  • No Slideover or Split-Screen = Terrible

    By NotReallyMe
    Digitizing 30 year-old algos scores 3 stars because a middle-schooler could have done that; unless you innovate from there 3 is the best this thing should get. From there I give harsh deductions for lack of slide-over and split-screen capabilities that would allow some actual work with it. Swipe-left backspace like Apple native calculator? Nope. Same middle-schooler could’ve done all these things.
  • Does not work with iPad and newer IOS.

  • Screen doesn’t line up

    By nyc-fin1
    The screen is out of alignment
  • Glitchy

    By Jake908
    App no longer works. Please fix. The calculator doesn’t rotate to the full view and stays in just the basic calculator mode.
  • Rotate screen doesn’t work

    By ca90py
    Although they say they fixed this two years ago. I still can’t rotate the screen so half the functionality is useless. I reinstalled the app but still didn’t work. On top of that, good luck trying to reach the developers to report.
  • Disappearing App

    By Louise soderbergh
    I purchased it, used it once, and now it won’t open on my phone. This is unacceptable HP!

  • HP 12C The Best!

    By Haystack1
    Superb software reproduction by HP of its original outstanding HP 12C pocket calculator! Works well on iPhone XS Max and iPad Pro 11” with iOS 12. Thanks HP, well done! The latest update displays numbers outside the display window. Please fix.
