### 5/5 — Must have!

*2026-01-23*

FrischluftCoach hilft mir jeden Tag, meine Feuchtigkeitswerte im ganzen Haus unter Kontrolle zu bekommen. Die HomeKit Integration funktioniert sehr gut und ist einfach zu verstehen. Wenn ich dem Entwickler einen Bug melde, wird dieser immer zuverlässig behoben.
Ich würde mir noch mehr Erfolge wünschen und bei jedem eine kleine Erklärung, wie man diese erreichen kann. Da es aber nicht zur Kernfunktion der App beiträgt, ist das vermutlich nicht so relevant.
Zum Schluss kann ich sagen, die 8€ lohnen sich auf jeden Fall!

### 5/5 — Super App.

*2025-08-10*

Wirklich eine tolle App. Benutze ich jetzt Zeit ca 2-3 Wochen und ich muss sagen die ist sehr zuverlässig. Ich habe in der App 8 Zimmer + Keller eingetragen. Der einzige Nachteil ist dass ein Zimmer nach dem anderen angezeigt wird zu lüften anstatt gleich die betroffenen Zimmer . Wäre super wäre man es ändern könnte.

**Developer response:** Hey Schuny7,

vielen Dank für deine Bewertung!

Das mit der Anzeige für alle zu lüftenden Räumen wird mit dem nächsten Update kommen. Vielleicht kann man das einfach in den Einstellungen dann festlegen wie man die Anzeige im Dashboard / Notification haben möchte. 

Danke nochmal für dein Feedback :-). Und weiterhin gutes Lüften!
