HP 12c Financial Calculator

I have used HP Calculators since 1973-4 initially HP97 I think. Having it available on the iPhone and iPad is sensational. However my new iPad Pro will not open. The app motive is on the desk top but when actioned it turns screen to portrait shows black screen with HP logo and then returns to the desktop. Also in transferring to ne iPad Pro I have lost the anniversary model. 😩

This is the best 12C app out there as you would expect, however it needs updating to support iPhone 5, 5s, 6 and 6 plus screens. It really looks poor on my 6...

A very good calculator spoiled only by not having Bluetooth keyboard support.

A true application of the original handheld, except for the sound. Not having the option to switch keystroke sound off is annoying and disappointing.

Broke out my old HP12C to work out a ‘change date’ problem. It churned but gave me the answer I needed. Out of curiosity, bought the HP12C app then ran the same problem on my iPhone 15. The answer appeared instantaneously. Missing are the calculation steps’ crib notes on the back of the original.

This app works great on larger iPads. But on my mini, the numerals aren't within the result window in portrait mode.

Not good at all, better save your money, and after years of using the original version, they don’t even provide a manual to figure out this piece of junk, ripp off

This calculator always worked perfectly, but recently, it lost the ability to flip into landscape that showed the financial functions.

Can’t use the full functions of the calculator

It is a great and old school HP12C. But it needs a software update to look better! Please HP keep track on it!
