LOK-Registrering is an Android app developed by Riksidrottsförbundet IdrottOnline. It falls under the Lifestyle category and is a useful tool for sports leaders who organize activities for children and youth in their sports clubs. The app allows leaders to quickly and easily register attendance for their activities and ensures that all participants are included in their club's LOK application.

LOK is an economic support system for sports clubs that organize sports activities for children and youth. The more people who participate in the club's activities, the greater the support. The app is free to use and has a demo mode that anyone can use to test its functionality. However, to log in to the app, you must be registered with the authority to register attendance for LOK activities in IdrottOnline. If you need help, contact the administrator of your club.
