HP 15C Calculator

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.

Display digits are grossly misaligned. Quite disappointing for a $15 app. Obviously not tested in portrait mode despite the promise of support in the app store.

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!

The manual pdf button crashes on ios 16

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 the app, but the numbers when using portrait orientation are not aligning with the graphics. Calculator works, but alignment is off.

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.

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!

Shows scientific functions but when purchased, they were not there.

Thank you so much for the latest update. The display is finally back to normal!!!
