Une réplique merveilleuse de la HP41CV
Perfeita
Perfeita, dunciona exatamente como minha antiga HP41C!
Simply the best HP41 emmulator
I've been using my original HP41CV since ~ 1980, and just love RPN and the functionality and the history of this groundbreaking calculator. I use an emmulator on my PC, but was challenged finding a good emmulator while on other mobile platforms. This is the first app I purchased once moving to IPhone in 2017 and I it's the only calculator I use. Works just like the original and always brings me great memories, making me smile every time I use it.

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.
Genial. Igual que la auténtica.
Para cualquiera que la tenga o la añore. Como llevarla encima.
Extraordinario. Viaje a 1986. Saludos.
Me gusta mucho.
Peggiorato
Prima dell’aggiornamento era super
Adesso non si riesce a togliere il fastidiosissimo “ritorno” dei valori di input sul display . Roba da epilessia !!!!!
Applicazione cancellata, con rammarico

Fantastica!
La migliore calcolatrice programmabile di sempre che gira a meraviglia sul vostro iPhone!
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.

Outstanding Calculator
I had the “real” HP41C when I was at Uni 40 years ago. Still today it is the best, especially with RPN. Having this as such a well developed and supported App is an absolute Godsend ! Very well done.
Poor implementation
Functional, but barely. More about nostalgia.
For example, could not figure out how to switch between the degrees and radians mode and had to look up arcana on the Internet (EXQ ALPHA R A D ALPHA, if you’re interested) when a complete and proper user guide would have been so much useful! Heck with all the screen real-estate to spare, why not go so far as to make it user friendly!
BTW the RND (round) function does not work, while FRC (fraction) does.
Please fix this thing if you’re going to charge money for it!

So good and realistic
It feels so good to be to use my old HP41C again. Had one in Elec Eng university course and have missed it ever since. Well done to the developer and thanks for keeping it maintained.
Latest Update Caused Problems - Now Fixed!
UPDATE - The display issue from v7.6.1 is fixed - via 7.6.2. The calc is now back to the great tool that it has been for quite a while and I look forward to continuing to use it for another few years. Thanks.
PRIOR - The most recent update may have made for compatibility with the latest iOS (I haven't tried it yet on my iPhone and likely won't based on this experience) but it no longer works on my iPad that has an older iOS. The background graphics no longer scale up to the screen size so the touch points for the calc do not agree with the visual indications for the buttons. Avoid this version. Wait until it is fixed if you have an iPad with an older iOS.

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!

Eccellente applicazione! Sembra davvero la calcolatrice! Altamente consigliato!
Mazel Tov!
I wore out my HP-41 calculator but it was the thing that brought me back to programming after a nauseating experience with FORTRAN 77 in 1981. I wrote nearly 200 programs on that calculator. It got me through engineering school, taking the PE, working on the Hubble, B2, and 7x7s. I’m glad to have it back, even just as a calculator. I’m curious: Can I still write a subroutine to cause the calculator to automatically shut down when I turn it on using flag 11?

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 !
Idem
Come altra valutazione con l’unica differenza che invece di averne due, ne ho sempre posseduta una sola messa a riposo da quando ho trovato questa splendida App.
The REAL thing...
Latest speed enhancement is phenomenal! Thank you. Now if we can have it always “ON” when it comes up, then it would be perfect! Is there a setting that would have turn on automatically when it starts?
