  • 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!

  • Won’t rotate to landscape on iPhone!

    By Commercial Appraiser
    Purchased this on my employer’s iPhone 6 after using it fine on my iPhone 8 Plus. He paid $14.99 and it won’t rotate to landscape to give him all the financial functionality. We are both long time 12C users. Very disappointed. Is there a solution to this HP? Thanks
  • Love this app, but...

    By kayakkr
    I love this app, because it’s just like my physical calculator, which I use every day. However, I bought this $15 app on iTunes, and now I’ve switched to a Samsung Android phone. Do I get access to my already-paid app from iTunes on Android, or will I have to pay another $15 or so to get this on my new phone? Thanks and happy holidays!
  • Landscape functionality does not work

    By iws11
    I am unable to see all the calculator keys when I turn my phone horizontally (landscape). Bug has not yet been fixed.
  • Doesn’t work with voiceover

    Fine app , but not recommended if you’re blind. Need a refund
  • Unbelievable

    By Gina & John
    Disappointed before the app finished downloading. App Store said $14.99 but HP charged me $42.78. Doesn’t bode well for a financial calculator ...
  • HP 12C

    By Scott - frustrated 2018
    I just downloaded (August 2018) the HP 12C App on my iPhone and I don’t have access to the full screen and functionality. I didn’t realize I had my screen on lock mode. All is good.
  • Excellent Calculator

    By Not dependent
    This makes it easy to have a full HP 12c on my iPhone and iPad. If you want pure HP 12c, it does not get better than this. I would like to see an HP 19BII app for the iPhone and iPad. I prefer the 19BII over the 12c since the 19BII has a back button, solver mode, better placement of the enter key and a multi-line stack display as part of numerous improvements over the 12c. For the physical calculators, my 30 year old 12c is still in use. My 28 year old 19BII has a cracked battery cover and the display is questionable. It would be great to have the 19BII re-incarnated as an iOS app. Until that day, get this 12c app.
  • Screen rotation

    By angieg629
    Worked great at first but now the screen won’t rotate to be able to do financial calculations which is the whole point of buying this app. Very unhappy. Uninstalled and reinstalled the app many times no luck.
