Got questions? We have answers!

Can't find what you're looking for? We're here to help.

How does the timer work?

It is a countdown timer. Tap the +/- buttons to set minutes and seconds, then start. You can pause, resume, and adjust time mid-run. For count-up, the Stopwatch widget is a separate tool on the whiteboard.

How do I set the duration?

Tap the +/- buttons to add or subtract minutes (1-minute steps) and seconds (10-second steps). You can adjust anytime, even while the countdown is running.

Will it work on a projector?

Absolutely. Fullscreen mode is designed for classroom projectors. The large, clear display is visible from the back of a classroom.

Can I pause and resume the timer?

Yes. Pause at any time if you need to address the class, then resume where you left off. You can also reset to start fresh.

Is there an alarm when time is up?

Yes. You can enable audio alerts that play when the countdown reaches zero. The sound can be turned on or off depending on your classroom needs.

Can I use the timer with other tools?

Yes. Drop the timer onto your whiteboard alongside any other widgets you need: group generator, seating chart, scoreboard, picker, lesson plan, or anything else. Every tool composes on the same canvas.

Does the timer work offline?

Once the page is loaded, the timer works completely offline. No internet connection is needed during use.

Is the timer good for students with special needs?

Yes. Visual timers are often helpful for students with ADHD, autism, and other learning differences because the display makes time awareness clearer.

Why should I upgrade to Pro?

Pro unlocks unlimited cloud-saved whiteboards with every tool embedded as a widget, multi-device sync across school computer, laptop, and tablet, priority support, and 30 monthly AI credits that work across the lesson planner, rubric generator, quiz generator, and worksheet generator. You can also request new tools and we ship them within 7 days.
