Excellent emulation
The pro version is just great - has a lot of extra cards with an extensive manual on each card’s functions, i.e. TVM calculation card etc. There are a lot of customisations available to the core HP 67 calculator. Thanks for the hard work of putting this all together, this seems like the only calculator [emulation] one would ever need. The calculator skin is also great, and the red display makes it authentic. Looking forward for future versions.

Back to 5 stars
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.

Response from developer
One star because of a single feature you're missing?? Blocking portrait mode was not an arbitrary decision. It was forced by a number of graphical issues showing up when running in iOS 13. In order to release an update supporting Dark Mode and the new file sharing features in time, portrait mode was disabled. Meanwhile, it has been fully restored, working better than ever. And to answer your question: I'm not on drugs and never will be.
Love It
I used the HP67 at college back in the 70s, this emulator is just like the real thing. Well done.
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.
Undecided
I tied to write a review and gave the app 3 stars, but it wouldn't let me post it. Therefore I have downgraded my review to one star. The app is okay for the small price, but there are many program cards on the developer website which you should be able to import directly from the app, rather than having to connect to a computer and fiddle around.

Like Owning a New HP-67
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.

Superb emulator of Hp-67!
I own an HP-67 calculator and have used it a great deal over the last few decades. This app does a wonderful job of emulating the HP-67 functions, and having programming support is such a great feature. In many ways, the app is even better than the original - much faster, better and easier programming, and not having to pay for all those pre-programmed function cards. Such a deal!

a labor of love
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 emulator. Great customer service. Questions were answered immediately!
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.

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 ?

Very cool astronomy computational feature added!
The SOLAR function that the developer added (replacing the BOND function) is not the same as the programs in the Avigation Pac (AV11, AV12). Rather, these are high-powered algorithms with multiple terms to give highly accurate results, including calculating the sun's declination, right ascension, and equation of time. It is an extremely cool add-on feature. Plus, version 2 greatly expanded the "built-in" function set. All together, this is one incredible hot-rod of a 67!

RPN-67 Pro
Anyone who is a long term HP-67/97 card programmable scientific calculator user, like me, would be absolutely delighted with this APP for the iPad. The author of this APP has implemented an exact simulation of the HP-67 hardware and has also provided optional enhancements, with additional maximum programming steps, faster execution speeds and enhanced output display options. This APP would be a great backup for any HP-67/97 owners/users as these are no longer supported, but they may have existing useful card programs they could easily run on the APP. All of the original HP Application Pacs library program listings and vendor support are available on the website. The latest version of the APP has a large number of convenient scientific constants built-in. jjb-oz

Brilliant
I used my HP67 extensively during my working years and recently had it rebuilt (new card reader wheel). I was almost incredulous to find this App for my new iPad Mini. It is amazing. It does everything the real calculator does and does it better. It looks and functions beautifully. I've downloaded my favorite programs and they are instantly available. All owners and users of classic HP calculators should be aware of the author's astonishingly fine work. He's a genius and was very accessible to help with an issue resulting in my misunderstanding. Thank you Willy Kunz.

I am a collector of HP emulators on my iPad. The HP-67 is beyond spectacular! The magnetic card animation is worderful. The wealh of programs from the different downloadable application pacs and users soltuion make this emulator a real gem! I must say that the programmer behind this emulator is an ace programmer. This comes from teh author of 70 programming books!! Buying the Pro version is money well spent!

Great!!
I have the 45 and the 70 apps. They are fantastic!
The 67 app is also wonderful :)
Please Willy, can we have the 35??
Everyone who likes HP classic RPN calculators should buy these apps.
