Excellent app

I have used this during many years as my old 32S started to fail in the buttons. This is almost as good as an original HP calculator. I recently found how to fix the 32S on YouTube so I will have a go on that as it is nice to have proper clicking buttons.

Great App

This app works well and is one of the best RPN apps I have used!

Fast, superb!

I love this app. I wish there was an HP48 app with this quality.

Lik originalet

Hade denna för många år sedan. Fortfarande grym. Mycket bra app som simulerar originalet mycket bra.

Awesome HP42 emulator

However, it would be really nice if the app could be updated to take advantage of the bigger screens on newer iPhone models. I keep using it, but it’s the only app I have that does not fill the iPhoneX screen! A missed opportunity.

Äntligen

Brukar aldrig skriva en recension på appar, men idag när jag hittade denna känns livet lite lättare. Har saknat en RPN-räknare i mobilen som fungerar.

Rounds everything to the nearest whole number

Useless, as everything is rounded to whole numbers, with 0s in the decimal positions

Best calculator around.

I have always used hp RPN calculators in real life and this is my favourite app, on iPhone and Mac, emulating one. The developer pays a lot of attention to details and regularily improves the app. Visit his homepage and see other variants as well as good documentation. If you agree with the above, make a donation to keep him going. Björn Henning

Nice feeling

I loved my HP-42. Today my old calculator doesn’t work any more. So it’s wonderful to have the opportunity to experience old days feeling of using it. Thank you, mr Okken, and a great projekt!
