  • Expensive app and values don’t show in window

    I just bought this expensive app as I love the HP 12C. Shocked to see the numeric values aren’t even in the proper window in landscape mode. Wow.

    Landscape does not lock on since IOS 11.0.2 released
  • No updates for IOS

  • Need Updates!!!

    I use this financial calculator in my business. I was a mortgage loan officer for 14 years & I've been a Realtor for the last 7 years. This calculator came in handy when my clients wanted an idea of what their house payment would be. I started getting pop up notices with IOS 10 & now it won’t even open with IOS 11. I’m disappointed with HP that they would charge a high price for this app & then forget about it by not developing updates. There was one update a week ago for 64 Bit Version, otherwise, the last update before that was 5 YEARS ago!!! I still have my original HP 12C, but it’s not convenient to carry with all the time. Come On HP, Get With The Program!!!
  • Please update!

    I purchased my beloved HP-12C in 1983 and it still works like a charm. Love the iPhone app and thanks so much for the 64-bit update!

    It is ridiculous that you have to rebuy this insanely expensive app if you previously owned the 32 bit version when you upgrade from iOS 10 to iOS 11. Really sad.
  • Great app

    HP calculator user since 1980 (34C), great to have the iPhone version. Happy that HP updated it to 64 bit finally! :-)
  • Doesn’t work on iOS11

    Should issue a refund if the product will not be supported.

    Superb software reproduction by HP of its original outstanding HP 12C pocket calculator! Works well on iPhone 7+ and iPad Pro 10.5” with iOS 11. Thanks HP, well done!
  • Settle down it's been upgraded.
