  Ryan Goering: This is a good reliable apk! The developer also provides perfect customer help based on latest experience. I really have fun having the HP Business calculator interface on my phone. It's truly the best of both worlds on a single device.

  aaron bradford: Dear Mr Falk, Thank you for your assist in recovering the RpnCalc Financial apk that I had previously purchased. It's a tremendous apk and better than the HP12C calculator itself! May you have continued success in the work you are doing. And once more, thank you your help. If I should give more than 5 stars I would! Have a blessed day! Sincerely, Aaron Bradford

  Jay BeEn: I have been using this Apk for over a decade and have been using the HP-12C at my desk since that calculator first came out over 30 years ago. I no longer have to worry about leaving the physical HP-12C behind when I leave my office because the Falk RpnCalc Financial Calculator works just as well and takes no more room than my cell smartphone which I am carrying anyway. Thanks for making a good Apk and for supporting it through the years.

  Stephen Rybacki: This is an perfect application, and the help is unbelievable! As a bit of a calculator junkie (I even have one the the original Casio graphing calculator from the 80s), I have an affinity for them for whatever reason and this one is top notch. Plus, the developer helped me receive through some problems with the Google Play Shop and I am a very satisfied camper!

  David Rubenstein: Best financial calculator on the shop I've been using this application for a lot of years, probably since first became accessible, 8, 9, 10 years maybe. I've consistently found this to be the best financial reverse polish notation calculator on the shop, this contains the HP12C; and suggest it highly, five stars, and would give six if I should :)

  Howard Pattis: I found this apk a lot of years ago and it has accompanied each fresh cell smartphone purchase I have created. It's emulation of an HP 12C has created it indispensable in my line of work as I no longer need to carry a separate financial calculator with me. Add to that tremendous help from the developer!

  Alejandro Ochoa: I have been using this apk for years. As a Financial Advisor, I use it for on-the-fly calculations in client appointments all the time. In college I used an HP12-C and since then this has been my replacement. A must have for any financial professional.

  B. Sanders: Used the HP-12c through college and in finance since then and love it. Now I can leave the 12c at home and still have the features on my smartphone. Well done, Ed and thank you.

  Richard Dreskin: Unreserved appreciation and praise. The only negative review is someone who cannot create his smartphone work. I own and have used a HP-12C since 1976. I wonder what should be on HP's mind that they don't wish to allow Falk call this an HP-12C emulator -- It is an improved and modern 12C. Its existence and widespread use can only add to the considerable stature of the original.

  DK Sakota: Love this Apk. To me, it 100 times better than my old HP 12C. If you own a HP 12C, you owe it to yourself to receive this plus you won't have carry around other little machine. It's "AWESOME" !!! :-)

  Perfect apk - exactly like a HP12C, but faster and without the limitations.

• 

  Steven Koskie: If you need what a 12C does, buy this apk and skip all the gratis ones. Don't over think it or waste your time. Buy the apk and go to work. I've not found anything a "true" 12C will do that it won't.

  Jim Holden: For those of us who know that RPN is the only notation that reflects the method that we humans actually experience mathematical thought, and who remember RPN financial calculators fondly, this particular calculator apk is the *only*. one worth considering.

  Steve Pilgrim: The best financial calculator apk... for preserving the techniques, algorithms & habits you may have formed while using a famous handheld financial calculator. This turns my Pixel XL into that old mate every time I begin the apk.

  Harry Chaffee: I have been using a ver of this apk for years. I love having a full RPN Financial calculator with me all the time. It's even better than my HP 12C because it has a larger stack and it's always visible on the scree. It makes longer calculations so much easier when you can see the stack right there. And the few times that I've required help, the developer has been extremely fast to answer and assist out. I highly suggest this apk.

  Marty Brown: I've been using a financial RPN calculator for about 15 years. They are, to me, so much simpler and logical to operate. This one on the Play Shop is the best one accessible. It is quick, accurate and easily displays in either portrait or landscape mode. It is worth every penny charged. The author is solid and doesn't modernize just for the sake of updating.
