failureApp. The application is used to record vehicle faults that the driver notices. Through the form, the driver can provide information about the vehicle number, enter a description of the error, mark the status of the error (depending on the risk that a particular error poses to the journey), mark the corresponding icon and, if necessary, indicate a method for temporary elimination of the problem. The program saves a list of reported errors, which can then be confirmed by subsequent drivers or moved to the archive if the error has already been fixed or no longer occurs.
