This application provides an intuitive and easy access to a PRO system for patients with cancer. PROs include, among others, follow-up questionnaires and various symptoms. Through this app patients could also check the history of reported data and send other information of interest to the healthcare professionals.

This application does not allow users to register by themselves. Patients are enrolled in the system by authorized healthcare professionals. Therefore their healthcare facility should be part of the STEP system.

Patients under 18 must not use STEP App even under adult supervision.

Patient reported information can be checked by healthcare professionals, if they have the suitable tools within the STEP system.
