  • The Best Financial Tool Ever Created

    By MirabalC
    It simply makes the original HP12c look like a toy. If you open the hood by touching the HP12c icon a new world of options appear. Charts, Graphs, printing tapes, Manuals. I have no idea as to why Apple nor Mr. Ernie Brock the creator of such amazing tool do not make people aware. I have never met Mr. Brock other than the personal respond he provides to my queries. Is so powerful and easy to use that makes me look like a genius in front of my clients. I cannot look at any other cellular brand because I cannot have this App.Period!! Thank you, Mr. Brock.

  • Great Financial Calculator

    By mauifelix
    Mimics HP-12. This the best calculator for the IPhones of you are used to an HP-12. All functions and more. Tape feature is super useful. That alone worth the price. Works great on both IPhones and IPad.
  • Love this app

  • Great HP-12C replacement

    I’ve used this app ever since Brock wrote the program for my Palm Pilot last century. I’ve used it ever since. Everyone in financial services should have this app on their smart phone and iPad. It's better than an HP-12C, more functions, audit tape, currency conversions updated daily.
  • Favorite Calc app

    Renews my fondness for RPN
  • One great financial calculator

    By Bluenose Biker
    All the features of my standalone HP 12-C and more. All at a price less than the cost replacement batteries for HP 12-C. I work in real estate and love the conversion feature, particularly currency conversions that utilizes current rate data.
  • Better than my 12C!

    By Papa G48
    I have used a 12C for over 30 years. In fact, I still have my original HP12C but don’t even take it out of the desk drawer now that I have Ernie’s version. It’s like a 12C on steroids! AWESOME!
  • Nearly Perfect

    By uhgolfguy1
    It’s better than the real 12C. The only note is that the stock ratio lookup doesn’t work,but that’s seriously nitpicking.
