"I have been using this App 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 phone which I am carrying anyway. Thanks for making a great App and for supporting it through the years."

"I have been using this app 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."

"This is a great reliable app! The developer also provides excellent customer support based on recent experience. I really enjoy having the HP Business calculator interface on my smartphone. It`s truly the best of both worlds on a single device."

"Seems to `work` on my Pixel 4 under os10 but the landlords advise it`s out of date and request you hassle the dev about it.?"

"I found this app many years ago and it has accompanied each new cell phone purchase I have made. It`s emulation of an HP 12C has made it indispensable in my line of work as I no longer need to carry a separate financial calculator with me. Add to that tremendous support from the developer!"

"For those of you who`ve always wanted an HP-12C calculator but not wanted to spend $$$, this calculator is for you. Very powerful and easy to use...even includes scientific and regular calculations. Well worth the price."

"Purchased thisbobe becase I use Eds RpnCalc all the time. Works for. a decade using my 41C, so it`s damn good. I won`t use this as much but RPNCalc is free so can`t throw Ed a couple $ there. I still am sure I remember C clearing X register and AC clearing all 4 registers, same as RPN Calc and it catches me out often the C clears all registers but awesome program."

"The best app I`ve ever downloaded from the store. I`ve been a user of the original HP calculator for years. This app simply surpasses it in functionality and speed. Great work, Ed."

"The HP 12c was all you needed for a good estimate of complex financial products. This is even better. And you can amaze your office mates by using reverse Polish notation !"

"TMV calculations are off compared to Excel and HP12C . As an illustration, try it yourself and enter these numbers: $100000 (FV), 9% (i), 5 (n), calculate PV. Off by 6%? Is there a setting to make calculations more precise? Revised review: 15 August 2018. Now the calculation result is the same between HP12C and the android app. Thanks for the corrections. Note March 2023: Unfortunately the powerful/flexible feature of saving and loading of programs are not allowed by the system anymore."
