Features & Capabilities

A simple, reliable roller derby game control app with local mode, CRG Scoreboard compatibility, and built-in vibration alerts for key timing moments.

JamReady is a roller derby game control app for running jams, lineups, periods, and timeouts.

It is designed to keep core bout operations clear and quick, whether you are using it in local mode or connecting to the community-standard CRG Scoreboard.

A key feature of JamReady is vibration alerts, both for on-device games & when connected to a remote scoreboard. Instead of relying only on visual cues, the app provides haptic feedback at important timing thresholds (including end-of-clock situations), helping operators stay aware while multitasking during live gameplay.

Features:

  • Controls for start jam, stop jam, timeout, and undo
  • Clock displays for lineup, jam, period, and intermission
  • Built-in vibration alerts for critical timing transitions
  • Local/offline mode
  • Remote mode compatible with CRG Scoreboard
  • Team panels with timeout and official review tracking
  • QR code support for remote setup

JamReady was developed with support from the 501(c)(3) organizations Seattle Derby Brats and Rainier Roller Riot. Special thanks to both organizations for testing.

Disclaimer: JamReady is an independent app and is not officially affiliated with the CRG Scoreboard project.
