  • Legacy?

    I have had this app for years, and now it’s finally updated for iOS 11. There is another HP 12C app, also put out by Hewlett-Packard called HP 12C Financial Calculator. What’s the difference between the HP 12C Legacy and the newer one? This one appears to have all the functionality as it had before iOS 11, so I am wondering if there is any reason to get the newer one. HP, you could be a lot more transparent in your description of these apps and the “platinum”version as well.

    Thank you for update. Can you please add keyboard SOUND back!
  • Works like my HP12C

    As a finance MBA my HP 12C was rarely out of my hand. This app is exactly the same!!! Of course, you have to use it in landscape mode to get the full calculator. This is not for the average user. You should already know how to use your HP 12C in order to use this app. The learning curve is not insignificant but many a trader, CPA, financial analyst will find this app to be the real deal.
  • Looks good but hard to use

    Nice graphics but often the numbers don't "work" when pressed so you need to keep hammering away at them which is disturbing.
  • Works like the real thing

    I've been using the 12C for years and this works just like the original. Those who want to use simple calculations, or don't know how the 12C functions, don't buy it. I would have given 5 stars but, I think the graphics could be improved.

    It works fine on my iPhone 4G, with all functions available in landscape mode.
  • Beautifully rendered version of classic HP 12C

    Thank you HP!
  • I want my money back

    Does not work as advertised. No financial functions on the iphone. Only basic calculator. ie right side of calculator only. HP should be ashamed of themselves. I want a refund and I will gladly remove the app.
  • Just like the original HP 12C

    Works just like the original 12U on my iPhone 3G. Vertical position shows only math, horizontal is full 12C functions. Keys are smaller but workable. I probably wouldn't use this if I didn't already know how to use the 12C
  • Not worth the price

    The calculator that comes with your phone is much better
