12Calc ROCKS!!

What a fantastic App that helps me continue my 30+year real estate career as I always have using this amazing tool!

This is the gold standard of Financial Calculators.

, Long before the personal computer, iPhones and the internet the HP 12C. calculator provided the answers to my financial calculations. Now my favorite calculator is as close as my phone, it’s always with you. This app has additional features not found on the original HP. The currency converter is very accurate and uses current exchange rates. Best of all, the app cost less than a set of replacement batteries for your legacy HP 12C.

Best…been using since Palm Pilot

This is the best RPN Financial Calculator available. I’ve been using it since it was available on the palm pilot. As a licensed CFP, a financial service professional, this app on my phone was critical to my success.

A perfect 12C Emulator

This has been my go to 12C since I got my iPhone 6s (now on my iPhone 12). I use it daily. My real 12C has been collecting dust since (but I’ll never discard my decades old pal). This is THE BEST 12C app for iOS; very reasonably priced plus bonus functionality and great in-app help. Thank-you to the developer.

Best 12c calc

Tried many financial calc. This is simply the best.

Excellent!

This is my most favorite app on my iPad.

Fantastic calculator, problematic update

First of all, nothing beats 12Calc. There is no substitute unless you are using a real 12C, but then 12Calc has all the speed of your iPhone. The latest version, however, is problematic as the font is now white instead of black. Depending on your situation it can be very hard to see. I wish I did not upgrade so I could have kept the previous color scheme of black numbers on a lighter background. Update: Years later this app has been maintained and still works wonderfully. Thank you!

Greatest Calculator

Ernest Brock has done a phenomenal job with this App. I first downloaded a version of this years ago when it was offered free for a short time. Then (I believe) HP asked Ernie to make some changes. I was extremely worried when I updated my first iPhone, because I thought I would lose this App. But it kept on working. Finally with my iPhone 7, I finally broke down to repurchase the newer (and improved) version. If you are a fan of HP-12C calculator, then you will likely find this App very intuitive, and I won’t go into describing all the ways it can be used. But some of the novel features include: * Currency converter, and current currency values can be updated whenever you want. *. A “tape” feature, so that you can see what an adding machine tape would show if it were part of the HP-12C calculator. And although I don’t use it for much more than a basic calculator with financial and real estate (loan, mortgage, PV, etc) calculations as I did for years with my regular HP-12C, I can honestly say that I use this App ALL THE TIME, especially during tax season! Finally, over the years I have had 2-3 emails with Mr Brock, who has always been prompt, honest, and provided me with valuable tips and help. Just what you want with a developer. So, stop reading, and go buy the App! You will find it very worthwhile1 2020 is here and my earlier review still stands. Great App. Great support. Go get it!

Awesome!

If you are a fan of the old HP12 with RPN this is well worth the purchase. I use it on my iPhone and iPad and often comes in handy. . . Usually when I least expect it! Thanks

Love having 12 c on my iPhone

Works well
