    Love the two rotating display versions. Used HP 15C for years--and now always with me again!
  • It simply needs an update.

    I would give this app 5 stars if the folks at HP would simply UPDATE it! Seriously it can’t be that much work to fix the problems that keep creeping in with each new update of ios. Come on HP - take some pride in your work please and get on the ball here!
  • To use on iOS 12, delete & Reinstall

    Updated to iOS 12 and it stopped working. I deleted it and powered down iPhone. Restarted and re-installed and it works again.
  • Not as good as Android version

    I had this on my Android phone and loved it. But on the iPhone 7 Plus the graphics are not sharp. For the price paid, it should be perfect. Really the only reason to get this, instead of other RPN calculators for iPhone, is the look and layout are exactly like classic from the the 80’s. In short, at least half the price is for the looks. I knew that up front and I’m ok with that. And for Android they absolutely nailed it. But for iPhone 7 Plus, it needs work...

    This is a superb emulation of the original Hewlett-Packard HP 15C calculator. I should know. I had an HP 15C when it was new. It took me through physics and calculus in college and the start of my engineering career. Regretfully a trip though the washer and dryer in the pocket of a jacket killed that calculator. I have bought and used other calculators but the 15C has always remained my favorite. When I saw this app, and it was made by Hewlett-Packard, I did not hesitate to purchase it. Reports the the app does not work with the latest iOS are out of date. Hewlett-Packard updated the app and it works flawlessly. As of this review I am using iOS 12.1.4.
  • Fix this please

    This is a horrible mess. I am stunned that HP, a company long known for quality hardware, would let this appear on the App Store. When subroutines finish executing the contents of the x register flash endlessly on the display. The only way to make it stop is to press some key which of course changes the contents of the x register and pops the stack! For a while, pressing the function key f then prefix would lock up the calculator, displaying the mantissa, instead of timing out after one second and returning to a normal display. Now it’s ok. So that’s going to be an intermittent bug. But come on, people. Just fix the flashing subroutine result problem. Where do I go to get my $15 back?. Retro 15C works just fine and it’s free.
  • Display flashes?

    Write a simple program. Run it. Display flashes. 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.
  • Quality app - great graphics

    I found this app to be wonderful. At first I was frustrated with it as it would not switch to landscape mode which is were most of the functions become available. Found I had to switch off rotation lock to get the app to work in landscape mode! Love the look of this app, great quality graphics! And I love RPN calculators. Expensive app, but then all HP products are expensive.
