by the same beneficiaries only and the communication with them; (d) Administrator account: it allows the consultation of all the beneficiaries and HCP data.

• Opening the HCP account requires authorization following an interview with the HCP.

• Opening the beneficiary account is a simple feature, which only requires the first name and the telephone number. The account allows the user to store data already recorded by the user and to monitor the various recommendations of the application. the account can be opened on different devices: laptop, phone, or tablet.

Form filling (In put)

• The form can be completed by the HCP or the beneficiary himself. it contains information such as age, sex, weight, height, stage of the cancer care pathway, therapies, risks related to PA, and current functional capacities. to inform some items, beneficiaries are asked to contact their physicians.

• The beneficiary can optionally in personal space complete the international physical activity questionnaire (IPAQ) and the quality of life questionnaire (SF12).

PA advice (Output)

• The content of the PA advice is composed of three parts: (a) general advice: the beneficiary is asked to be more active and less sedentary; (b) specific advice: advice adapted according to the clinical situation of the beneficiary, such as anemia, dyspnea, the stages of pre-treatment during treatment or in palliative care, etc.; (c) some practical tips for becoming more physically active.

PEP (Output)

• The content is composed of several parts: (a) general presentation: information filled in the form, program components, duration, and frequency per week; (b) aerobic exercise training; (c) muscle strengthening; (d) pelvic floor exercises, (e) balance exercises; (f) stretching exercises; (g) self-assessment sheet.

• In the document on the application, we have video links, which explain the exercises and how to follow the program.

• The exercises are chosen to require the minimum physical capacities, to adapt to the maximum of people.

Social connectivity and virtual coach

• A chat space exists between the beneficiary on the one hand, the virtual coach, and/or the PS on the other hand. the beneficiary can ask questions if necessary.

• A forum that brings users together is available allowing the exchange of the experience of using the application and its content;

Self-monitoring

and self-evaluation

• The self-monitoring is daily, which consists in giving feedback to the beneficiary according to the objectives of the day. An agenda is systematically programmed from the date of registration for this reason. the agenda can be modified, if the beneficiary has missed his training, he can therefore postpone the session.

• In the personal space there is the calendar/plan of activities which contains the programs and/or the day's advice.

• Self-monitoring and self-assessment are carried out daily and at the end of the program. The information is entered every day for AP and every training session for PEP.

• Self-monitoring is facilitated by the graphs and curves visible in the personal space and which reflect the data provided daily by the beneficiary: rate of compliance with AP advice and PEPs, performance over time in several exercises, etc.

• some videos explain the methods of self-monitoring and self-assessment.
