About this app
For Pinewood Derby-style racing, as a companion for GrandPrix Race Manager
Read full description
DerbyMobile is the mobile companion app for GrandPrix Race Manager, the race management software which is used by Cub Scout packs, Awana clubs, other scouting and youth organizations, churches, and clubs to run Pinewood Derby–style races. IMPORTANT: DerbyMobile requires GrandPrix Race Manager to be running on the event's race computer, with mobile access enabled, and a local race Wi-Fi network set up. DerbyMobile does not manage races on its own — think of it as a convenient way for race staff to manage race related data and spectators to view certain race data. Are you a Race Coordinator and don't have GrandPrix Race Manager software yet or a subscription to DerbyMobile? Tap "Try Demo" on the sign-in screen to explore the app with sample race data before you commit.
