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 lessWhapper Stan
Definitely 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.chopperjon
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.BobinSF94109
Great
Hard to find a decent calculator on iPad, try this one.Yes MLB rocks
Faithful replica of an old favourite
This App faithfully recalls an old favourite rpn calculator and it works very well. It's my favourite calculator on my iPhone.Mindful mapper
No landscape mode...useless!
Why assume that everyone will use this in portrait mode? No way to change it that I can find. Deleted...T. Watson
Simply amazing
I don't normally write reviews but RPN-70 is just too fantastic to not get excited about. Apple should list this app under their Education category in the App Store and make it a must have for every college bound students. It is the best HP emulator in the market. If you are a fan of HP calculators, this is it, and it is free!! Thank you CuVee. Now is it too much if I ask for an iPhone version?Show lessSoggydog

Awesome Calculator !
This is a really cool Financial calculator. Just like using the original HP-70. Accurate to the penny.
Hmmm, I wish they'd come out with a version for my i-Phone. Happy to pay for it. Great job!Iowa_Florence
