Der dritte Werbungs-Screenshot erweckt den Eindruck...

... diese App könnte viel mehr.

Habe nur gekauft, weil ich mehr vermutete!
„Reingelegt worden“ - nenne ich sowas!

Response from developer

Hallo! Tut mir leid, dass es ein solches Missverständnis gab. Für einige Nutzer ist das Menü mit den Verlinkungen zu den anderen Mathe-Problemlösern eine komfortable Möglichkeit, zwischen ihnen zu wechseln. Aber Sie haben ja die Möglichkeit, Apps zurück zu geben. https://www.macwelt.de/news/Apps-zurueckgeben-stornieren-8307463.html Es bringt uns als Entwickler nichts, wenn aus einem Missverständnis heraus 1-2€ generiert werden und dem Nutzer die App nichts bringt. Daher machen Sie gern von der Rückgabe Gebrauch. Falls nicht, bedanke ich mich recht herzlich bei Ihnen für Ihre Unterstützung! Um solche Probleme zu vermeiden, bieten wir parallel zu den kostenpflichtigen Versionen noch kostenfreie Versionen zum Testen an. Da können Sie sich bei anderen Apps einen Eindruck verschaffen, ob sie Ihren Anforderungen entspricht. Freundliche Grüße
