How RoomTone differs from other classroom noise monitors.

Teachers searching for a free classroom noise monitor usually find a hardware traffic light, a bouncing website, or an installable app. This set of pages explains those categories without fake rankings or paid placement.

RoomTone is a free website: one open-ended Live Reaction, three Goal Challenges, activity presets, no student accounts, and no audio recording. Sleepy Cat reacts and recovers. Loudness pauses goal progress in the other worlds instead of making the animation more chaotic. That is the main product difference, and it is also why some rooms should still use a different tool.

What we compare on purpose

Price and login. What the display does when the room is loud. Whether there is a noise history or alarm counter. Whether the microphone path records. Whether the number on screen is a relative level or a claimed calibrated decibel. We do not invent laboratory scores or user-star ratings.

Other products change. Each article tells you to confirm current features on the other site or app listing. These pages exist to help a teacher choose a classroom cue, not to bury a competitor.
