Frequently Asked Questions
Does the classroom countdown play music?
No. MerryMeter never starts audio automatically, so it is safe to open during lessons.
Will it fit an interactive whiteboard?
Yes. Fullscreen mode scales to landscape displays and keeps the main number readable from the back of the room.
Can I reduce the animation?
Yes. The fullscreen controls include a reduce-motion option, and the site also respects your device’s reduced-motion preference.
