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. ## Frequently asked questions about Ampelino ### What is Ampelino's core function?
