How do I use Q Clock for my classroom?

Select an exam or activity preset, click Play, then click Fullscreen to display the timer on a projector. Send live messages like '5 minutes remaining' to the display.

What is the Rundown mode?

Rundown mode lets you create a sequenced list of timed segments (like a TV show rundown or church service order). Segments auto-advance or wait for manual cue, with over/under tracking per segment and total show elapsed time.

Can I control the timer from a separate device?

Yes! Click 'Create Remote Display Link' to get a shareable URL. Open that link on any device (tablet, TV, phone) and it shows your timer in real-time. Control everything from your phone while the display shows on a projector or TV.

Is this really free? What's the catch?

Yes — 100% free. No signup, no watermarks, no limits. Q Clock is part of Jolly Grid's free tools suite.
