Study sites can directly interact with patients, and they will be informed when new information about the trial is available or other tasks are ready to be done by the patient. This gives the patient a good overview along their participation during the study. Relevant study documents are stored in the app so patients can check them whenever they need. With built in eSigning capabilities this app can also be used to give consent electronically by signing consent forms directly in the app.
