  • Screen rotation still a problem!

    By MRSrun
    Rotation to financial calculator in landscape mode works on iPad, previously worked on iPhone, but no longer does. Version history states this was fixed, but I can attest it is not working on my iPhone X. Please address this issue. Once this is corrected I will upgrade my review. Thx!
  • If it doesn’t rotate to landscape mode

    By Chicofuji
    Check to see if you phone screen is in locked rotation. Mine was. App works perfectly if you unlock rotation in the control panel.

  • Size adjustments for iPad

    Would be nice to have the full-size 12C when used on an iPad in portrait mode.
  • HP 12C app

    By arizona1001
    I have on my I phone but it will not go to financial view when I rotate my phone.. I just purchased again for my wife’s phone got it downloaded and I still have the same problem. You said you had fixed this app a year ago but apparently not.. I have now paid for two applications that do not work... Not very good advertising!!!!

    The calculator I got is not the one advertised. How do I get my money back?
  • Hp 12C still not functioning on iPhone X

    By dfgfgv
    Hp 12C is still not functional on iPhone X other than as a four function simple calculator. Rotation for the financial functions. The developer is very remiss in not providing proper updates. I’m now carrying my original 12c device the avoidance of which was the reason I purchased the app in the first place. Apple should take all HP calculator products out of the store until these issues are fixed for those of us who have already paid for a non-functioning calculator app.
  • Outdated and no updates

    By CatholicGuitar
    If you are using a reasonably modern iPhone, which has no “home” button anymore, then the only way to switch apps is to power down your iPhone. It insists on going into full screen mode and never relinquishes the screen. Outdated, outdated, outdated. This is an orphaned app.
  • HP 12C Good but not supported

    Good app. Looks and works like the actual HP 12C. Does not display full screen on iPhone 6, and most likely newer iPhones. This should be a simple update considering the price, but has not been updated in a year. Would also be nice to display full features in portrait mode. There are less expensive and free competing apps available with these features. I wanted to support HP. Too bad customer experience is not a priority.
  • 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!
