Daher kann ich nicht beurteilen, ob die App „nur“ ein Wrapper um die Engine ist, oder diese funktionell erweitert. Was ich sagen kann, ist das sie auf meinem M1 iPad Pro sehr performant läuft und einen guten Eindruck macht. Wenn die App kostenlos bleibt gibt es keinen Grund sie nicht auszuprobieren. Ich würde auch einen Kaffee sponsoren, wenn es mal eine „Buy Me A Coffee“-Option geben sollte. Vielen Dank an den oder die Entwickler! **Developer response:** Vielen Dank für Ihre ausführliche Bewertung! Es freut uns sehr, dass die App auf Ihrem M1 iPad Pro so performant läuft. Zu Ihrer Frage: Excalidraw bildet die Grundlage, wir haben das Erlebnis aber um einige Funktionen erweitert - unter anderem um eine große Auswahl an Schriftarten und anpassbare Hintergründe. Der aktuelle Funktionsumfang bleibt kostenlos. Über das Angebot mit dem Kaffee haben wir uns wirklich gefreut. Eine solche Option gibt es momentan nicht, aber wir behalten die Idee im Hinterkopf. Wer uns in der Zwischenzeit unterstützen möchte, kann gerne einen Blick auf unsere anderen Apps wren - Bewertungen wie Ihre helfen uns aber ohnehin am meisten. Vielen Dank, dass Sie die App nutzen! ## Frequently asked questions about CanvasPrism ### What is CanvasPrism? CanvasPrism is a private, offline whiteboard application for iPhone and iPad.
