Just like the original
I just started working on an ms finance and bought this app. I also just bought an original hp 12C. This app works great. It's a dedicated financial calculator. If your reading this you probably know that though... Does all the same calcs the same way and also looks great! I highly recommend this app if you are looking for an hp 12C calculator!!! If you are just looking for a "plain Jane" calculator this is NOT for you!
Now does not open in ios26.3

Bom mas falta suporte ao MAC
No MacOS a aplicação não fica do tamanho correto, gerando um espaço em branco ao lado

App muito bom
No support
App hasn’t been updated in 4+ years. Stored registers will 0 out for no reason whatsoever. Stored number in register will be exponentially higher when you recall it, again, no reason whatsoever. Sent a support ticket in years ago and no answer. Do not waste your money.
Excellent hp emulator
Excellent hp emulator. One suggestion would make it perfect hp emulator: haptic keyboard feedback. Add this and this will be perfect!
Love it
Just bought the App. Really like it!
Thankful it's available
Got my first HP in 1973, an HP35. Yhe Reverse Polish Notation makes everything SO much easier than direct algebraic entry. It is absolutely gabulous to have this app available.
Still faithful after so many years
I’ve been using this app for many years. It is one of my daily go to apps. No exaggeration. I use this every single day. If you’re familiar with the HP-12c, you’ll be completely familiar with this. I’ve never had a problem with it. It just works.
A special shout out to the developer. Years ago, they gave the app a new, sleek, flattened look. I wrote to them about the fact that, due to my vision, I couldn’t see the demarcation of the buttons. The developer restored the original look as an option, which you can find under settings. Thank you for maintaining that.
Some may be put off by the unfamiliar way of doing a simple calculation using what is called RPN notation. In school we learned PEMDAS-based arithmetic notation to enter numbers for calculations. Try spending a little time learning RPN. It helps get rid of parentheses and you control the order of arithmetic operations. It’s better for any multi-step problem other than adding a simple column of numbers.

Won’t work on iPad
Calculator opens at about twice the size of my iPad screen making half the buttons inaccessible. No resize of scroll function available.
Worse, no way to get refund!
Do not purchase for iPad!

Looks good - need haptic feedback
The calculator looks great. You can toggle the sound on and off, however I would really need haptic feedback on the keys to simulate better the experience of the original.
No Split View
I’d give it 5 if it had a Split View on the iPad. Asked but never got a response.
Excelente até o momento
Muito bom até o momento
J’ai retrouvé la HP12C des 80’s !
Quel plaisir de retrouver la HP12C de mes débuts professionnels et sa notation polonaise inversée ! avec les mêmes touches vintage quel plaisir 😊🙏
Wow
Great function and fast, works just like my HP 12c
12c
Being a banker and having app-12c calculator and now this app on my phone has being a great help. There’s one thing I wanted to use this App and that’s on my Mac. I would have to buy the App again for Mac. I think that’s not fair.
funcao data com erro
nao estou conseguindo tambem a funcao data errro8. funcionava normal
Just like the HP12C
Having used 3 different HP12C calculators over 40 years in finance they are like my right hand in familiarity. This app is virtually the same in functionality. The only differences are the tactile feel of the keys and being able to use the ever-rugged HP12C case as a light duty hammer.
Nice
Accurate, has the 12c look option and it’s a great calculator.
Point doesn’t work
This is horrible. Beware. Trying to insert a decimal is nearly impossible because the period won’t register. Shouldn’t have cheaped out because now I have to buy the HP anyway.
Fantastic !!
I use it almost everyday to support my activities of an individual investor.
