Request Kalender blendet deine privaten Termine direkt in den Dienstplan deines Crew-Tools ein – als farbige Punkte über der Tagesleiste. So siehst du auf einen Blick, wann dein Fitnesskurs, Zahnarzttermin oder ein Geburtstag mit deinen Diensten zusammenfällt, ohne zwischen zwei Apps zu wechseln. So funktioniert's Du hinterlegst die Abo-Adresse (ICS-Link) deines bestehenden Kalenders – etwa iCloud oder Google. Die Erweiterung lädt die Termine direkt auf dein Gerät und zeigt sie im Dienstplan an. Zusätzlich lassen sich Feiertage und Schulferien deines Bundeslandes einblenden. Deine Daten bleiben bei dir Es gibt keine Server des Entwicklers. Alle Termine und Einstellungen werden ausschließlich lokal auf deinem Gerät gespeichert und niemals an Dritte übertragen. Kein Tracking, keine Werbung, keine Konten. Kostenlos Request Kalender ist kostenlos und bleibt es. Hinweis: Request Kalender ist ein unabhängiges Projekt und steht in keiner Verbindung zu einer Fluggesellschaft.

Verdict
The clearest difference is price: Request Kalender at Free against iConvert's $2.99. Request Kalender also leads on ads (none vs shown) and update cadence (every 3 days vs every 3 months). iConvert's advantage is iOS requirement (12.0 vs 15.0). On in-app purchases and device support there is nothing between them.
