Description

Jamzo is an app created for roller derby non-skating officials (NSOs) to simplify the management of the 30-second penalty box timer.

Three timer modes
• Blocker Timer: track 30-second penalties for blockers.
• Jammer Timer: manage jammer penalties with ease.
• Dual Timer: combine both roles in one convenient screen.

Specifically built for the penalty box
• Timers that are easy to start and follow.
• A clear, glanceable interface.
• Reduces stress during games and scrimmages.

Jamzo helps make penalty box management simple, reliable, and rule-compliant, so you can focus on what matters most: keeping the penalty box running smoothly without confusion.
