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.

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!

The calculator stopped displaying in landscape mode. Does anyone know how to fix this?

Superb software reproduction of the original, outstanding HP 12C pocket calculator! Works well on iPhone 15 Pro Max and iPad Pro 11” with iOS 17.

Love having the app since the real 12c can stay in office. Really surprised that still after 4 years the blue functions on the right hand column is absent!
