  • Better than the Real HP12C!

    By Pappysnap
    Trust me. This app is spectacular! I've used Hewlett Packard calculations since my early years in real estate in late 1970's. I didn't think it could be improved but I was wrong as this emulates all the good features of the physical HP12C and then adds benefits. It is so great to be able to look at the financial registers and see what values are in N, I, PV, PMT, and FV. One of my favorite features is using Clx to eliminate the last number in the X register. The physical HP12C eliminates the whole number so you have to start over. Being able to look at the tape is HUGE if you're wanting to see or verify that you have included all the variables in a long calculation. My fellow REALTORS® don't buy the Hewlett Packard iOS version. I used to train agents at board offices in Tennessee and Alabama on the use of the HP12-C and I've written articles for our nation trade publication, Real Estate Today. I've used the iOS version From Hewlett Packard and this version from Mr. Brock. This version wins HANDS DOWN. I would pay twice or even three times the asking price on 12/8/18. It's unfortunate that Ernest Brock has to battle against Apple's tweaks to it's operating systems which in turn causes tweaks in the App. This is THE go to app for financial calculations in the residential and commercial fields in real estate. To Mr. Brock: I am saving this review so that I can repost it due to an Apple reset.
  • Worth every penny and every dollar

    This calculator is the best thing since tax laws and depreciation for calculating IRR and mortgage amounts on real estate transactions. You really need this if you ever bother to get in the CRE world.
  • Best Financial Calc - Period

    It's fabulous...I have it on my iPhone and iPad and no longer need to use the separate 12C
  • Tape

    I like it that the calculator has a tape function
  • Great HP-12C replacement

    By JMS-3.14159
    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.
  • Love my HP12C!

    By Northeast NY Mom
    I’ve been using an HP12C calculator for 25 years. I was thrilled to discover this app which allows me to carry my favorite calculator with me on my phone. Superb app! Beautifully and accurately designed and executed.
  • Fully Functional

    By DW Reader
    Im a die hard handheld 12c'er. In fact, my vintage one dates to 1987. The functionality of the app matches the original in all material ways. Well done.
  • Improved on original

    By Capthorne
    I learned to calculate on a HP12C & this app had the same feel-only better. Truly useful for those of us who still favor Reverse Polish Notation calculators.
