Classroom Noise Meter – Ruhe

Ruhe turns your iPad or iPhone into a friendly noise light for the classroom. A cheerful mascot shows at a glance how loud the room is – and quiet work gets rewarded instead of noise getting punished.

HOW IT WORKS • Green: the mascot smiles – nice and quiet. • Yellow: it gently says “shh” – a little quieter, please. • Red: it covers its ears – and the flames go out.

COLLECT FLAMES While the class stays quiet, one flame after another lights up around the mascot. Twelve flames complete the ring – time to celebrate! If it gets too loud, all flames go out. Only positive feedback, no scolding.

MADE FOR LESSONS • Timer with ring display and start/stop button • Projector view: show the noise light full screen on a second display while you keep the controls • Adjustable sensitivity, or automatic calibration in 5 seconds • Lock the controls with Face ID so nobody in class changes anything • Light and dark appearance, screen stays on

PRIVATE BY DESIGN Ruhe only measures the volume. Nothing is recorded, stored or sent. No account, no ads, no tracking.
