The app is designed to convey safe and reliable information about sports clubs to parents who have already been introduced to the Sgrum service.

The app's main functions include delivery of content, event calendar, sharing groups, emergency communication and safety, rest contact, attendance confirmation, and questionnaire. Parents can receive various messages and photo files from sports club lessons and get real-time information about their children's attendance and group activities.

Additionally, parents can answer questionnaires from sports clubs and lessons in the app, making it easier to deliver the results to sports clubs.
