HP 15C Calculator

Has worked great through numerous versions of iOS now 15.1. Would love an upgrade to enable cutting and pasting for entering and saving numbers. Still have my old HP, used it with a pencil and paper. Now it would be better to cut and paste numbers to and from other programs. It’s a great calculator, could be better.

Have used 15C on iPhone 10 for over 2 Yrs, with no issues. Upgraded to 11pro with 14.3, so far no problems👍

The digit are not in they’re place on the screen of the iPhone X plus

Ive been using the 15C since the early ‘80’s. This app has been a welcomed addition. RPN is a habit and once mastered, you can’t use a normal calculator. Thanks for this app. Been using it for years now

Great calculator direct from HP, all the same algorithms as the original and it includes the manual. The portrait version, which is a nice touch to include, could be a lot better though. On the iPhone XR the digits aren't in the display area at all.

Love this app. Used a 15-C getting 2 engineering degrees in my distant past. In addition to the display misalignments reported reported on the iPhone 11 by other users, with this latest update, the “flip” function no longer works when trying to return to landscape mode after pressing the “15-C” logo at top left.

The latest upgrade broke it, on my iPhone 11. The numbers are now out of place in both orientations. Please fix...!

Please update for iOS 11!!! I paid for this expecting it to be well supported. It works on my old 5C which is now, apparently, my calculator.

I’ve been using HP scientific calculators for forty years. The only HP15 I trust is the version offered by HP, but they haven’t updated it for IOS11. When will loyal HP customers’ needs be addressed?

Why after updating did you get rid of the original key sound? If I wanted an iPhone tap sound I would download any calculator app for free! Please bring back the kchunk sound effect! Please!
