Die offizielle RabenApp von Klett für die Grundschule, passend zu Nussknacker (Ausgabe ab 2021) und Rechenrabe (Ausgabe ab 2022). Mit der RabenApp können die Lerninhalte des Mathematik-Unterrichts von Klasse 1 bis 4 selbstständig zu Hause oder im Klassenraum geübt werden. Dabei können die Inhalte jedes Schuljahres einzeln hinzugefügt werden, so dass die App auf den individuellen Kenntnisstand der Kinder in jeder Klassenstufe der Grundschule zugeschnitten werden kann. Das kann die RabenApp: • Für jedes Schuljahr werden jeweils die 4-6 zentralen Themen intensiv interaktiv geübt und gefestigt. • Die Kinder erhalten während des Übens ein direktes Feedback zu ihren Lösungen. • Der übersichtliche Auswertungsbereich hilft Ihnen bei der Einschätzung des Lernstandes des Kindes. • Die Aufgabentypen sind den Kindern bereits aus Nussknacker und Rechenrabe bekannt und passen so als interaktive Ergänzung genau zu den in der Schule verwendeten Materialien. Klasse 1: • Zahlen bis 10 • Rechnen bis 10 • Zahlen und Rechnen bis 20 • Rechnen über die 10 Klasse 2: • Zahlen bis 100 • Plusaufgaben bis 100 • Minusaufgaben bis 100 • Malaufgaben bis 100 • Geteiltaufgaben bis 100 Klasse 3: • Zahlen bis 1000 • Addition bis 1000 • Subtraktion bis 1000 • Multiplikation bis 1000 • Division bis 1000 Klasse 4: • Zahlen bis 1 000 000 • Addition bis 1 000 000 • Subtraktion bis 1 000 000 • Multiplikation bis 1 000 000 • Division bis 1 000 000 Wir freuen uns sehr über Feedback.

Verdict
The clearest difference is review sentiment: SchoolRoom at 81% against RabenApp (2021)'s 40%. SchoolRoom also leads on update cadence (every 2 months vs every 6 months). RabenApp (2021)'s advantage is monetization model (free vs free with in-app purchases) and iOS requirement (13.0 vs 17.5). On price, ads, in-app purchases and device support there is nothing between them.
