The application is intended for participants of the Cyklotrek event. It allows groups to complete the race by scanning QR codes at the start, stations and at the finish. For the main settings of the application, it is necessary to download the (large) configuration QR code, which is sent to each group a few days before the event. After the end of the Cyklotrek (by scanning the QR code at the destination or the time expires), the data on the visited sites are sent for evaluation.
