Eine sehr gute App, vor allem für Programmierer. Aber, schätze auch Mathematiker haben ihren Gefallen daran. Nur schade das die App keine Universalapp ist. Aber so lange es Apple möglich macht, das iPhone Apps auch auf einem iPad laufen, kein grosses Problem. Danke an den/die Entwickler!

Die App ist schon echt gut. Allerdings würde ich mir eine" logische" Festlegung der Zahlenreihen wünschen. Zusätzlich wäre eine Konvertierung in beide Richtungen wünschenswert.
