    By Thenitster
    Are you ever going to update this app?? Apple will no longer support the app if you don't. All of those of us who bought it will be hosed. Please take 1 day of work and update it.
  • Click sound, and soon to be obsolete

    UPDATE: I'm changing my rating to 1 star until HP updates the app to 64-bit architecture. I use this app daily in my financial business (when my hardware 12C isn't handy) and I'm worried about losing access to this (expensive) app when iOS 11 rolls out. It seems that HP charged an arm and a leg for this app, then abandoned it. This app is true to the original EXCEPT for the key click sound! It's loud, slightly delayed from the actual button press, and basically a highly annoying sound. If I silence the phone, there is no feedback to let me know whether it registered a button press, and I'm likely to forget to turn the ringer back on when I'm done. Update this to a simple, unobtrusive click and I'll give it five stars. I still carry my real 12c everywhere. Edit: Just discovered you can turn off the clicks, but that doesn't solve the problem of no feedback, and the key vibrate is too long to be functional.
  • Lousy updates

    By mecarboy
    No upgrade for iOS 10. That is really lame behavior for a company as large as HP. And now with ios11 preparing to launch, HP's negligence will result in this app no longer working.
  • Please Update for New iOS Versions!!

    By michaelsjones
    Come on, HP - it's just one little app update. PLEASE keep this app functional, thanks.
  • Not 64 bit compatible

    By rixtunes
    I felt compelled to replace an old 12C-like app that kept showing a warning message that it is a 32 bit app, etc. Apple is sending out these warnings. I paid 3x more for HP's version only to find I have the same 32 bit issues. How can HP not be updating this app--especially at this price? I would steer clear of this app until resolved.
  • Apparently no support for iOS 11

    By Darnovitz
    Just 32 bit
  • I Love This App - Please Update for 64 Bit!

    By J.O.N.4
    I've been using the 12C since the 1980s - you can still buy them new, which says a lot about the calculator that this app emulates. It's indispensable - PLEASE UPDATE to 64 bit so we can use this when iOS 11 rolls out!
  • App owner needs to comply with update requirements

    By Rodgersplace
    Recently received a notice that my other 12 C app was not compatible and would not be available with future upgrades. Purchased an expensive version reflecting Hp as the owner. Trusted that name. Not a month later I get another not compatible notice for the HP 12 C application supposedly owned by HP. Not sure why we keep getting not able to be used for future upgrades. Why don't they just take them off the offerings. Not pleased.
  • Good app, but is it still supported?

    I like the app, but keep getting warnings from Apple that it needs to be updated and won't be supported by the next IOS update
