13 Positive User Reviews for HP 15C Calculator
Update needed
Trying to use my purchased calculator and it will not work with the IOS. Needs to be updated..
Orientation Issue
The vertical orientation places the digits below the display. The horizontal position is fine. All else seems ok.
love the app, but…
upgraded on 5/5/21. the portrait (basic calc mode) on my 2020 iPad Air still has the numbers shifted up out of the display window. Looks good on my mini and iphone.
Thanks for fixing display issues.
The best calculator for my use. Love RPN.
Portrait mode display issue.
The portrait mode has a bug… the display is shifted so that numbers are shifted to the right it’s no aligned with the display window.
Back to five stars!
Thank you so much for the latest update. The display is finally back to normal!!!
Need a 16C Version
I still use my 16C Programmer calculator. I'd really like to see a good version as an app. (One non-HP app is out there but not as high quality.)
Give me access to your code and I'd write for free!
Display flashes?
Now that the calculator division is under “new management”, could we please get an update to stop the display flashing? Write a simple program. Run it. Display flashes. Even just pressing R/S.
This is not how a real HP 15C works. 15C is still an amazing calculator, just wish implementation on iOS was done a little better, a little more care taken, especially by the company that designed and produced it.
Portrait orientation not aligning properly on iPad Pro 11”
Love the app, but the numbers when using portrait orientation are not aligning with the graphics. Calculator works, but alignment is off.
The Original Engineering Calculator
HP created an actual emulator of the ROM of the original HP-15C. Therefore, guaranteed to be faithful emulation of the original! As is the case with the other HP Voyager series calculators. Excellent! My only wish is that HP would release the HP-16C computer scientist calculator as well so I can complete my collection!
Love this calc!
The manual pdf button crashes on ios 16
HP 15C
Superb software reproduction of the original, outstanding HP 15C pocket calculator! Works well on iPhone 15 Pro Max and iPad Pro 11” with iOS 17.

Fails to copy and paste
Those absolutely isolated the HP calculators from everything. Why can’t we copy and paste to and from their digital calculators? Maybe it can and I am just ignorant as to how? I’m a HO-41c users from forty years ago and it is still my favorite! It is so fast! But try getting the result from the calculator to anything else and you are stuck!
