HP 12c Financial Calculator

Love the 12c and RPN entry. This display is only showing the right side of the calculator. That side you get works great. You don’t get the left side keys which do so much like NPV, IRR, exponents, percentage change, or even changing the number of decimals displayed (it is stuck at 2 decimal places. Until this is fixed and you get both sides, I don't recommend anyone buy it.

Display is not aligned after the upgrade. Please fix!

Big fan of HP 12 C but the display on iPhone X is poor. It does not adjust to the screen on landscape well. It feels artificial. I am sure HP could do much much better... pity as it feels very expensive and is hardly better than copy cat free versions.

True to the original physical HP 12c. There are other RPN calculators for the iPhone, but I want my app to work just like my physical calculator. This does it. Love that I always have my 12c with me. If you don't know what RPN is, you probably won't like this. When I got my first HP calculator in 1976, it took 2 days to get used to the process. But I've never looked back. Much easier way to perform calculations than the standard calculator.

I don't think this APP will run on iOS11. Added Nice to see the App updated for iOS11. Awesome calculator. I have the original HP12C in the office and the HP15C Limited at home.

Finally updated with 64-bit support the day after iOS 11 came out! Thank you.

Thanks for 64 bit

This surely is the definitive iOS implementation of the HP12, but it needs an update or it will not work under iOS 11. For those planning to run iOS 11, do keep this in mind.

Wonderful App - the real thing, other than HP's old tactile feedback! Please update to conform with upcoming IOS.

Shame! You destroy a brand by slacking off on updates. My phone is unstable because of this outdated app but I rely on the 12C daily. Update it or pull it, just don't further frustrate those who have been HP fans for years.
