Absolutely top

I‘m very happy with your 41CV app. Absolutely close to the original. But i could not find any prefs to change the decimal separator from point to comma and the digit grouping from comma to point. An update therefore would be great.

Perfekt!

Eine großartige Umsetzung, so nahe am Original wie möglich. Die ausgezeichnete Ergonomie des HP 41 mit seinem idealen Tastenabstand funktioniert auch mit dem Touchscreen. Ich habe mir die App aus Nostalgie gekauft, verwende sie aber jetzt jeden Tag als meinen Standardrechner.
