Update 7.6.2
Auf iPad nach dem Update wilde Zuordnung der Tasten. Keine gezielte Eingabe mehr möglich. Nichts geht mehr! Schade!! Ergänzung: Nach dem Löschen der App und einer Installation der Version 7.6.2 funktioniert alles wieder wie gewohnt!

Dieser Taschenrechner ist ein Muß für jeden UPN Fan
Sehr gute Simulation des von mir heiß geliebten hp41 plus CAS - was kann man mehr wollen? Ich danke dem Entwickler dafür !
Prima Idee, good idea
Good idea to "rebuild" this very use- and helpful pocket calculator for an iOS device. Really sad, my hp41 is now gone(black LCD display) but this piece of software can hopefully be the substituion...👍. Thanks a lot for programming!
Fast so gut wie das Original
Super umgesetzte Lösung! Arbeite seit knapp 40 Jahren damit und jetzt habe ich den Taschenrechner auf dem Smartphone immer dabei! Klick fast wie auf dem Original!
Funktionsunfähig seit dem Update vom 01.11.2014
Leider ist die Funktionalität nach dem Update. vom 01.11.2014 nicht mehr gegeben! Die vorherigen Versionen liefen tadellos und das App wurde von mir sehr oft benutzt. Betriebssystem : IOS 5.1.1 Hardware : IPad 1
Super Idee...
...den "alten" HP41 als Zombie wiederzubeleben. Nachdem es schwierig wird, den alten Akkupack meines original HP41 immer wieder mit neuen NiCd zu bestücken, kommt mir das iPhone gerade recht. Die RPD (UPN) Emulation war mit ein Grund für dieses iPhone... Funktion = wie damals... Ein erstes Programm hat gefunzt, wenn ich auch wtwas aus der Übuzng bin. Eigentlich müsste der auch schneller laufen können als der Taschencomputer, aber möglicherweise, habe ich noch nicht die angeogen Handbremse. gefunden. Aber andererseits weckt es nostalgische Gefühle, die Gans über das Display fliegen zu sehen :-) Bin echt happy :-) P.S. Fehlt nur noch eine Kartenleseremulation....
Absolutes Muss für alle Freunde von UPN und HP-41
Ich benutzte seit 1985 den HP-41CX. Dieses App bringt den besten Taschenrechner aller Zeiten aufs iPod touch. Alleine schon dieses App würde den Kauf eines iPod touch rechtfertigen. Einziger Wermutstropfen gegen über dem Original ist die Tastatur. Denn die Tasten des Originals sind unübertroffen. Somit entgeht einem auf dem iPod touch das tolle Tastengefühl. Dieses App ist ein absolutes Muss für alle Freunde von UPN.
So good I retired my HP-41CV!
This is a great program! The interface is so well designed and uses all of the available screen space so that the numbers are readable for this old timer. In the HP tradition, this app exceeds expectations in both quality and performance.
Masterful reincarnation of the original !
Well done! $/feature/functionality it’s like buying a hand held super computer. Holy cow! Not to mention throw-back value for boomer generation :)
This is a great app!
I have been using HP calculators since I bought a HP45 in about 1973 With HP mostly out of the Scientific RPN calculator area this app fills the need! Makes me miss my HP41CV I had (that died after many years of heavy use). Super customer service as well.
