Qrenteerings app is developed to use individually (No Server mode), with server-side scripts (Web Server mode) or with QREvents application (QR Event mode), to organize rogaining or score orienteering competitions with QR codes as controls on course. But the app is capable for more. Especially, with use of QREvents application.

Mode "Web Server Event" is for use, when organizers set registration site on web server. Users will get registration codes to enter the event using Qrenteerings app. As an example, users can take a look into app's work, while registering with course code "course01", registration code "pass1" and server URL "". These registration codes may be scanned (see sample). Some sample QR codes for controls are provided. Scan them in event view one by one with some interval and send to server to see app in work. Alternatively, you can type controls code with app's built-in keyboard.

Advanced users with some programming skills can set up their own servers, even on local networks. App use some API calls, which should be implemented in server side software, namely, connecting of user, getting course information, uploading of visits. If you are interested about details - contact me.

Mode "QR Server Event" is for use as client, while app "QREvents" on another device is a server. Enter teams' bib number, which is set by organizer on QREvents. Then scan event's QR code from QREvents (printed or from screen). You are ready to go. When finish control is taken, display teams splits for reading with organizers' QREvents application. That's it!

App is able to scan QR codes in low-light conditions using torch switch provided in scan view.


Users can take advantage to use countdown timer for intervals up to 60 hours. Timer starts, if control title's first letter is "S", and stops, if control title's first letter is "F".

If you like to use automatic timer start, you can set "mass" start time.
