Comments on RpnCalc Financial Calculator for Android

★★★★★ Eliel Cooney · Dec 26, 2022
I still have and still use the original Hewlett Packard HP12C. Mr Falk's app has been on all my Android phones. He perfectly replicates the original hardware, which remains to this day, 41 years after its introduction, the gold standard for financial calculators. This app is highly recommended.
★★★★★ Riaan Jordaan · Mar 6, 2018
I have been RPN-ing since 1976 (yuk)! Been on an actual HP12C since they were launched... And then Ed Falk launched this - as the description says "The best financial calculator on the market." Period....
★★☆☆☆ DCB DCB · Jan 10, 2023
Amortization schedule does not show up in window. Looks like black type on black background. So it is unreadable. Sent a few emails to developer for help or refund but no response. Financial RpnCalc installed on a Google Pixel 6. Otherwise, this is a fantastic HP 12c alternative.
★☆☆☆☆ Kenneth Li · Apr 30, 2024
The publisher of this App does not appear to support the product which doesn't appear to be working any longer. The app keeps switching to the publisher's scientific RPN calculator without prompting, and I have to reinstall it many times to the point that I'm now really fed up.
★☆☆☆☆ Jim Gluckin · Jan 25, 2023
Program no longer allows loading and saving of program files. The calculator program immediately quits if you attempt to load or save a program file. Granting access permission to both media and files does not help. Vital function for extended usage. Have sent several feedback explanations but nothing heard yet.
★★☆☆☆ Budana Prijadi · Jul 2, 2018
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?
