RPN-70 HD is a complete, photo-realistic simulation of the financial hand-held calculator HP-70 from 1974. It handles loan amortization, saving plans, depreciation, and much more with ease. What users said: "Hard to find a decent calculator on iPad, try this one." "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 student. It is the best HP emulator in the market." "An incredibly well-engineered calculator app, and free, to boot!" "This is a really cool Financial calculator. Just like using the original HP-70. Accurate to the penny." Features: • Photo-realistic look based on an existing device • "Live" register view in landscape mode • Animated keys with click sound (adjustable volume) • All functions and operations of the HP-70 fully implemented • Simulation of the HP-70's computation time (optional) • Correct wrong number entries by swiping left across the display • Cut/copy/paste of display value • Visual indicators keep track of stored input parameters (optional) • Stack shown right below display (optional) • 10 non-volatile memory registers (optional) • Built-in short manual with many examples The HP-70 was discontinued after just one year. It is one of the rarest calculators, hard to find in any condition. NOTE: RPN-70 HD is a faithful simulation of a vintage HP-70 calculator, as has been verified against a real device using the examples in the Applications Cookbook section of the HP-70 manual. In certain cases, what may appear like a bug of the app is actually an idiosyncrasy of the HP-70. IMPORTANT: The HP-70 requires exactly three input parameters from the top-row keys, at least one of them being either "n" or "i". In other words, you can't use PMT, PV, and FV as input parameters simultaneously. A version for the iPhone named "RPN-70 SD" is also available. Visit the website: www.cuveesoft.ch
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.
Great
Hard to find a decent calculator on iPad, try this one.
No landscape mode...useless!
Why assume that everyone will use this in portrait mode? No way to change it that I can find. Deleted...
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?
Perfect
Exactly what I was looking for. A real HP RPN machine.
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!
Excellent
Mr Kunz is a master designer. I just got his HP 45 emulator which too is fabulous. Very thoughtfully designed, complete with crisp instructions, useful settings. It's a joy. I never had an HP 70 but looks like a simple, elegant product. Thanks!
