## What is Ampelino?

Too loud in class or at daycare? Ampelino makes noise visible – as a traffic light everyone can see.

Ampelino is the noise traffic light for teachers and early-years educators. The light shows at once how loud it is: green, yellow or red. That way everyone learns to judge their own volume. Measuring uses A-weighting and a moving average, so the light doesn't jump at every scraped chair.

FREE

### 5/5 — Praxistauglich

*2026-05-03*

Eine Lärmampel, die nicht nach Kindergarten aussieht. Nutze sie in meiner 8. Klasse über AirPlay am Whiteboard, funktioniert super und die Anzeige flackert nicht bei jedem kleinen Huster direkt auf Rot. Praktisch in der SEK I. Klare Empfehlung!

### 5/5 — Genau wonach ich gesucht habe.

*2026-04-19*

War schon länger auf der Suche nach einem simplen einstellbaren System, welches sich gut in das Unterrichtsgeschehen integrieren lässt.
Funktioniert auf jeden Fall bedeutend unkomplizierterer und besser als eine physische Ampel.

### 5/5 — Moderne App

*2026-04-17*

Ich nutze die App regelmäßig in meinen Klassen. Die Übertragung auf das Smartboard klappt zuverlässig, was die Visualisierung für die Schüler deutlich einfacher macht. Funktioniert an das SmartBoard angeworfen auch mit gesperrtem Bildschirm. Insgesamt eine solide Unterstützung für den Unterricht. Designtechnisch ein deutlicher Schritt nach vorne von SchoolTool.
