Description

A dream calculator of the 70's, priced at $1,900 in today's dollars, now on your iPad!
RPN-67 Pro is the first complete simulation of Hewlett-Packard's legendary HP-67 programmable calculator for iOS. Produced from 1976 to 1982, the HP-67's features coupled with its capability to store programs on magnetic cards made it a huge success among scientists, engineers and other professionals. Thousands of programs were written for it. Now you can run them right on your iPad, with more ease and faster than ever before. To get you started quickly, download hundreds of program cards from our website for free.
What users said:
"I am a collector of HP emulators on my iPad. The HP-67 is beyond spectacular!"
"What an application! Perfect visual experience, perfect emulation, even the clicks are pleasant."
"In many ways, the app is even better than the original - much faster, better and easier programming".
RPN-67 Pro is fully compatible with RPN-97 Pro, its companion simulator of the HP-97 calculator.
Features:
• Virtual program and data cards
• Virtual paper tape printer supports all HP-97 printer modes
• Powerful database-driven card manager

Yay, well done. Portrait mode is back. It seems to me that if you had to drop a mode, for the 67 it would have made more sense to drop landscape mode. Anyhow, thanks so much for restoring it.

Best iPad Calculator

This developer is terrific. His apps are really great. The HP-67 is a good calulator made great by the extras added by this developer. The calendar functions are amazing and make it very much like the HP41 or 42s. The integrated share functions make it very easy to send a listing or a copy of the "card" created or a listing. The developer's efforts are truly a labor of love! There is a version of this app for the iPhone and the share feature makes it easy to copy a program developed on one device to the other device or to a Mac for backup...

No longer works

This worked beautifully until the iOS 8.4 update. Now the program closes as soon as you open it. The funny thing is, the free version still works perfectly! So until this is fixed, get the free one instead.

This is by far the best emulation of the classic HP-67 scientific calculator that I have found. When you consider the reliability, speed, and capacity advantages of using the included virtual magnetic card reader/writer (and virtual thermal printer), versus the physical original, it is clear that this app provides exceptional value. That conclusion is only further reinforced when one considers the many performance upgrades, the ready access to the HP applications library, and the built-in program reference guidance provided. A math-oriented young person contemplating a technical career could find their areas of greatest interest by familiarizing themselves with the contents of the classic application pacs.

I love this app as it fabulously recreates one of the most amazing programmable calculators that ever was. Some of us grew on programmable calculators and the HP67 was the king. The app also includes many of the original libraries of magnetic cards. Thank you for creating this!

Outstanding

Every update adds something useful. Design, vision, execution all outstanding. How come the earlier reviews disappear? The most recent update makes an excellent product even better. Breakpoints with a count is very relevant. Not just the core product but every enhancement is well thought out and well executed. I wish there was detailed help attached to the app. Would make it more convenient than having to go to an external site.

Excellent

Best RPN calculator anywhere!!

I purchased the RPN-67 Pro about one year ago when I purchased my new iPad. I have always used a scientific calculator with RPN since college years but didn't want to carry around two devices (iPad and calculator). I hate to admit that I'm old enough to have wanted an HP-67 when they were available but just couldn't afford one. This app is reasonably priced and works even better than the original. Sometimes you see an app that never gets upgraded. The developers of the RPN-67 Pro are in a constant state of improvement. After one year they have added so many new features that it's almost hard to keep up. Just look at their revision history. Everything works great - just like you would expect for a first rate RPN calculator. I definitely recommend the RPN-67 Pro. It's worth every penny, and if I had to guess it will only continue to get better. Tom

Amazing!

This is beautiful! I still have my HP-67 and this is a wonderful copy! It seems to work perfectly.

Full "retro" feeling achieved!

Thanks for writing this app. I recently bought 'the real thing' recently, but now I'm happy to have it embedded in the iPad. Excellently HP-67 look & feel achieved with all features. The handling of magnetic cards - this was a revolutionary feature back then- is brilliantly achieved. I believe that the price of one of those in the '70s was more expensive than a 32Gb iPad today ?
