Leave a Review RPN
Top notch!
This app not only reproduces the HP-70 but improves upon it by adding options for the display and making excellent use of iPad's computing power.
As if that's not enough, it's also an education! – It comes with comprehensive examples which cover every imaginable purpose.
Huge thanks to the developer whose perfectionism is not lost on me.
P.S. One tiny improvement (for me) would be an option to choose a plain background.Show lessDefinitely a five star APP
I just love RPN and have used it with my original HP12C which still works. This APP clones the HP exactly and I highly recommend this calculator.Beautiful Emulation !
Beautiful Emulation of a classic. I love this app and it’s iPhone companion as well. Wonderfully designed and true to the original.
